Spark Plug Help!

I've searched and searched and searched and get about a dozen different answers for 2 steps colder plug numbers. I don't trust the ---- stains at my local parts place and want to give them a number instead.

I know the factory NGK is ZFR5J-11 (or something like that). Anyone know what the 2 step number is?

Any help is GREATLY appreciated! Turbo (and plugs) go in Thursday night!

Re:Spark Plug Help!

i think 7's are stock plugs on a sohc, but not exactly sure, im using zfr6f-11's, which is only one step colder, gapped to .030 and i have no misfires on a d16z6, and ill be changing them along with my oil this weekend, so i think the aformentioned 5's are 2 steps colder than stock, but unless youre running like above 10psi, i dont think you need to go 2 steps colder, just my opinion

Lower gap size = Colder Plug

Re:Spark Plug Help!

This is absolutely no help...

I don't know what boost I will be running as I am not set up just yet and have no idea on the wastegate actuator. I have a Turbo Xs boost controller on hand just in case though and will attempt to go up to 8PSI.

1 step colder then?
