The Racer X Fabrication catch can for the 2022+ Subaru BRZ / Toyota GR86 was designed to reduce oil in the air stream when exiting the PCV. The catch can / air oil separator works by intercepting the air oil mixture from the PCV, and through a series of baffles, retains the oil in the catch can and allows the air to flow through. As the air and oil droplets enter the catch can they are diverted around the spring/inlet tube. This initial diversion creates a swirling effect that is continued through the filtration process. Each baffle utilizes an offset hole pattern which can be rotated or flipped to promote an increased swirling effect which can be seen in the CFD analysis below. We specifically designed the baffles and perforation plate to assist in allowing the air to flow freely and provide the oil every opportunity to stay in the catch can. Once through the internal baffle system, the air will pass through the final perforation disc before exiting back into the vehicle system. The system has been tested and proven effective after multiple iterations of CFD analysis and road testing.

We include a stainless steel mini ball valve that allows for fast and easy draining. You will just need to place a canister below the catch can and open the ball valve to drain the contents. Knowing when to drain your catch can is simple, the Racer X Fabrication catch can has an easy view sight glass, so no more guessing.
