The wire loop type was EXACTLY what I needed for Iridium Denso plugs. The coin type was not doing it, and the blade type was hard to press together the blades to get the right depth and insert without fearing I'd damage the small raised bump on the arm above the core. THANKS for this video.
I just use the coin style. It's good enough for copper and platinum plugs. Yes when you have the fine tip of the irdium plug you want to be extra careful. I always use a needle nose pliers so not to touch the electrode. I work outside alot and the feeler gauge tools tends to rust. The coin style though cheap holds up better to moisture. Always check the gap because one plug might fit many engines. More times than not I find a plug gap needs adjusted. Thanks for the video. 👍
coin style gap tools are perfectly fine. just don't use the measurement edge to gap it (as shown incorrectly in the video). Instead use the inner circle to lift from the top without touching the iridium.
+Manasvi Putcha I think you're right about the gapping method (I've always done it how you said), but if you think about the geometry of using an inclined surface to measure gap, it's not as accurate as a wire gauge. I think that's the real discriminator. Wire gauges will measure directly between the spark plug tip and the grounding surface - it's much more accurate with the right wire size.
+stevebean1234 +Manasvi Putcha Thanks for your comments guys. We used a coin style in this video to gap only to illustrate the most common error made when using this tool. This is one of the many reasons we do not recommend the coin style. Steve's point is also correct.
Great video, one thing to note, I found that the $3 wire based tool has an issue, the adjustment part bent before the electrode, nothing a little quenching couldn't fix (even though I still had to hammer it out between plugs).
Plug gap is a specific distance determined by the output voltage of the coil. This is why the vehicle manufacturers specify a gap. You should check and adjust the gap to the manufacturer's specification regardless of spark plug.
Holding the spark plug in your hand, with the ground electrode facing down, tap the ground electrode against a flat surface lightly to close the gap up. Afterwards check your adjustment to ensure that it falls within the recommended gap.
If ratings weren't disabled (WTF?), I'd give this video 5 stars. Great explanation of coin vs. feeler gauges. The HD resolution is also a nice touch since the parts of a spark plug are so small, they'd be hard too see in a lower resolution.
When I try use wire gap to check on 0.44 which is my correct gap to use. But when I bought new ngk spark plugs and checked gap using same wire gap your using. I try check and it easily went in so.does that mean i.have push down more to make sure it don't go through?
Good info, but how are you supposed to maintain a proper, even gap? I still have a set of snap on gapping pliers that allows you to gap the plug and keep the ground electrode parallel to the tip, works very well but cannot be used on precious metal plugs. Just bending the ground strap out will give a poor, uneven gap, the tip of the ground strap will be farther away from the electrode then the body.How can we maintain an even gap??
Hi i am trying to learn on my grandpas lawn mower he gave me to play with. how do i close the gap if too wide? just tap it on a piece of wood or use the tool? thanks sorry if stupid question...
In the military we always installed spark plugs with a smear of COPPER GREASE on the threads, and have been also using this same method on Wheel Nut Threads. Standard practice for of 50 years,
They. Have a special zinc coating now that acts as an anti seize in only the right places. Hence why messy copper slip is no longer needed. Saves over torqued plugs too.
task514 In the video it clearly states that for custom applications, the plug gap may need to be adjusted. If you're buying plugs for a car, and that car is modded, then you might not want to use the gap that the stock engine uses.
Maybe if you just gapped these properly from the factory? Just checked all 16 for my Dodge Hemi. .043 is the standard (92145). They're mostly .032 -.041. Why doesn't NGK pre-gap plugs like everyone else?
Thanks for reaching out. Out of the box, the plug referenced, does come pre-gap @ .043. 92145 LZFR5CI-11. But we do recommend you check before installation.
1:42 you're doing it wrong...see the side of the coin with the hole in it? you place the side electrode in there like a bottle opener and gently pry it up, this way it doesn't touch and potentially damage the center electrode. the only problem with those tools is the reliability might be questionable, but they should be accurate enough get the job done.
Your 100% correct. @ 1:42 were demonstrating a common error or misuse when using this type of tool. Many times a user will slide or even start prying on the wrong part.
Barto Vines you can buy one anywhere. an auto store such as advance auto or autozone, ebay, amazon, anywhere. they're only a couple bucks. i have a lisle coin style gap tool, similar to the one i pointed out in my original comment that was being used incorrectly.
I purchased a se of 4 NGK 97138, it looks like al plugs were pre-calibrated for 0.043 and my Manual calls for a 0.044, should I adjust the gap?, BTW I have a 2010 Civic, Thank You
@dusch888 This backfiring condition could have to do with timing or possibly fueling issues or maintenance issues. Generally backfiring will not have to do much with the plug unless it is gapped incorrectly.
