AIS blockoff and a PCV.
When I can afford it I'll throw on an Akrapovic 4 into 1 system only so I can get to the chain for maintenance and shed a few pounds in the process.
.
Forgive me. I think I know what the AIS is (Air Intake System?), but what is a PCV? Where did you find these products?
EDIT: Power Commander! I so smart.
