Standard: AC MR43T or NGK BR6FS

Projected Nose: AC MR43TS or NGK BPR6FS

Gap = .035-.040"

I use NGK BPR6FS in my 502 MPI. The standard plugs work fine but
I get a little cleaner burn with the projected nose plugs.

NOT! looking to hijack, but, curious?

Same plugs would work in a 96 454EFI? calls for MR 43T's as "stock" as well. Also, whats the K&N number for the oil filter?

Thanks!

Same plugs. Don't know the K&N filter number. Just cross ref it with a Mobil1 M1-302.

NGK YR5 vpower v grove center electrode better idle and more resistant to fouling

Are they interchangeable?
