What is the gap for a the NGK BKR7E plug??? I just replaced my plugs and the old ones I had were set at 0.040. I have a GM stage 2 with AEM intake and a pulley boys 2.8"

 

Actually thats a good place to start. .40 Gap

 

If you have a 2.8 i would gap them at 34-35. I have a 2.7 and i gap mine at 32-33.

 

Yeah, he's probably right. I forgot that the reason i haven't had any problems with my Plug gap is because i haven't ripped on the car since i installed the clutchmasters clutch early last summer. Actually i'll probably go change my gap tomarrow while doing my Downpipe installation.

 

If you can't figure out the gap and the car is runnin shitty try some ZEX 82003-4 plugs. They are pre-gapped to 0.35 and are a tri-electrode copper plug. I was having problems finding the right gap and someone recomended these to me and all I can say is WOW. Me car loves ZEX. My mods are similar.

Stage II 42.5 lb injectors, CM stage 4 clutch, Injen CAI, 2.85 pulley and GMPP performance exhaust.

 

I got the 2.8 pulley and i think mine are gapped at .37 Works great

 

2.5-2.7=0.035
2.8-2.9=0.040
3.0-3.3=0.045

thats the rule I go by.

 

gaped them at .035... less chance of knock

 

Thanks Guys
