The Killer B Motorsport FA20 WRX Air/Oil Separator - this is a product we’ve been asked to develop for many years, and in that time there has been a lot of research, engineering, simulations, development, testing, (and repeat), with several different Subaru engines and build types, including stock engines.
The goal of this product is simple. To function as its Air/Oil Separator name implies: to remove oil, in liquid or vapor form, from the vented crankcase gasses. Simple in premise, but functionally there’s a bit more to it. Oil droplet sizes vary with differing pressure and velocity conditions. Different engines vary in their venting characteristics. Street cars vary from track or performance elevated engines. The list of variables goes on, making acceptable function and performance a difficult challenge.
Filtration is a proven process for separation of many particle types and sizes. The application in automotive applications has mostly been in use with high dollar sports cars and racecars.
- Collected oil drains back into the crankcase where it belongs.
- Applies vacuum to the crankcase improving ring seal, reducing oil consumption and improving power potential.
- No media to clean/replaces or baffles to inhibit crankcase flow
- Made of billet and TIG welded 6061-T6 Aluminum
- Killer B Motorsport push-lock barb fittings require no hose clamps
