Spark Plugs
 

so today i ordered 1 x NGK Iridium Colder Spark Plugs 08-10 Cobalt SS Turbo suppose to be 1 step colder plugs for us turbo guys who are running add ons or a tune with higher boost so the website says this is a good buy..

what do you think good buy or bullshit?

bump

3787"S run well, the 6509's are Iridium IX 1 step colder also (premium plug) but need to be gapped down to .032 carefully out of the box.

I have them in my car. Runs alot smoother across the RPM band.

how did you gap them? website says not to use a gapper but take a pair of needle nose and pull it open and i guess use the gapper to test it to see where it is but says should be gaped to 30-32

how do i judge where is a good gap and what to do?

Use the little hook on the gauging tool to adjust the outer electrode only. THe fine wire inner electrode & tip are brittle and crack easily.

1 range colder 3787's come gapped to .032 out of the box and run well.

5476 are the stock heat range.

just ordered...NGK (3787) ILTR6A-8G Laser Iridium Spark Plug, Pack of 1

Where can I get the pre-gapped Iridium's, I've been looking for awhile

I'd rather not try and gap them myself cause if I broke them I'd be pissed :lol:

So pre-gapped ftw

Believe it or not, Amazon has the 3787's.

I'm not a huge fan of amazon :lol:

I know I know

anywhere else?

I dont mind paying a little extra

got mine off amazon

^ Cool thanks

You will like the ! step cooler plugs, but why not go 2 steps cooler if your running 20Psi or more of boost?

I ran 6510's (2 ranges colder) for 10k miles with no issues or fouling but you have to gap them down from .044 to .032 out of the box. More than NGK recommends.

hmm i already order the first ones then per suggestion i ordered these 3787s im not gonna keep ordering plugs and be stuck with them all over my garage

You'll like the 3787's they are cold enough. I only tried 2 ranges colder to kill some knock retard but it didn't help.

i went with the stock oem plugs next time i will try the 3787's

Amazon had the best price when I ordered. All were gapped at a tight .032

yea so my fucken plugs come in the mail today all at once the ones i ordered the first time and the 3787s i open first box and its a box with all 4 boxes inside with plugs second box 1 fucken 3787 how the hell do they package the shit differently from the same company, so guess which ones ill be installing.

Not to be a douche but Did u order 4? Cause I think its 15$ per one right?

it's not hard gapping spark plugs guys.

If you can't gap spark plugs, you shouldn't be putting them in your car.

Even if they come pre-gapped - I still check them, regardless.

yea i found that out. and if you order them from the auto parts store they are 20 bucks each but you can get them in the next day.
