I was always told you should not run a platinum plug for nitrous. I dont remember why..... Does the same thing hold true for boost?

Just picked up a set of autolite platinum 103's with the intention of gapping them at 0.035".

Should i return them or am i ok?

 

I'd stay away from platinum. The material is too soft so any kind of hot ignition by itself will eat it away pretty quick leaving you with a nice big gap. Boost or nitrous doesn't do them any favors either. You have the gap right though. The prefered plug seems to be the NGK TR6.

I read up on it last night. Im going to return the plugs..... copper disipates heat faster then platinum.
