I would've went with the bpr6es or 7's with that set up.

well im going with larger injectors very soon and maf translator. After that im looking for a 18g or 20g. i guess ill save them and order the 7s

And get BR7ES, non-projected since the higher boost, which cause higher compression has a tendency to blow out the spark on projected plugs.

You get that spark on top of the combustion chamber, and the blowout possibility is drastically reduced.

That way, you can still use the .028 gap setting.

whats the difference between bpr7es and br7es?

Bpr7es are projected. Br7es are not. Get Br7es.

Bpr7es are projected. Br7es are not. Get Br7es. Most of the time, the auto parts stores wont have the br7es in stock. Order them.
