CFM Performance valve cover breathers are the best money can buy and is the reason they have become extremely popular so quickly. They are so much more than a pretty filter on top of your valve cover and offer features that no other kits offer.

It is the only breather on the market which incorporates a check ball to keep unmetered air from coming through while the PCV system is active and the crankcase is under vacuum. In other words, this breather works just like a factory oil cap under normal driving conditions but will vent any positive crankcase pressure present under full or part throttle. It is also the only breather with an integrated baffle to help contain oil particles in the engine rather than allowing them to exit the valve cover and saturate the filter element. Filter tops are available in several popular powdercoat finishes, chrome, hydrocarbon and select OEM colors.

CFM Breather Features:

  • Relieves positive crankcase pressure
  • Direct replacement for oil cap
  • One-way check ball for MAF based cars
  • Internal baffle separates oil/air
  • Retains factory PCV system
  • Made from 6061 aluminum
  • Cleanable breather filter
  • Numerous finish options
