This trick works well on 1999-2007 Chevy trucks. I only use ACDelco plugs and wires on these trucks.

Same situation I have in my 2000 silverado 1500 5.3 ..I opened the gap to .060 like the truck says should be. I'm wondering if that was a mistake for me to do that or not.. so far no issues but it's only been a day..
@@LG-fb9ytI believe the .060" is for the factory plugs. Copper or platinum. The iridium (new/updated/better/different) should be .040 There is a reason they come pre gapped. Pull all your plugs out and ungap them by a .020" Lol
@Randomness984 I know that they don't believe the average guy is capable of realizing it's possible to fuck up the spot on the ground strap or the electrode when gapping them.. so they pregap them.. however the vehicle manufacturer specifically states 60 thou.. and if the coils are adequate to make the arc that far..wouldn't it be best to have that larger arc to allow better ignition etc as compared to the smaller and likely only marginally hotter spark. I mean on engines with weak spark one can run smaller gaps to have a stronger or more reliable spark..but that's to mitigate an issue.. what would be the problem with larger gap if it's not creating any problems initially? The truck seems to run as well as it ever has since I've had it..maybe better. Also it has 338,000 miles on it so far, has been worked hard before I got it, and plowed snow a few seasons..hauled wood and pulled equipment at times since, and has done a crazy amount of idling. I think the hr meter is not far from rolling over a second time..they only go to 10,000 hrs..then start over. It's amazed everyone who knows the truck and or previous owners etc. As for me..I wish I could find one just like it but new.it would last the rest of my life or more.
I replaced my 2003 Silverado's original iridium plugs with platinum plugs to save money on it's first bi-decade tune up. The engine was running ok, just thought it might be a good idea after 20 years to tune it up to get better mpg. After installing platinum plugs I discovered the original iridium plugs having 240,000 miles on them ran better. I replaced the new platinum plugs with new AC iridium plugs and the the truck never ran better. I will verify this video is true.✅
Thanks for sharing. This is why I'm sharing this info with everyone. The Iridium plugs really make a big difference. I wouldn't waste time with platinum plugs. I always notice the best performance with ACDelco Iridium plugs in these trucks.
Dumbest thing ever heard in my entire fkn life smffh u can use copper core champions no problem long as all plugs are the same smfh no copper plugs last 100k smfh there 2 bucks a pop not 18 and coppers are good for 30k miles or so.
As far as I know, NGK produces the AC Delco spark plugs sold as AC Delco. The NGK cross reference: AC Delco 41-110 ->NGK iZTR5B11 This plug is equipped with a 5k ohm internal resistor and the heat range is 5 Always make certain to use the correct plug, compare them physically (length, thread diameter and pitch, etc.), to avoid damaging your engine!
Most people that acquire 150,000+ on their vehicles are more concerned about cost than another 150,000+ miles on it. In many parts of the country the body, frame, and suspension will be rusted away before the 2nd set of plugs will wear out. 2000 Ram with the V10 used for towing which can cause earlier plug wear had 2 spark plug replacements with very little wear on any of them. There was no power or fuel mileage change when replaced. They were the copper core and this was original. At 260,000 miles and 17 years I traded it because it was so rusted out the door latch strikers rusted out of the posts and I had to tie the doors shut. Engine and drive line where still going strong and compression at last plug change where all even and in spec. Oil pressure was less than 5 psi lower than new. The point is sometimes over kill is just wasted money with no other practical gains.
As per your previous video, I had purchased the ACDelco double platinum plugs for my 06 Tahoe last spring. I installed them a couple weeks ago with the double platinum. But since replacing the plugs on my 93 Astro a few days earlier, even that #8 cylinder on the 5.3 was not at all hard to do.
HA HA I put AC Delco 41-101 Iridium Plugs in my Olds Alero and cannot believe the power and response from that 2004 engine. Also, had the same success in my 2006 Ford Explorer. Well worth the price for these plugs. Also love that they are pre-gapped.
Here's a pro tip if you don't want to remember the serial number. Just ask for the spark plugs for an 05 or 06 vin B engine. That is the rare aluminum block H.O. 5.3, it comes with iridium tiped plugs stock. I know this because I swapped an L33 into my tahoe and got iridium tips without knowing the difference.
There was a TSB that said to use double platinum 41-962 on 99-2006. Also some 2007. Iridium is fine, but not necessary. 2007+ need iridium. “ACDelco announces that 2006 and older, as well as some 2007, spark plug service applications covered by the iridium spark plug 41-110 have moved to the platinum plug 41-962. For the older model years, GM used a double platinum spark plug in production, and these older applications are to be serviced with the double platinum plug 41-962. 2007 and newer applications used iridium plugs in production and service requirements will remain assigned to the iridium plug 41-110. Both plugs meet original equipment specifications for the applications designated". There ya go.
there PLUGS used to show up. USED TO I used them in a 06. Lookup maybe a 08... 5.3 might show correct at a store. The old GMT 800s will run to 500k or more
I put copper delco plugs and omni spark wires on my 03 Lt, 30k miles later running absolutely great. thats what i like about these trucks, they are not fussy about parts. If i noticed a diffrence in performance i would put the best, but i also own many vehicles including project vehicles so I put standard replacement parts. Even oil I use supertech synthetic blend with a supertech filter with half quart of lucas. Really cold winters up north.
