A friend and I recently put new plugs in my car and gapped them to .042. I have seen everyone else posting that they have their gaps at .032 and I began to wonder if I should change mine. He says .042 is what he has always gapped all his plugs to on his supra(s). :scratch:

What car do you have Turbo/Non Turbo?

If it is turbo you would want it .032 if it is running lower boost ie. 13psi or lower with stock CT-26

.042 is N/A territory.


Thanks

Turbo (CT26) with the boost up. I have an intake and an open 3" downpipe. He drives an N/A so maybe thats whats up...

I actually said thats what the book called for, which it is. I haven't had the silver car for a long time and I didn't put those plugs in it when I DID have it. :)

I think I actually gapped mine at .029 (Turbo) since I saw this somewhere on the forums.

smaller than stock setting is usually best for higher boost on stock ignition.

That gap is to big.

Personally I wouldn't re-gap plugs once they have been used, buy new ones.

Why is that? I gap plugs all the time after use, especially when my brother steals the Iridiums out of my father's car so he can go to the track.
