Well the car had been runing like crap and it was like it would pull timeing just driving around.

I pulled them out nad Holly hell! they where solid black! My car has 5,400 miles on it.

I cleaned them and re gaped them. They where set at .035 and I set them to .042 and put them back in.
The car starts faster, runs and idles smother, and it has more power!

It runs beter then stock now and I dont seam to be runing as rich as I was.

Any one els done this?

I was having miss fires with the stock plugs. Pulled those babies out and wow they where horrible looking. I actually took it to my incompetent dealer first and they blamed the miss fires on my intake. Anyway, I swapped the plugs out with a set of autolites and boom problem gone. I now have NGK copper plugs gapped at .40 and am running super smooth and happy.

 

I have them on order^

i am gonna pull my stock plugs and check them, i have around 5000 miles, and the car is starting to idle rough

 

What mods are you running?

 

what should the BKR7E's be gapped at? stock gap.. like .045?

what is the advantage to a higher/lower gap?

 

Not much for power.
GM stage 2. A catt back and air box mod.

right now my bkr7e's are gapped at .045, ive got stage 2, intake, exhaust, gmpp exhaust manifold and 2.85 zzp pulley, cars runs awesome, im gonna regap them to.040 and see if there is a difference.

 

The NGK copper ones? where did you order them?

 

They wouldn't be so black if GM didnt detune the **** out of these cars, and make them run so damn rich, yeah I just picked up some NGK copper plugs good deal.

 

I think I might pull mine just to check them, as my car feels like it is running rich as hell, and it stumbles at idle some times

 

Yeah my stock plugs looked kinda shitty when I pulled them, I'm gonna try re-gappin them today or tomorrow (brk7eix's)

 

I pulled mine out a couple minutes ago. They didn't look too bad at all. However, the BKR7#'s I put in looked much better!
