+1 either should be fine. Haynes manual says .054, but if you buy oem replacements they are .052................or maybe vice versa

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.

It's possible.

I had the platinum 4s - like 5 bucks a piece - and the car idled like it had a vacuum leak. So I switched to NGKs and its been smooth ever since. Regap yours and let us know how it goes!