Your videos are a great help man been helping me fix up my 03' Silverado for a while. Got any tips on why my truck would be throwing a P0300 code AFTER replacing the plugs? I got the ACdelco 41-962s and ever since I've been getting random misfires on all cylinders. Mechanic said the engine may be worn but I just don't think so. Too much of a coincidence.
I found that the gap was way off and had to go to 4 different stores to find a full set of properly gapped plugs. Went through so many boxes and only bought a few from each store. They say they are pre gapped and cant be adjusted beware of just buying a set and installing without checking first
Matt chasing loss of coolant overheating for a long time ! Have replaced clutch fan , thermostat and several coolant flushes.!still will lose coolant slowly over course of coupe months or overheat idling for long time . Need your advice /maybe video on overheating ?
WOAH. I am working on this right now on the red truck right now. It is not easy to fix I have some videos coming on it. Check the plastic heater hose connections first where they go into the firewall. They always leak!
@ yes it been tough .. it actually started with those heater hose connectors … they were 22 years old and just destroyed . I replaced them as that was initial leak. Been chasing this problem since then . By the way, you have a great way of teaching in your videos .. they have helped a lot .
It’s most likely leaking from one or more cracks in the cylinder head(s). Remove the valve covers and pressure test the cooling system. You’ll see coolant seeping from cracks in the castings.
If it’s the porosity in heads… then is only solution new cylinder heads? It’s that or coolant flushes 3-4x a year. Also, would the ac delco coolant sealant packets help/worth a shot? It’s an 02 suburban and thanks for your help !
I would call the dealer and ask for the latest Iridium plugs for that truck. Honestly, it's so new I'd leave it alone until it's time to change the spark plugs. It's a 2022 I don't know what it has in it from the factory.
Do the old part number spark plug wires matter? I know the dealer updated the part number on the wires to where the part stores claims the new number is for later models. If we put it the old model wires, will performance suffer?
Spark Pugs: OLD 41-985 NEW 41-110 NEWEST 41-162 Plug Wires: LONG: 9748HH SHORT: 9748GG The best combo I run is these plug wires and the 41-110 or 41-162 and you should be alright 👍
Hey I found a plug that's better than iridium plugs... it's a ruthinium plug. Can be found on rock auto's website they are a bit pricey on the site but far cheaper than at the box stores. They are a new type of plug and they are really good, I have them in my 98 sh!tbox immediately I noticed better mileage and power will NEVER go back to AC Delcos again, anyway just wanted to let you know about them plugs
Hey man i have a 4.8 vortec 2006 and i was wondering what high performance oil pressure you recommend or if you would even recommend? im also thing about upgrading the transmission oil cooler and wanted to see what you have in mind????
Hey Matt I've heard of the 41-162 coming out the box looking dirty and "fake" have you heard of this? Alot of people say the good old 41-110 work way better than those 162's.
Everywhere I go or look they keep saying my 2000 Chevy Silverado with 4.8 4x4 takes spark plug 41-962 will they work or is it better to get the 41-162 although I can't seem to find 8 of those in stock
@@MattsShop okay awesome man thanks! Will the right part pop up when I give them the info at the store? (Only asking because the ones in your video didn’t pop up in the parts store computer lol)
I do not know if it does for the 4.3 V6 if 41-985 fits the V6 then 41-162 should fit them too. I doubt it will work with this part number. There is probably Iridium plugs for the 4.3 V6 though.
Wife and I have 3 of them all have 200k plus 2 of them are 03 and an 05 one has 400k we only use factory plugs run perfect on them we do mechanic work and only recommend factory ones in them
@user-wj9wq7mk4h if they're only oil fouled just torch them to burn all the oil out of them that is down inside.. heat then up good enough to get them glowing where the threads are.. you will see what I mean.. after the threads are glowing well let them cool check gap, ..install them and they should run like new. Saved hundreds on sparkplug for 2 strokes that way over the yrs
I cant tell you 100% for sure. I am not as good with the newer trucks. I know the most about 1999-2007 Classic trucks. I would look it up online, but I know there has to be some Iridium plugs that will fit.
Misfire @startup MIGHT be the fuel pressure regulator failing. Also check the elbow vacuum line from the fuel pressure regulator to the top of the intake on BOTH sides of the hose
Does those spark plugs fit 2001 Chevy Tahoe 5.3 litre 2002 Chevy Silverado 5.3 litre 2005 Chevy Silverado 5.3 litre Does Not Fit 2001 Chevrolet Tahoe, Sport Utility GM Parts websites says it does not fit.
