Correct Gap?

Alright guys i did the plug and wire change. I bought the car last year so i figured i would change them so i knew they would be good. I had ngk tr55's in it that were gaped at .062. The previous owner gave me some TR6's so i decided to put those in. And on the box it says to gap to manufactures specs. So i gaped them to .060 and threw them in. I did some research and everyone says to gap them at .03-.038.

DID I GAP THEM WRONG????

the car runs and drives great by the way!

Thanks for the help

No change at all in any way.

It just doesn't seem to matter. It seems to be important on high boosted set-ups, nitrous and big HP engines.

Do them at .055 and you'll be perfect.
