The plug should be ok if they are for your engine. You should set your timing back to stock 10 degrees while running nitrous. Gap your plugs about .032 - .035 and you should be fine as long as they are not platinum plugs. I hear nitrous and platinum plugs dont mix. Hope this helps

3925 is about the stock heat range.. 3924 is one range colder. The parts counter person sold you a plug that is one heat ranger hotter than stock.

I would return those plugs and get some 3924s or 3923s..

You want 3923's for aluminum heads. Set timing to 8-10*.

i think he asking what is the STOCK spark plug, get some autolite 24's or 23's if they make a 23 since 25 is the stock heat range.

I've got some 3922's sitting in my tool box, they're brand new and would work awesome for nitrous. AFR suggested 3924's as the starting heat range, and I went two steps colder for my nitrous set up. I bought these as a spare set. If you want them, let me know soon cause I have them on ebay, and I'll cancel the auction for a Stangnet guy.

Just re read the post and saw your asking about a stock car. You want autolite 23's.

Nick, you have a set of $10 autolite spark plugs on Ebay?
