Celica Forums General Discussion Exterior BPV

Where is the best place to cut the CAI for the BPV???

Pictures would be helpful too. Thanks.

Anyone???

BPVs don't work on our cars.

In turbo engine that uses VAM (Vane air meter), which people call them flapper-type AFM (air flow meter), BPV reroutes the air from (turbo-to-TB section) to (AFM-to-turbo section)
In speed density system or hotwire-type AFM, BPV is not need. You can just vent it out (BOV)

LOL, I thought he meant bypass valve.

The same thing I was trying to explain. Read my post

Hehe, nope, two different things. I was talking about the kind of bypass valve that keeps a CAI from sucking water into the engine if the filter is submerged, and you were talking about turbo systems.

I see.
You mean the AEM "Air bypass valve".

Yup.
