looks like BPR7ES will be good for me..BTW...My dealer can check BPR7ES and BPR7ES-11..what is the differenece between????

The difference between BPR7ES and BPR7ES-11 is the gap. The BPR7ES-11 is a widegap plug and will not work properly because you cannot close the gap enough without affecting the spark. You want the BPR7ES.

That time and power is very possible. I pulled it off w/ a 16G. If you do it correctly, IMO, you should be hittin mid to high 11s w/ your mods. Yes, BPR8ES is a colder plug. Our EVO runs BPR9ES. It's boost is set @40psi though. Good luck.

..with 16G..good job tell me how ..my 50trim flow 49lb/min..your 16G around 40??don´t know sure..my setup miss cams,intake and some 9:1pistons.. but tell me someone can get BIG power from smaller turbo then someone else with BIG charger..Iam checking 1/4mile times(to get ideas what need to beat 12sec...) someone got tons of mods and is in 13sec..??
40PSIof boost.. damn..which gauge you are using

You think Iam able 11,5 to 12sec...

I run NGK B7es plugs in my car gapped to .028, non extended tip and no resistor, good results.

Okay...Go for 7ES...but tell me when you buy BPR7ES is already gaped to 0,028" or I have to gap it???This is what I need to know....Last question...

Mine were gapped to .030 when I got them. That's ok for lower boost, but for you, bring it down to .028 definitely. Make sure you use the correct tool to gap, not one of those coin shaped ones, but one that has a bunch of metal strips, and they fold out, like an army knife. Those are much more accurate.

You have to gap it yourself.

for those who care, they're called "Feeler Gauges"...
