ALL NEW J&L 3.0 Oil Separator

The new design is the 3.0 because it hold 3oz of fluid where the original held a little over 1oz. Solid and thick Billet construction Easy install with full directions and videos

This kit is specific for the 1999-2004 Cobra, 2003-04 MACH I driver side.

Includes instructions, fittings, hose and all needed hardware for an easy plug and play installation.

During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors, intake tube, intake manifold runners and even dilute your gas, lowering its octane level. This happens on all engines and is even worse with forced inducted vehicles (supercharged and turbocharged) 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 metal mesh filter to the intake side that collects the vapors, allowing them to grow into larger oil droplets and drains back into the tank. The tank holds 3 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 3500-4000 miles and you will never come close to filling it.
