Sooo heres the deal im gonna be running lucas 42s and gm stage 2 pulley with a custom tune. what spark plugs do i need to run? will stock be fine? or what step colder? i need a plug number and what they are thanks
ps its an 2007 SS SC 2.0 with the m62

 

NGK 1 Step Colder Plugs SKU: BKR7E

 

thanks what are ur numbers ur on the same setup ill be on ?

 

Yeah, I have 42's and a 3.0 pulley and those are the same plugs I'm using. They do help. Set the gap to like .0032.

 

i second that plug, they work very well

 

Don't use anything else. Stay away from the mystery plugs.

 

Got these on my Stage II as well. Definitely runs a little smoother

 

^^ on 42's and a 3.0 and ur running a that gap....

not saying it wont work but the norm is .40-.44 for 2.9+

 

That seems a little large. I find 0.035 works best with my setup. Hell, that's the gap my spark plugs game with from the factory.

 

You could use Autolite 3922's too. Copper core

 

That's the gap OTTP advises.

 

zzp and ottp say you should run a gap of 0.32-0.34, I think everyone just listens to them. It does seem a little low though.

 

correction 0.032-0.034

 

what gap do i need to run em at? seems to be some controversy over it

 

Well, my manual says 0.039, but my plugs came gapped at 0.035 from the factory. Also, my car came with iridiums from the factory even though the manual calls for platnium plugs. You need to mess around with the gap to find what works best for your car. A car that has a GM Tune runs best with the factory plugs. You really dont need 1-step colder unless you have a custom tune, and extensive mods.

*Correction you are getting a custom tune. I missed that part. Sorry.*

 

.035 and your done, this gap will work for everything for a 3.0 to a 2.5

 

I agree that 0.035 is best

 

yes pretty much .035 is a great gap.

thats weird that your car came with a gap of .035 as the factory setup should be ran at .042

 

I was getting my car dnyo'd at a shop here in pittsburgh, it happen to be a honder shop, I was getting really bad spark blowout, cause by the brand of plugs I was using, the hondah boyz were like what gap you using, I said 0.035, they were like WWWWHHAAA?! You gotta crush that thing down to like a 0.021 or smaller. Silly hondah boyz and there gt4076r turbo'd b18c1.

 

hah id be suprised if your car even started with the gap they were trying to push on you lol can u say running rich?

 

ya, i was like listen, my car isnt jumping off the rollers with 550+ wheel guys, also I learn how obd1 hondah boyz tune there afrs, think circuit board resistors

 

bkr7e's at .35-.32 i ran mine on .32 all the way up to the 2.7 and 60's it had before trade in

 

ive never looked into hondas much i just never really had the urge to learn about them. i have heard that they run high compression and tend to blow up under any good level of boost without something being done to the motor but i could be wrong about that.

 

honda makes a mean motor, b or k series, they can take alot of abuse

 

Factory plug gap for an 07' was 0.039. At least that's what the manual claims. 0.042 is a little on the large side for a forced induction plug gap. I heard some earlier SS/SC's claim the stock plug gap is 0.040, but i never heard 0.042.

I also found it weird that my car came installed with A/C Delco / NGK Iridiums rather than the platnium plugs as well as my 0.035" plug gap.
