Spark Plugs

[OnEbAdReDSS]

just wondering what kind i should get... should i just go to the stock plug from ACDelco?? but they are about 7 dollars a piece

Most of us use the NGK tr55. Part #3951. They're copper tho and will have to be changed every 20,000 miles or so. Only about $1.60 a piece. If you never want to change em again for a while I'd look to the NGK tr55ix. They're iridium and should last much longer, like $6 or $7 a piece tho.

I might be wrong, but I believe the Bosch Platinum 4+ plugs are pre-gapped from the factory for best performance.

i went with ac delco platinum, there is going to be no power differance between bosch ngk or ac delco, BUT if you plan on nitrous you need to put in copper plugs!
