Thanks for the info! I used what I had (Coin gap tool). But yes your correct it's best to use feeler gauges. I was pretty careful not to damage the iridium tip
Everyone saying the plugs come pre-gapped😂 Okay, you go ahead and trust them... I never do and always find at least 1 that's off. These are the same people that get an oil change or tire work done, and then can't believe they had no oil or why the wheel fell off.🤦♂️
Ok, so I'm SO sure BOSCHE pre gaps their plugs wrong, right? Lol. Hey man, try some BOSCHE platinum iridium fusion 4 plugs. Pre-gapped, bet you love them, car instantly runs better, more hp, better mpg ..
These are the worst and most inaccurate 'gapper' that you can use, they sell for 50c for good reason mate.. even cheap feeler gauges would be far more gentle on the centre electrode which can easily be damaged with these cheap round gappers. I get what you're trying to do, but thats a bad tool to use and may cause damage, a cracked centre electrode may only show itself 10,000 miles later so its not always obvious the gapping is the cause.
Agreed, I was showing a cost effective option...the whee gaugel can be rough on the electrode if you don't have finesse. I would definitely recommend a gap feeler gauge pack or a legit sparkplug gapped. I was demonstrating with what I had for diy work
Check your plugs first, if they smell like gas, your running rich, also if it smells like burnt oil and have deposits on them...check your valve cover gasket. And run a fuel system cleaner
Little tip to everyone: if you turn the coin style gapper upside down and pry with the flat back of it (using the body off the plug above the threads), it keeps it off the iridium electrode while you're gapping
BOSCHE (an extremely reliable company, trusted by every supercar manufacturer) iridium plugs come pre-gapped according to model. They do this because YOU NEVER USE COIN GAPPERS ON IRIDIUM PLUGS! The majority of the iridium is on the two contacts, it's thin, and coin gappers can damage them.
Not always, I don't assume anything. I always check and adjust as necessary. Gotta take precation with Irridium not to mishandle the electrode tips. See the manufacturer instructions.
Not too informative of a video but i digress. Those old plugs were not fouled out. Fouling is when there is a layer or long track of carbon that shorts out the iridium pointy electrode to the ground way below the ceramic insulator. This shorts out the spark/arc that you would need. You can use that gapper tool but use the small hole to open up the gap as needed. This is to avoid cracking (including invisible micro cracks) of the very hard iridium. Its hardness helps it wear slower, lasting longer than alternative materials. Press the top ground electrode gently against any firm surface to close the gap some. When measuring gap, use the lightest force possible to find the gap. Gap size can be within about +/- 0.002”. Often a worn plug that was spec’d to 0.030” will start to misfire around 0.055” on stock ignition coils. You can just tighten the gap in a pinch. The gap is generally spec’d based on cylinder pressure/compression and repeatable ignition coil current (quality). The highest gap within a reasonable wear tolerance is usually the goal. This helps with emissions, smooth power/idle and fuel efficiency. Boosting to 15+ psi can require the gap to often be tightened to 0.018-0.022” prevent flame blowout from highly turbulent air-fuel mixture
Really? I've known that decreasing gap gives the plug more service life and decreasing gap and colder plugs are great for boosted applications. I've tried decreasing gap and my plugs run hot and melted 2 of my plugs. I've seen more complete combustion and better power delivery increasing gap by 0.002 gap
It always depends on the application. And yes you are correct in a boosted application. For example with my car 08 335xi it’s recommended to decrease gap .002 every 50 hp you gain I believe
@@Sonic86 Service life depends on what deteriorates within the plug, be that the electrode or internally. Service life is service life, a closer gap will just let you abuse them longer but plugs aren't expensive enough to be saving money on by wasting petrol or performance.
@@ScottyPilot agreed. I have set service on plugs. And with the application I run +.002 gap helps with more of a complete burn and I get better performance and gas mileage at the cost of replacing plugs more.
Depending on your vehicle and what spark plug you used...it matters. Usually from spark plug factory's gap is around .026 gap which is tight...itll last long but you wont get the spark performance and gas mileage as would from an oem gap setting. Think of it this way smaller spark gap>smaller combustion in turn=less power and gas mileage, oem to +.002 gap over will>bigger combustion in turn= more reliable power and better fuel mileage. Only down side to doing .002 over oem gap recommendations is shorter spark plug service life.
@@Sonic86 thank you 🙏 I used same spark plugs these ngk ones on my Audi A4 05 and didn’t gap at all so it’s taking few cranks to start but when it starts it runs perfect?
@@thotlord3086 yeah, I'd definitely gap the plugs to oem gap setting, Audi's are finicky. Look in the owners manual under specifications. Usually audi plug gap is .034-.036 gap. And I'd gap those spark plug especially if it's a turbo model👍
Actually these plugs were clearence for $20 on rockauto. Plus #3 & #4 pluhs needed to be replaced since the spark plug gasket from the valve cover was leaking and alot of oil was seeping into the spark plug ports and doing damage to the insulator
What does that mean?...am I a hack to you? I offer quick diy advise with people in a pinch and use whatever maybe lying around to get the job done. Not all people can afford real tools
It means you don’t even know how to work on your own. That gapper looks brand new as well. Take your stuff to an actual shop please. I’d hate to see you lose more money than you need too lmao!!!
Are we gaping fingers or plugs?
Seeing 👀 alot of Fingers at the end
They make tripod mounts😂❤
Never use a coin style gap tool on iridium plugs. It will damage them. You need to use a feeler gauge with iridium plugs.
Thanks for the info! I used what I had (Coin gap tool). But yes your correct it's best to use feeler gauges. I was pretty careful not to damage the iridium tip
Correct, as with most iridium plugs the contact points are the only iridium, and they're thin. Never use metal spacers.
Those old ones look great, definately not even close to being fouled out lol
Agree, I bet they all fire just fine.
Nothing wrong with old one's.
Everyone saying the plugs come pre-gapped😂 Okay, you go ahead and trust them... I never do and always find at least 1 that's off.

