Product Description
Killer B 2015+ Subaru WRX Coolant Breather Fitting Assembly
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 an AOS install.
So, in typical Killer B fashion, we have designed a no fail, no leak part. We've put our own performance spin on it as well, opening up the breather port, as the factory plastic piece is too restrictive.
No Fail, No Leak Replacement for OEM Fitting
More Open Than the Restrictive OEM Design

Nice If You Install Correctly

I wrapped the fitting wrong and it leaked. After I fixed that it has worked well.

I saw this part a while back and thought who would need that. Low and behold I busted mine off while I was installing my AOS. I didn't realize how brittle the plastic gets after a couple years. This is a much stronger piece. I plan on switching to AN fittings later on so its nice that these fittings can be removed.
