- Description
Our Exoracing block breather fittings are specially designed for Honda B-Series engines and are an excellent replacement for the OEM breather box port. They allow for a hassle-free connection of 10AN hose ends, providing a highly efficient catch can or breather system.
The OEM breather box typically recirculates excess crankcase gases into the intake system. However, venting these gases into the atmosphere can increase power output. This method ensures that only pure air enters the engine, resulting in a slight but noticeable boost in performance.
These versatile fittings can also be used in B-Series cylinder heads to facilitate dry-deck cooling system setups. This feature is handy in racing applications where coolant only runs through the cylinder head. With our Exoracing block breather fittings, you can be confident that your Honda B-Series engine is equipped to deliver optimal performance.