That's the whole point of the video. If the spark plugs are physically the same, they will work. This works on 4.8, 5.3, 6.0 Vortec V8 engines. I don't recommend it if you are not comfortable running the spark plugs in your engine.
It would be helpful if you could actually pronounce iridium correctly, lol. Additionally, longevity is only one part of the equation... actually, copper-core plugs give the "best" performance, you just have to change them more often (every couple years) and they only cost like $2 apiece. When choosing plugs... you're making a compromise between performance and longevity, you don't get both. The more exotic metals reguire more electrical current thus putting a higher strain on your coil(s). They last longer because they are harder (not as conductive.) Like I said, everything is a compromise of some kind. You're compromising cost and performance for longevity. The "best" plug for you might not be the "best" plug for everyone when ALL things are considered. You're leaving out substantial parts of the equation with your assessment. A better video would communicate all these factors so a person could make their own decision. You didn't include all the information necessary for a person to fully understand the decision of which plugs to use for them. Any type of plug will work just fine in these engines... but one must consider longevity, cost, performance, etc. when deciding which type to get, not just the longevity... all the factors need to be weighed together. So just because iridium plugs last longer doesn't mean their better in every category, just the one. If you were to do dyno runs with iridiums and with copper-cores, you'll make more power with the copper-cores, that is un-debatable, every racer knows that. Copper is a vastly superior conductor, it's just softer. For some people, they might be ok with spending only $16 every couple years on plugs, it's not that big of an issue to change them on these rigs... it's really rather easy.

Just did my 2002 suburban 1500. New plugs and wire. #1 and 8 were miss firing now she runs smooth with only 300,000 + miles.

@user-wj9wq7mk4h if they're only oil fouled just torch them to burn all the oil out of them that is down inside.. heat then up good enough to get them glowing where the threads are.. you will see what I mean.. after the threads are glowing well let them cool check gap, ..install them and they should run like new. Saved hundreds on sparkplug for 2 strokes that way over the yrs
Question: I have a 2007 however, it wasn’t the “classic” style it was the new style that wasn’t cat eyed, do you think it’ll be the same plugs?
I cant tell you 100% for sure. I am not as good with the newer trucks. I know the most about 1999-2007 Classic trucks.
I would look it up online, but I know there has to be some Iridium plugs that will fit.
They are still an LS based motor and should use iridium. It might be a different part number than they 99 to 07 classic models.
Is this why she misfires when she first starts up and once she's nice and what not everything is good?
I put in the platinums which I've never done I'm a carb guy Im used to copper only
Misfire @startup MIGHT be the fuel pressure regulator failing. Also check the elbow vacuum line from the fuel pressure regulator to the top of the intake on BOTH sides of the hose
Would a performance or good brand plug wires be good or make a difference like msd or Taylor?
I never really used them on these everyone says ACDelco. Those performance wires worked awesome on the old Chevy 350.
Already knew....
Does those spark plugs fit 2001 Chevy Tahoe 5.3 litre
2002 Chevy Silverado 5.3 litre
2005 Chevy Silverado 5.3 litre
Does Not Fit 2001 Chevrolet Tahoe, Sport Utility GM Parts websites says it does not fit.
That's the whole point of the video. If the spark plugs are physically the same, they will work. This works on 4.8, 5.3, 6.0 Vortec V8 engines. I don't recommend it if you are not comfortable running the spark plugs in your engine.
It would be helpful if you could actually pronounce iridium correctly, lol. Additionally, longevity is only one part of the equation... actually, copper-core plugs give the "best" performance, you just have to change them more often (every couple years) and they only cost like $2 apiece. When choosing plugs... you're making a compromise between performance and longevity, you don't get both. The more exotic metals reguire more electrical current thus putting a higher strain on your coil(s). They last longer because they are harder (not as conductive.) Like I said, everything is a compromise of some kind. You're compromising cost and performance for longevity. The "best" plug for you might not be the "best" plug for everyone when ALL things are considered. You're leaving out substantial parts of the equation with your assessment. A better video would communicate all these factors so a person could make their own decision. You didn't include all the information necessary for a person to fully understand the decision of which plugs to use for them. Any type of plug will work just fine in these engines... but one must consider longevity, cost, performance, etc. when deciding which type to get, not just the longevity... all the factors need to be weighed together. So just because iridium plugs last longer doesn't mean their better in every category, just the one. If you were to do dyno runs with iridiums and with copper-cores, you'll make more power with the copper-cores, that is un-debatable, every racer knows that. Copper is a vastly superior conductor, it's just softer. For some people, they might be ok with spending only $16 every couple years on plugs, it's not that big of an issue to change them on these rigs... it's really rather easy.
