Why Use Exoracing B-Series Block Breather Fittings?

Our Exoracing B-Series 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 AN10 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, where coolant only runs through the head. This feature is handy in racing applications where coolant only runs through the cylinder head.

This kit is machined from 6061 billet aluminium, weighs only 143g, and is strong, making it the perfect product for a long-lasting breather system.

The M28 to AN10 fittings are machined to easily add AN10 fittings into the system, the market's most popular and universal system for fluid and vapour transfer. Most catch cans are now designed with AN10 fittings, making this the perfect pairing for your B-Series.

The block creates high crankcase pressure, especially in turbocharged systems, so the block plug includes a double O-ring design to ensure no oil vapour leaks past the fitting.

With our Exoracing B-Series block breather fittings, you can be confident that your Honda B-Series engine is equipped to deliver optimal performance and can breathe as efficiently as possible.

Exoracing B-Series Block Breather Fitting Installation Guide:

Please follow the guide below to install your new Exoracing B-Series block breather fittings correctly. If you are stuck or are not confident to do this yourself, please get in touch with a mechanic who can help you install our kit.

  1. First, you will want to stay by removing the entire OEM PCV system. This includes the pressed breather block fitted to the back of the block and all hoses connected to it.
  2. Next, using an Allen key or Allen-headed socket, remove the 2 OEM plugs in the block that are on either side of the hole that is now in the block.
  3. Ensure the two O-rings are seated correctly on the block plug, and install it into the centre hole, making sure not to pinch the O-rings as this may cause blowby. The best method is to install it lightly using a rubber mallet, pushing the fitting in as straight as possible until it sits against the machined lip on the fitting.
  4. Now, you will want to take an M28 to AN10 fitting, install an aluminium washer onto the M28 block side of the fitting, and thread it into one of the threaded holes. Use an AN10 or adjustable AN spanner to ensure no damage to the fitting whilst installing. Make sure the fitting is tight, and repeat this step with the second fitting.
  5. After installing the B-Series block breather kit, you can start plumbing your AN10 lines to a catch can, and then you're all done. Please tag us in any photos of the B-Series block breather installed, as we'd love to see them!
