what's the correct gap on spark plugs?

[Krist B.]

i'm trying to fix my car in order to pass emission test 'cause my car's got oxides of nitrogen (NOx) failure. i think i had incorrect gap on spark plugs, so what's the correct gap for our car?


(also, i still need to check on air/fuel mixture)

Well, if your air/fuel mixture is incorrect, then not muhc you can do about it. Your ECU takes care of all the mixture balancing.

But the correct spark plug gapping for the B series engine is .039 - .043

thanks for the help. but 0.39-0.43? so i assume 0.43 is for B6ZE, right?

[MX3-Freak]

the B6ZE is .039 - .043, the difference of .004 of an inch isnt going to make much of a difference. Hell, you couldnt get it that specifc without the help of a computer (a thousand of an inch is not visible to the naked eye...).
