plug surprise

I have read that spark plug gap on my 04 GTO should be around 0.60 so i pulled them and every single one was set at 0.35, so i will take her out in the morning and hopefully i will see and improvement in performance.

Keep us posted. Will look into that when I get some time. Thanks for the heads up.

If the stock plugs are ACDelco 41-985 the gap should be .040.The ACDelco catalog states (Iridium;Do not Deviate from preset gap .040 )
