Fan Favorite Killer B Motorsport Coolant Breather Fitting Assembly – 2015-2021 Subaru WRX

Description

This is the Killer B Motorsport Coolant Breather Fitting Assembly. On the FA20 WRX engine, the OEM breather/coolant fitting is made using plastic materials that can degrade over time, and eventually create a leak. And because of the multiple heat cycles, the OEM unit can break when performing maintenance that required removing or replacing the lines during an AOS install. Killer B has designed a proper solution by designing an aluminum unit that will provide you with long-lasting, and leak-free reliability.
