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

Re:Spark Plug Help!
? i thought 7's were 2 colder than stock, you want bkr7e's for boost and gapped to 30
i learned the idiot way!!! why is it misfiring oh i am ------- stupid!!!!! |
Re:Spark Plug Help!
i probably have it backwards, i donno, i took my cover off with all that info under the hood, so couldnt tell ya

Re:Spark Plug Help!
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? |
Re:Spark Plug Help!
For my D16Z6 both my mechanic & a rep from Nology wires told me that the NGk-4554 is one step cold.

Re:Spark Plug Help!

Re:Spark Plug Help!
All the searching I did ended up with threads like this... 17 plugs numbers. ;)
I'll give the last one a try and thanks! |
Re:Spark Plug Help!
i dont have any reps but i can tell ya the one i have works great, no misfires, runs perfect at 6-11psi

Re:Spark Plug Help!
I've actually been told that stock NGK plugs (copper ones) gapped to .030 should sufficient. I'm probably going one step colder just to be safe. :P
