Product Description

JLT Performance’s newest product to keep oil out of your intake is the 2011-2014 Mustang 5.0L 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. This part number is designed to be mounted on the driver's side of the engine compartment.

To combat this, JLT has developed an oil separator of their 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. JLT 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. JLT uses this exact filter in their 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 shouldn’t see that much oil in your PCV system. Drain it every oil change and you will never come close to filling it.

This part number is designed to be mounted on the driver's side of the engine compartment.