@@Sonic86 cost effective in this case would cost you more money
Except with what I had...a coin gauge and out of the box was @.022 when factory oem gap so for .028
Best way to ruin iridium plugs is with that gapper, only use feeler style.
Yeah a feeler gauge is best, I was showing how to diy gap with what you have when your in a pinch
How would a soft pot metal cheapo gap tool ruin it , but a harder stainless feeler not?
The edge is just to measure, not to size...
I think my car is misfiring at idle because im not running riduim plugs
Check your plugs first, if they smell like gas, your running rich, also if it smells like burnt oil and have deposits on them...check your valve cover gasket. And run a fuel system cleaner
The wrong plug might be the cause. Some engines won't run properly with a plug that's not exactly the same number and brand as original.
Little tip to everyone: if you turn the coin style gapper upside down and pry with the flat back of it (using the body off the plug above the threads), it keeps it off the iridium electrode while you're gapping
How do you know how much gap to use ?
Ngk Iridium come pre gapped for whatever application you buy it.!!!!!
When I opened the packages all the plugs were @.022 my oem application is for .028...
1 out of my 4 was way off, I ALWAYS check them...

Its seems no one knows how to use this circular gapper,,, the hole in it is used to bend the ground strap the ascending ramp is for measuring

When smoking crank go's wrong
Get it right....when smoking cr@ck goes right...bahahaha
Its fine too check, but you'll fuck these new plugs up easy by doing em like that. It won't be an obvious thing, but your ecm will knew the difference
They are pregapped at the factory. You're goong to damage the iridium tip
When I checked before I installed the plugs was @ .022 my application was for .028 oem
Iridium plugs are already pre gapped for you application. Iridium plugs can be damaged fairly easy fiddling with them like that.
When I took the plugs out of the box the gap was @.022 my oem gap calls for .028
I always seem to get plugs that are "pre-gapped" wrong. You should always check them.
@@cumshot247 exactly the plugs I got were around .022 so they were off .06. Always check the plugs I before I install them
Actually if you have more hp then stock you want a smaller gap. Not always good to increase gap.

I use needle nose pliers That way you don’t damage the tip.

Dude please don't work on anyone's vehicle, I don't think they can afford you bro.
