Our Exoracing block breather fittings are designed to cater to Honda B-Series engines. They are an ideal replacement for the OEM breather box port, providing a convenient way to connect 10AN hose ends for a highly efficient catch can or breather system.
The OEM breather box typically recirculates surplus crankcase gases into the intake system. However, by venting these gases into the atmosphere instead, you can experience increased power. Notably, this method guarantees that only the purest air enters your engine, resulting in a slight yet noticeable boost in power output.
These fittings are highly versatile and can be utilised in B-Series cylinder heads to facilitate dry-deck cooling system setups. This feature is especially useful in racing applications where coolant only runs through the cylinder head. With our Exoracing block breather fittings, you can rest assured that your Honda B-Series engine is well-equipped to deliver optimal performance.