Please explain why the coin style tool is not to be used, besides breaking the tip. I'm only concerned about accuracy since this is only what I have right now. I'm just wanting to know if I should not use it at all. Thanks
@undertake782 Do u mean starting from cold? Some engines have a higher idle when started from cold for the first 1-2 min until the oil pressure is regulated. This is done through a cranking/breather vent that goes into ur intake. After the pressure gets regulated then the engine RPMs go down by about 200-300 dropping under 1000. It is normal. Misfires are not on the other hand
My new set of NGK Iridiums are all preset for about .0425. The spec for my car is 0.043. Maybe my coin is faulty? Do I really need to adjust these gaps for such a small amount? What are the effects of .0425 vs .043? Thanks.
icawn Thanks for your question. With such a small gap size difference there is no need to adjust. However, avoid using a coin style gaping tool with iridium spark plugs. These are known damage fine wire ground electrodes and are not 100% accurate. Outside of that thanks for your support of NGK.
I see that you guys show a NGK spark gap gauge tool that is fold out in this video...but i am unable to find this anywhere for sale. I would like to purchase one like this, can it be purchased?
All of the auto part stores around here don't have the right tool. And they all tell me to do what this video said not to do. Since my Haynes manual agrees with this video I don't want to use the disc to change my gap. My spark plugs' gaps are slightly too small and I have to find a way to safely change the gap without the right tool, do you have any recommendations?
I know that ngk recommends not using Anti-Seize, but my service manual from Honda says to put a small amount on the threads and torque to 13 lbf•ft. Is it possible that they say to use such a low torque because they already take into account the effect the Anti-Seize has on torque value?
While Honda may use different plug manufacturers it hard to be certain. If NGK, then Anti-Seize is not recommended. If NGK, please follow the torque specs in the back of the current NGK catalog or on our website here: www.ngksparkplugs.com/tech_support/spark_plugs/installation/index.asp?mode=nml#installing
There is something called wet and dry torque. has nothing to do with the plug itself that has to do with the threading and the material. Anti seize will absolutely not have an adverse effect on the plug performance whatsoever. This shit isn't rocket science anyone who knows anything about anything knows this. Some copper coat and away ya go nothing wrong with being able to break them free easily. same goes with wheel studs brakes etc... if you're smart and want to help eliminate risk copper coat everything makes your life easier when it comes time to take whatever out or apart and decreases the chance of snapping anything off. End of story bottom line...
Hondas repair manual specifically says Anti-Seize. And specifically recommend NGK or Denso. NGK being listed first and also the original plugs I pulled out of the car
ngksparkplugsusa, I have a 2000 ski-doo mxz snowmobile that occasionally backfires on warm startups. Does this have anything to do with my NGK spark plug spark gaps? Timing? what else should i check? Thanks.
hi i just got my tuned up and get a spark plugs changed. i watched my mechanic change my spark plug and i didnt see them adjust or anything they just install it just like whatever i asked them "dont you have to adjust the gap?" they answered me "no" because they use iridium and it doesnt require adjustment.. can help guys if i need to adjust them?
Hey, I would like to ask how you would know if your engine is misfiring as a result of plugging the spark plug wires in the wrong configuration? My dad has a 1995 Ford Explorer and the RPMs go up and down a bit about 200 RPMs when you first start it but you don't really notice it or it stops after about 2 minutes. Is that normal? I am just worried I might have plugged the spark plug wires with the wrong cylinders. Thank you.
@LennyCox Did I comment on that part? No, I'm just saying they're pretty stupid to mention why you shouldn't use a certain tool because it can damage the electrode and that's only the case because they're not even using the tool correctly! If used correctly, the coin gapper doesn't even touch the electrode tip.
@ngksparkplugsusa No it doesn't, it only demonstrates Opening. He SAYS "Open or close the gap" However, it shows him opening the gap, then rechecking it.
@emp0rizzle Seems as though you missed the portion of the video prior to that demonstration that read, "Gapping - Incorrect". Also, maybe you didn't listen to the guy when he said gapping plugs the incorrect way could break the plug, and if that happens you should throw it away. I believe he should have shown you the correct way to gap using a coin gapper though, not just the incorrect way.
