True. I ran them with flat top pistons. I prolly would not run them with dome top pistons.

The "P" stand for "projected center electrode insulator" The electrode stick out further on the BPRES plug vs BRES plug...So it might hit the top of your piston.....Just run the BR8ES plug and be done with it.
 
My 2006 SJ call for a B7HS. I've got a :):):):) load of BR8ES and BPR8ES and I was temped to just use them. The "HS" has a shorter thread. The "ES" has a longer thread that will be exposed inside the cylinder. It was suggested to me that a carbon build up on the exposed threads might not be a good thing when removing the plugs.

What do you guys think about that?

HS=stock head.. ES=aftermarket head
 
dam another kind, holy crap whats egv stand for

The EGV is a "Gold-palladium center electrode Special Construction of V-Type, for Racing use". The V type is a "Fine wire gold palladium center electrode".
It's a fancy more expensive plug. Can't hurt to use them, but not always a noticeable improvement, depending on how your motor is set up and what you are doing.

Half shaft is for stock heads. Extended shaft is for aftermarket heads. DO NOT. Put an extended shaft in if you have a stock head. The shaft will hit the piston on the way up and do serious damage.
