Spark Plugs ?? I bought a set of NGK TR6s off a guy for cheap....my motor is basicly all stock except for a few bolt ons. I'm pretty sure these are 2 ranges colder than stock am I correct? Also, is it OK to run these colder plugs in my car or will I suffer any bad side effects?

Whats up Brad. Well, all i know is that the TR6's are for forced induction. Youd prolly want to run the TR55's. Unless you plan on spraying or going FI.

Yes TR6s are colder than stock..... only one heat range though if I recall correctly. I've known people to use them on NA setups with higher compression or to clear up issues with knock retard.
It's not going to hurt anything to use TR6s (Guys using these plugs because of N2O aren't spraying 100% of the time, but the plugs are still in the motor 100% of the time), but they will not last as long as the TR55 though, being a colder plug they will need to be changed more often. TR55s should be good for 20-30K miles, while people I've known using TR6s usually change them after about 10K.
Point is, you could use the TR6, but for your setup I'd stick with the TR55s. I've used TR55s in my '98 and '00 and I've always been happy with them.
