High-performance air/oil separator designed for race and track applications. Features a 0.1L short or 0.5L medium CCR (Closed Crankcase Recirculation) closed system option for optimal crankcase pressure management and oil vapor control.

Our approach to crankcase pressure and management is to assist you with the best products we have tested on the racetrack. We currently are not offering the hose kit for this system, but will manufacture them on cars we build in-house and in the near future have these available for purchase. Due to the nature of making the crankcase system closed, with automatic drain-back to the engine’s crankcase, the OEM system must be disabled and/or removed. To do this fully, you can leave the OEM plastic tank attached to the back of the water pump, or remove it by draining the cooling system, ordering the correct FelPro gasket kits and replace the lost coolant.

To implement this upgrade, you must cut the original drainback hose, using a Push-Lock -10an fitting and secure it with clamps. If we can find a reasonable amount of these fittings, we will possibly offer this as part of our kit, or sell the item premade with a core charge. If you are using the stock aluminum supercharger crossover tube and not our full reverse flow hose kit, choose the 0.1L Short version for a better fit.
