89-91 (88-91 JDM) Turbo II FC3S RX7 S5 Secondary Fuel rail (N371-13-150)In S5 FC Rx7 (Japan calls it Kouki) , Mazda (Denso) changed the way on how the pressure regulator mounts, so the S5 version it's all built in as a complete assembly (S4 is replaceable, but they leak easily) But on the other hand, if this goes bad you have to replace the whole assembly. This part has been NLA for a while, we've been asking them to re make them, and we finally got them! Part: N371 13 150

I wanted to replace the filters in my old G30 more frequently, as it's still running like a champ. I figured keeping up on it more often would help prolong its life expectancy. So far, so good. The less expensive replacement parts definitely help me not get upset every time I want to replace something. All parts from this pack fit perfectly, and the price is reasonable enough to avoid pushing replacements to the very last minute—at least it did for me, lol.
