  1. Bob's Auto Sports Bare Bones Oil Separator
    $129.95

    Patent Pending

    Bare Bones Oil Separator

    Drilled for 3/8" NPT thread.  This is a bare bones kit so you can use your own fittings and hose to design the look you want! Keep HP robbing oil out of your intake with Bob's Auto Sports oil seperator. Developed to eliminate oil from entering your intake by engine blow-by, which channels oil contaminated air into your supercharger. A key problem caused by oil in the intake is that it reduces the octane of your fuel and causes detonation especially in turbo, supercharger and nitrous applications. Featuring a large chamber, and superior filtering media, this is the unit to have for road racers.  Draining the fluid is easy with a valve in the bottom.

  2. J&L Oil Separators Oil Separator 3.0 Passenger Side (2005-2010 Mustang) - 3013P-C
    $159.00

    J&L Oil Separators Oil Separator 3.0 Passenger Side (2005-2010 Mustang) - 3013P-C

    3oz Capacity
    Solid billet construction
    Quick connect PCV fittings
    The multistage filter is designed to collect the finest of oil vapors and drop them into the removable bottom while allowing clean air to pass through to the intake.

    During the process of venting crankcase pressure back through your intake track, large amounts of oil, in the form of vapors can gather/accumulate in your 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.

    Filtering consists of a fine mesh stainless steel screen that traps fine oil vapors and releases them once heavy enough to fall. They then pass through a 1/2" thick 1/16th" aluminum honeycomb filter where they grow every larger and then fall into the bottom. By the time the oil gets through the filter it's too heavy to be passed on into the intake. 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 2000-3000 miles and you will never come close to filling it.

  3. Steeda Oil Separator (1979-2020 Mustang / 2003-2004 Cobra) - 555-3710
    $99.95

    Steeda Oil Separator 79-04 Mustang - 555-3710

    Steeda's oil separator kit reduces detonation, oil burning and deposits on the valves by removing oil drawn through the PCV system before it can contaminate the intake charge. Originally designed for the '03-'04 Cobras, this kit features a clear bowl and is designed for a 3/8" and 1/2" PCV system. Mounting bracket included.

    Excess crankcase pressure (sometimes known as "blow-by") is vented from the crankcase through the PCV system, where it is drawn into the intake manifold and returned by the engine. This re circulated air contains aerated oil from the crankcase which is burned by the engine. Supercharged, nitrous-boosted and high mileage engines often draw excessive amounts of oil into the engine through the PCV system. The Steeda oil separator plugs into the PCV hose between the PCV valve and the intake manifold and removes aerated oil from the re circulated air and collects it in a tube that can be drained and recycled.

    Oil separator kits include the oil separator and required hardware. For 04-earlier applications connecting hose is included.

    Originally designed for the 03/04 Cobra's, this kit features a clear bowl and is designed for a 3/8" and now a 1/2" PCV system. Mounting bracket included.
