BCPR7ES-11 vs. ZFR7F-11
What are the differences? Which plug is better?
This will be going in a B20B, 8.8cr, Ef-1 cams, stock ignition, 7-9psi on 60a/r 60trim T3 compressor.
Also, what gapping?
Any help is appreciated!

i jsut look that up in the helms book and it said that the b20 uses zfr5f-11 and the zfr7f-11 is two step coler so i think that would be better. for turbo.

i think the difference between those two are in construction. i see more boosted cars here usin the B's as opposed to the Z's tho. both would be two steps colder than stock.

i run bcpr's and for some reason i could never find htem but now i get them through a friend so they are easy to get, but i think the zf's are just easier to get a hold of
