We're a company that likes solving problems. As some of you FA20 WRX enthusiasts have found, the OEM plastic breather/coolant fitting can start to leak over time, or worse, break when you're trying to remove/replace lines during a build or AOS install.
So in typical Killer B fashion, we have designed a no fail, no leak part and put our own performance spin on it as well; opening up the breather port as the factory plastic piece is restrictive.
- No Fail, No Leak Replacement for OEM Fitting
- More Open Than the Restrictive OEM Design
