    Spark plugs for S/C

    TRD recomends a colder plug. I called them, they said thats for most people that can only get 91 octane, where as I run 93. So, in theory, the stock plugs should make more power, correct?

    good point. Im not sure about that. I run 93 over here in Italy also and seriously doubt I'll go back to my stock plugs.

    I doubt you'd see much of a power difference..but I'd think it's worth losing 0.582hp for peace of mind. :p

    hehe yeah, run a colder plug for 91 and stocks for 93 (if you're boosting) it helps with some ping & knock. lol

    just so you guys know..... you really should go with a copper core plug on a boosted motor...... plugs like platinum can crack in boosted situations, then you end up with platinum (or whatever) bits in your motor.....