This video tells me you don't know how to use a coin style gapping tool you don't use the groove to open the gap or close the gap on a spark plug you use the hole. If you use the whole properly you don't even touch the probe
I used a coin style because I didn't know better. However, I checked the coin with accurate calipers at the gap I needed. The coin was off by .002" too thin. The plugs all measured .029" on the coin, which means they were really gapped at .027". The target was .031" so the difference was .004". Or in other words, I had to get the coin to measure from .029 to .033". I checked .033 on the coin and it was .031", Ok? Therefore I had to open each one by +.004". That sounds complicated but I measured .033" with my calipers and that read .031",OK? I couldn't believe that they were all off by such an exact and consistent amount. Were they really off? What could be inaccurate about this? I should have sanded the coin smooth on the bottom, cleaned it, then add layers of packaging tape until it's accurate. Then it wouldn't be so weird. One plug had a tab that was much weaker, and my first push moved it way out. Then I pressed it back and was back to where I began. Why was that tab so weak? Will it fall off? So I'm concerned about that plug and also second guessing the coin measurer because there may be a .004" feature on the tab such that a flat feeler gauge would be off because that .004" feature is not lined up with the Ruthenium point, and the real gap is .004" wider, if read with a wire type. Maybe? I don't know. I'll have to look under a magnifying glass to see if I really need a wire type. If this is the case I'd really have to push each tab .004 back in? Maybe? Did they gap them to my car? I just don't know. There are some platinum plugs that require a .040" gap. Where did I come up with .031"? I thought I saw that on NGK. Now I question everything. I hate this about myself. It drives me crazy. If NGK could address this, my car is: 2003 VW Passat W8 wagon (4.0 L V8 engine) Hopefully, someone can straighten me out.
I hadn't changed the spark plug ua-cam.com/users/postUgkx-6W-PtUzBRTmACHywsECak2ToY2OpjxN in my Toro 20" Recycler in the 6 years I've had it but have been good with all other maintenance. This season I noticed it sputtering a little bit every so often and just didn't feel like it was running as smoothly or as powerful as it used to. Switched out the spark plug for a new one yesterday and could immediately tell an improved difference. So I may have to make this a little more regular than every 6 years, especially for a $5 part!
This video fails to illustrate the point when a proper gap is achieved using the tool. If you have a plug that needs 0.60 spec, then the 0.60 tool must barely have resist or a slight "grab" when checking. If the tool slides freely with no resistance, you are over-spec and need to close the gap and recheck for the slight contact.
So why do people who make these video's think it's ok to blast the music? I have to keep turning the video up and down. It's not necessary and it's annoying.
@chrisjeffsmusic I just smashed the trash out of my spark plug to close the gap. Don't be scared. Tap it like a baby. :) used auto lite double platinum
Kinda sad video. We all know basically how to gap a plug but since these new plugs are delicate I wanted to see a close up of the gauge and the fit it had between the electrodes. Another words just how tight/resistance was the tool to the electrodes. To be honest I mean if this is a video someone needs to watch before replacing spark plugs then perhaps it is best you let a mechanic rip you off.
You're gapping it wrong with the coin gapper. You're suppose to use the keyring hole, not the measuring side of the coin. The hole has a protruding lip that is suppose to be slid on the underside of the side terminal and then pried up to adjust the gap. FAIL.
To tell people not to use something that has been working for the longest of time (coin type) sounds like you are using scare tactics to sell this product, I will continue to use the coin type.
thanks, good to know i bought the wrong style gap check tool.. oh well.. Ill still get my $0.99 out of it carefully checking gaps, but not adjusting them.
Hey, where did you hear we don't recommend checking/adjusting the gap? Every plug should be inspected and checked for proper gap prior to installation. Mike Becker, Senior Technical Instructor
First off specifically you did not say which vehicle engine this was for and what Gap it was supposed to be set at for the manufacturer specifications versus what was the Gap out of the box shame on you you should be considering your audience assuming they know nothing about this subject?
argghhh horribly detailed!!! they doesn't tell me at all how to gap a spark plug, you need to start this video over. using the coin since that is most standard. what is the correct gap!!!! give give us an example! My question is, what is exactly .032? with the spark plug. just make another video its easier that way. we can use the coin gapper for copper plugs!!!
Those spark plug gapping tools SUCK, THEY BEND WHEN TRYING TO SET THE GAP IF IT IS INCORRECT. The one you showed after gapping sure a HELL WAS NOT RIGHT, LOOKED TERRIBLE.

I used a coin style because I didn't know better. However, I checked the coin with accurate calipers at the gap I needed. The coin was off by .002" too thin. The plugs all measured .029" on the coin, which means they were really gapped at .027". The target was .031" so the difference was .004". Or in other words, I had to get the coin to measure from .029 to .033". I checked .033 on the coin and it was .031", Ok? Therefore I had to open each one by +.004". That sounds complicated but I measured .033" with my calipers and that read .031",OK?
I couldn't believe that they were all off by such an exact and consistent amount. Were they really off? What could be inaccurate about this?
