CFM Performance 1'' Universal Billet Baffled Push In Valve Cover Breather Grommet (Without Check Ball) (Textured Black)

CFM Performance now makes it easy to vent the crankcase on your engine with our new billet valve cover baffled breather kit. This kit is universal for any valve cover with a 1.2" diameter port. New rubber grommet supplied with the breather.
Our push-in breathers are offered with two different options:


With check ball - Air is only allowed to exit the crankcase. It cannot enter the crankcase. This option is used with a PCV system that already has another source for air to enter the crankcase when under vacuum. Also used in applications with a mass airflow sensor so that unmetered air does not enter the crankcase.

Without check ball - Air is allowed to exit and enter the crankcase. This option is used when the PCV system needs a source for air to enter the crankcase when under vacuum. It can be used in applications where the PCV system has been deleted.

Our breather is the original on the market to incorporate a one-way check valve, keeping unmetered air from entering while the crankcase is under vacuum. In other words, this breather acts just like the factory oil cap, sealed under normal driving conditions. Only until positive pressure becomes present does the breather open to vent unwanted crankcase pressure.

This breather also has an integrated three-layered baffle and stainless steel mesh disc media to help contain oil particles that are carried by the crankcase pressure.

Our filter elements are washable and can be re-oiled similar to most aftermarket filters (i.e. K&N). Our large selection of high quality finished filter tops will be sure to add some style to your engine bay.

Although this breather was designed for use in racing applications, additional crankcase pressure ventilation is beneficial for any motor. Plus, our breather looks great in any engine bay!
