Apex Seals

[classicauto]

Yes, you absolutely DO NOT want carbon seals. They are for N/A *only*

Personally, not a big fan of atkins apex seals. Had a strange failure with a set, which may or may not have been the seals themselves, and just lost trust right off the bat.

I've run OEM 2mm, 2piece for everything after that, and Iv'e had failures, but they didn't have ANYTHING to do with the seals themselves. The set in my car right now puts down 380whp. ALL OEM.

IIRC, mazda apex seals are about $30 each.

No experience with RA.

Know some guys running ALS, if you want a cheap set of "race" seals get them, they're pretty good. As for benefits over non-race seals, good question.
