    I have a 2004 SRT with a cam, forged internals, Roe VEC3, Belanger Headers. What kind of spark plugs should I be using? The kind I pulled out are Champion RC12ECC, but they just seem a little cheap to me. Is that an OK plug to be running or should I switch to something else?

    Thanks,

    -Craig

    What cam are you running? I have the 710 cam from Roe and they suggested that I run Bosch Platinum +2 4308. When I was looking for them, they were discountinued but Roe racing had them in stock. They might be back in stores.

    I think that is probably the recommended one. Stock Champions. About $2 each?

    I'm thinking even a lot of the "boosted" guys are running stockers. If you're doing excessive drags and track driving, then the colder plugs might be recommended.
    When I was N/A, I ran the Bosch Platinum 4+. My car ran great on 'em. But many others said not too.
    I'm not sure about the Gen3 heads, but the Gen2's require the "L" plug. It's fit's a tad deeper in chamber. (someone correct me if Im wrong)
