The Killer B Motorsport High Performance Oil Control Valve keeps oil from flowing out of the head breather ports while under high cornering loads. When oil is allowed to flow out of the head ports, oil level in the sump can drop, causing starvation.
This part is recommended for TRACK cars only. It is neither recommended nor useful for street cars, or even for cars doing HPDE track sessions on street tires. We recommend this part for track use with dedicated track tires where sustained cornering loads will exceed 1.0G.
This part will be normally be installed in conjunction with an air/oil separator system, which is sold separately. The Oil Control Valve bolts to the firewall; a bracket is included, but depending on your hardware setup be prepared to adapt or create your own bracket.
One Oil Control Valve is required per car.
Fits all 2008-2014 Subaru WRX and 2008-2021 WRX STI.
