Re: Which Brand of Spark plug do you run??
I'm sure that there are better plugs than the GM replacement for the FR2LS plugs. I just feel that buying the regular 61-402's @ .35", and throwing them out every winter isn't killing me cost wise. I would even believe that the 402's aren't really a direct replacement for the 2ls's.....but the 402's seem to work real well for 5k miles at least.
