I had a Nitrous Guy tell me about these NON-projected tip plugs that he said I should be using/? He said a standard plug has a projected tip and that Nitrous, Blowers and Turbo's should use NON projected tip plugs to help prevent detonation? Any of you hear of this B4? What’s the deal with this type of plug? Just looking for some info because every time plugs have come up all I have seen guys use was TR6's - Which has a projected tip? What do you guys think?

i was reading an article in one of the muscle car magazines today where they did a dyno test with NGKs and the http://www.briskusa.com/products.htm plugs......the brisk gained a few hp and tq, and the nice thing is that you dont have to gap them.

the ones I like to use are.....NGK 5271-8 ( i believe that is the one with the gasket on them)
Just change the last number to 9 or 10 if you want them alot colder.
I use the gasket seat kind simply because it pulls the plug even further out of the head. I run a tight gap to bring some heat back in them and I do not care for idle qualities..AS long as the care starts idles in gear when i need it too then im good. These plugs are not for everyone, but they are highly recommended in the serious race applications.
