Does anyone know what the spark plug gap is for the 2004 gto a guy told me at advance auto parts that it is .060 but isn't that too high? and I think it is suppose to be .044 right?

i have NGK laser platinum

Thanks

There was a thread on here somewhere that had the new gap for the GTO's because they changed from platinum O.E. to iridium O.E. plugs. Gap is .040.

Ngk Tr55 & Tr6 Are Gapped @ .035 But The Ones You Have Need To Gapped Between .035 And .040 But No Higher.

LS1 was originally .060 as was previous years. Mid year got a new plug and new gap, .040. LS2 uses this same plug.

NGK TR55 should be gapped at .050.
