Why use An Exoracing Crankcase Breather Filter?

Exoracing crankcase breather filters increase your car's performance and reduce crankcase pressure. These compact filters are a popular aftermarket solution, replacing recirculating pipes.

They attach to the OEM vent port on the engine's rocker cover, preventing foreign objects from entering the line and allowing airflow through the crankcase, eliminating gases that would otherwise return to the intake, a by-product of the combustion cycle.

This, in turn, keeps the intake air cleaner and denser with oxygen, allowing for a slight horsepower bump.

Our filters are available in various colours, and some of the housing is anodised to match the theme of your engine bay. Additionally, we include a jubilee clip that fits perfectly, making installation quick and effortless.

The Exoracing crankcase breather filters are multipurpose and can be used in cars and motorcycles due to the 12mm neck shared over many vehicles.

Crankcase Breather filters are an excellent solution for enhancing their vehicle's performance. By eliminating crankcase pressure, these filters can help your engine perform more efficiently and, ultimately, last longer.

So, if you're looking for a reliable, high-quality filter to help you get the most out of your engine, look no further than our Crankcase Breather filters.

We now offer an Exoracing lifetime warranty on all of our filters, so enjoy a peace of mind knowing your purchase is risk-free!

Exoracing Crankcase Breather Filter Installation Guide:

Installation of our breather filters is quick and easy; follow the steps below.

  1. First, remove the old breather line from the 12mm crankcase outlet.
  2. Ensure the worm drive clip is installed on the rubber section of the breather filter, and press fit the filter over the 12mm tube.
  3. Tighten the worm drive clip using a socket or Phillips head screwdriver until secure.
  4. Do not knock or pull on the filter head, as this could cause the rubber to dislodge from the filter housing.
  5. You are all done! Remember to tag us in any photos on social media, as we would love to see them!
