which are NGK racing plugs? I know NGK come stock with our cars, and i use them. Not platinum ones because they cost more and I change them so often so why do it.

I use to run B9EGV all the time. Have now changed over to BR9EIX.

A friend who use to run the $20+ pure race plugs now runs BR10EIX and says not only are they much cheaper but run just as well even at 19PSI boost with water injection.

What mods do you have/horsepower? Unless you are pretty heavily modded, the stock trailing plugs all around work great. I don't think the 10.5 plugs would run very well in street driving, but I could be wrong.

I have pretty much the same mods as you and run NGK 10.5's all the way around. No problems at all with street driving. They are expensive, but the plugs don't need to be change *that* often. Just take them out every once in awhile and clean them off.

Is your car tuned at 15psi??? If its not you dont need to be running that boost level. Only run what your car has been tuned for.

To answer your question about plugs, IF it was tuned at 15psi I'd run the same plugs that were in it when it was tuned

If you do want to try something else, go wtih the plugs Chuck (cewrx7r1 ) mentioned. I also run those plugs with heat range 10 and a gap of .022 They work very well. Your going to need a special plug socket for them though, there is a guy that sells them on the forum for like $20 shipped. I think its metalman or something. Do a search in the forsale section for socket and I'm sure you'll find it. If not PM me.
