JH Motorsports is proud to introduce our new Billet Crankcase Breather Vent Hose Kit - PCV for the B8 RS4 and RS5!

Factory PCV units often fail allow too much engine vacuum into the crankcase. This typically causes loud whistling noises as air is being sucked around engine seals such as the rear main. The OEM PCV unit is very costly, averaging over $700 for the pair. Our solution to this problem is a Billet unit that is not only more cost effective, but is more robust than the factory units and serviceable!

Features:

Precision CNC'd Billet Aluminum
Black Anodizing
Stainless Braided Lines
Easy/Simple Installation
Serviceable
MADE IN THE USA!

Additionally, this PCV unit is a prerequisite for the JHM RS5 Supercharger Kit!
