what spark plugs?
 

Hey everyone I was wondering what spark plus do yall think I should run on my 94 civic coupe with the D16Z6 pushing 5-7 psi! Do yall think I should get 1 degree colder plugs? Well lemme know what yall would recommend and please give me a part number with it! Thanks for the help! Nick


Right now im running regular ngk v groove plugs!

Hey i just researched this myself yesterday. I would go 1 step colder, but make sure you need them first b/c for 5-7psi you may not need them. Just check you stock tips for detonation. If there is, then get colder plugs

Here are the part numbers

1 step colder....NGK ZFR6J-11
2 step colder....NGK BCPR7es or BCPR7es-11
NGK(3330's)

do you know if those are pregapped?

Re:what spark plugs?
 

I think they are, but I gapped mine anyways just to make sure.

Re:what spark plugs?
 

theyre gonna be gapped for a stock motor, you will need to close them slightly i would think, more if you up your boost

Oops my bad... My motor is stock right now, but it will be boosted soon. :)

The -11's are pregapped, and the one's without the 11 are not.

That's how u can tell. GL!
