damn really? i think they are platinums im not 100% i know for a fact they are bosch tho. i basically just replaced what was in the car from the previous owner, cuz the auto shop was tryin to tell me i had to buy some ridiculous ass 8$ plugs that ONLY mustangs ran on....i was calling bullshit on him.! lol
my car runs fine, im just going off track results, i was running a 9.7 on the 8th mile, after i did, A CAI, wireset and plugs, and the recalled intake manifold. i was running 10's and up, so im thinking it could be from the plugs not being gapped right.
