I am trying to replace my spark plugs on my o4z..what is the oem plug and part number please? I looked up 100 different part numbers and it keeps changing..wtf.
i just ordered those...the dealer only has this number is 41-162 and they are$11 each..
FYI, you can get those same plugs from Summit Racing for $7.99 each and there is a $3.00 per plug mail in rebate available through 08/31/19 for them. https://www.summitracing.com/parts/ado-41-162
I ordered these from the guys over at CULTRAG Performance - they were super helpful and got them to me in 2 days. I got the GMPP wires from them too - see below for all part #s:

amazon is saying the 41-110 doesn't fit my car 2003 z06
Sometimes Amazon is wrong. Not sure this is one of them. GM and ACDelco list the 41-162 as the replacement for 41-110 in pre-2014 vehicles. No idea why, since the 41-110 and the 41-162 are iridium. In that case the iridium wins, with lower voltage and longer life. I just went with NGK to make it easier...
I believe the 41-162 replaced the 41-110. I just installed the 41-162 today, which I purchased through Amazon for $7.49 each. I also completed the $3 per plug rebate on ACDelco's website.

i checked 41-110 and 162 for the gap and its the same..not sure what the difference is?

I posed this same question to C4/C5/C6/C7 Specialist Paul Koerner and his reply to me was this: "The story is ACDelco is wrong from a technical aspect.
They are doing it for pricing so that they will sell more plugs at a cheaper cost.
41.110 is the ONLY plug I put in any LS1 LS6 LS2 LS3, applications for LS7 and LS9 are different.
All the best, Paul "
Paul seems to know his stuff so I'll take his word for it !
Hmmm, the 41-110 are cheaper than the 41-162... Great, I installed the 41-162 because all the sites, including AcDelco, showed that to be the correct plug but now I'm wondering... I know the plug Gap changed and I originally thought that was the difference, but someone here said it's the same on both plugs.

So confused. I need plugs and wires for my 02....I think. I only have about 36,500 miles on her but the plugs and wire are original. It has to go into my trusted mechanic for an alternator change so I figure why not do a plug and wire change at the same time. So....do I need to replace them? If so, which part number for the plugs? 41-110? EBay has them for $22 for a set of 8. If you get a $3 rebate for each plug, I'll end up $2 ahead. Something doesn't add up
I just replaced my plugs and wires this weekend on my 2000 with 68k on the car. Both looked like they could go another 30k easily. I really wanted them to be worn and brittle like Froggy's so that all the pain my son and I went through to change them wasn't for nothing...I have a post about it here: https://www.corvetteforum.com/forums...s-a-flyin.html
