Stock BOVs
does anyone know if the stock 3rd gen BOVs are the same as the 2nd gens?
it says JF01 on my FCs and N390 on a third gens... are there two different types of BOV on 3rd gens?
randomest question ever...

Mazda call it an "air bypass valve" but it's exactly the same thing.Jack, the only reason to swap in a FD BOV would be if it was bigger. Compare the connections and see. The FD one takes a little less vacuum to fully open it (9.2inHg vs. the FC's 11.8in Hg), but that shouldn't make any difference.
