Ngk that are compatible with stock plug really. Unless you have crazy mods, you won't see any major difference from plug unless yours are bad

What did you end up going with? I say OEM if you're not heavily modded as well.

Speaking of spark plugs. Anyone know what the part number is for autolites that are 2 heat ranges colder than stock?

I going to try the OEM.....I guess the guy that had the car before me never changed them because they are black!!!! I guess any sparkplug will do good at this point!!!
