Your car is still "basically" stock, nothing internal has been modded. You will be fine with the stock plugs, or the 55's. The TR6's are what we will run in "cammed" engines, I run the TR6IX's in mine. The 7's as risingson runs are for the SC builds. And I'm pretty sure the guys will agree on all this. Hope this helps.