I should have sanded the coin smooth on the bottom, cleaned it, then add layers of packaging tape until it's accurate. Then it wouldn't be so weird.
One plug had a tab that was much weaker, and my first push moved it way out. Then I pressed it back and was back to where I began. Why was that tab so weak? Will it fall off?
So I'm concerned about that plug and also second guessing the coin measurer because there may be a .004" feature on the tab such that a flat feeler gauge would be off because that .004" feature is not lined up with the Ruthenium point, and the real gap is .004" wider, if read with a wire type. Maybe? I don't know. I'll have to look under a magnifying glass to see if I really need a wire type. If this is the case I'd really have to push each tab .004 back in? Maybe? Did they gap them to my car? I just don't know. There are some platinum plugs that require a .040" gap. Where did I come up with .031"? I thought I saw that on NGK. Now I question everything. I hate this about myself. It drives me crazy. If NGK could address this, my car is:

Hopefully, someone can straighten me out.
very detailed video
I hadn't changed the spark plug ua-cam.com/users/postUgkx-6W-PtUzBRTmACHywsECak2ToY2OpjxN in my Toro 20" Recycler in the 6 years I've had it but have been good with all other maintenance. This season I noticed it sputtering a little bit every so often and just didn't feel like it was running as smoothly or as powerful as it used to. Switched out the spark plug for a new one yesterday and could immediately tell an improved difference. So I may have to make this a little more regular than every 6 years, especially for a $5 part!
@MrSnakeaholic hahah lool just be careful i made custom tool my shelf it works fine !
I looked this up after reading that increasing spark plug gap on a honda civic by 20% can increase the gas mileage by up to 3 MPG, is this true?
This video fails to illustrate the point when a proper gap is achieved using the tool.
If you have a plug that needs 0.60 spec, then the 0.60 tool must barely have resist or a slight "grab" when checking. If the tool slides freely with no resistance, you are over-spec and need to close the gap and recheck for the slight contact.
Nissan Maxima 04-06
0.043 gap
Nissan frontier '02 3.3 supercharged what's the correct gaping? Please
thanks for the video .
So why do people who make these video's think it's ok to blast the music? I have to keep turning the video up and down. It's not necessary and it's annoying.
Sorry about that. I agree.
@chrisjeffsmusic I just smashed the trash out of my spark plug to close the gap. Don't be scared. Tap it like a baby. :) used auto lite double platinum
Kinda sad video. We all know basically how to gap a plug but since these new plugs are delicate I wanted to see a close up of the gauge and the fit it had between the electrodes. Another words just how tight/resistance was the tool to the electrodes. To be honest I mean if this is a video someone needs to watch before replacing spark plugs then perhaps it is best you let a mechanic rip you off.
You're gapping it wrong with the coin gapper. You're suppose to use the keyring hole, not the measuring side of the coin. The hole has a protruding lip that is suppose to be slid on the underside of the side terminal and then pried up to adjust the gap. FAIL.
To tell people not to use something that has been working for the longest of time (coin type) sounds like you are using scare tactics to sell this product, I will continue to use the coin type.
What if you can't find a gap tool the right size. .043
thanks, good to know i bought the wrong style gap check tool.. oh well.. Ill still get my $0.99 out of it carefully checking gaps, but not adjusting them.
@MrSnakeaholic i'll be careful !!
Possible
c povre en ostie vot affaire gagne de pion
Hmm but NGK recommends not to adjust gap, guess this is an old vid
Hey, where did you hear we don't recommend checking/adjusting the gap? Every plug should be inspected and checked for proper gap prior to installation.

Whats the best gap for 04 g35 rwd? Say for racing or drifting
That's not even how your suppose to gap a spark plug with the coin style gapper, of course your going to break the tip like that!!
First off specifically you did not say which vehicle engine this was for and what Gap it was supposed to be set at for the manufacturer specifications versus what was the Gap out of the box shame on you you should be considering your audience assuming they know nothing about this subject?
stop fooling with the sound volucme
Oops...
Ben. .
,
argghhh horribly detailed!!! they doesn't tell me at all how to gap a spark plug, you need to start this video over. using the coin since that is most standard. what is the correct gap!!!! give give us an example!
My question is, what is exactly .032? with the spark plug. just make another video its easier that way. we can use the coin gapper for copper plugs!!!
@abunaiN1 i just broke one.....lol
Those spark plug gapping tools SUCK, THEY BEND WHEN TRYING TO SET THE GAP IF IT IS INCORRECT. The one you showed after gapping sure a HELL WAS NOT RIGHT, LOOKED TERRIBLE.
