platinum or copper spark plugs? my dad fouled one out on my ss yesterday that *******. he was doing 25 in 5th gear. so i was just wandering cuz its my first car and ive only changed the spark plugs on my ATV

 

I am getting copper tipped plugs for mine only because I am putting on a 3.25 inch pulley and the SFPH recommended those plugs for that mod.

 

Are the plugs the only upgrade required for the pulley? Do you have to reprogram the PCM or anything like that? How much more power to the wheels are you hoping for? thanks zin

 

go oem spec, they are actually the best for the cars, buying more expensive plugs will actually hurt performance, unless you are heavily modded, but im gonna guess ur not

 

Depends on the pulley size. For the 3.25 they just want cooler plugs to prevent keep down the heat. Anything less than 3.25 and you need to start messing with the computer I guess. I haven't put on the pulley yet so I can't say for sure.

 

I have a 2.8" pulley on right now.

 

NEVER use platinum plugs with a SC car. GTP owners have had bad results with platinum plugs.
