anyone know what the whp gain would be with a aps cold air intake on a wrx?.. sti? mods... boost controller, u-p,d-p, exhaust fuel management, aps fmic, vf34, perrin pulley.. i think that's it
I helped a friend try to tune his car recently with an APS intake. We couldn't get it to run. Tried it on my car, it ran horribly as well. Stay away from it.
Well, some of us have to run an aftermarket intake...
I have the Perrin on my car, and it runs fine. No lean problems like many other models. It doesn't have the curve just before the MAF sensor like a lot of other designs. Doesn't effect my AFR like the others.
Jeez Cosmo, how often do you change your intake. You have one old pic of the Perrin on, one new pic w/ the AEM one on, now back to the Perrin? What gives?
