Product Details
CFM Performance Baffled Billet Valve Cover Breather

CFM Performance now makes it easy to vent the crankcase on your 2011-2017 Mustang GT & 2012-2013 Boss 302 with our new billet valve cover baffled breather kit. This kit is a direct replacement for your factory oil fill cap and allows unwanted crankcase pressure to exit. 

This breather is the ONLY one in the market which incorporates a check ball to keep unmetered air from coming through while the crankcase is under vacuum. In other words, this breather acts just like a factory oil cap under normal driving conditions and when you get into boost it will release any crankcase pressure present.

The proprietary internal baffle substantially reduces oil particle travel without affecting air flow. The filter element is washable and has a variety of top finishes for great looks. The pre-oiled cotton fiber traps dirt particles without restricting air flow. Although this kit was designed for use in racing applications, it works and looks great in any engine compartment.



JLT Oil Separator (Passenger Side)

This kit is specific for the 2011-13 Mustang GT / BOSS 302 passenger side.

Includes factory PCV hose for easy plug and play installation

WILL NOT FIT WITH MOST SUPERCHARGERS, Fits with Magnacharger Supercharger (check out the BASE KIT and you can build your own)

Most of the oil will come from the passenger side, so if only getting one, this is the one to get!

JLT Performances newest product to keep oil out of your intake is the Oil Separator. During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, can coat your blower rotors, intercooler fins and even dilute your gas, lowering its octane level. This happens on all engines and is even worse when supercharged as crankcase pressures are increased.

To combat this, we have developed an oil separator of our own design. Milled from solid billet aluminum this is a rock solid piece. It has a knurled tank base for easy removal to drain the spent oil and an O ring seal to prevent any leaks. We took this unit a step further and added a Ford Motorcraft metal mesh PCV Pre Filter element. This element collects the last bit of oil droplets and drains back into the tank when the engine is shut down. We use this exact filter in our hugely successful JLT Pre Filters for the 4.6 DOHC engines. The tank holds 2 oz of fluid, while that may not sound like a lot, you shouldnt see that much oil in your PCV system. Drain it every oil change and you will never come close to filling it.
