Just verifying. I have a 4th gen 3sgte and I am about to replace the plugs with NGK bkr6egp and plan to gap them at .032. Is this right? I have searched and this seems like the right info, just wanting to verify.

That's what I gapped mine to. Others running higher psi than stock will want a little tighter gap like .028.
