928 Specialists SharkVent Crankcase Ventilation System for 85-86 32V 928

Technology developed for our SharkCharger Twin Screw Supercharger Kits now available for all 928s.

The stock 928 breather system routes crankcase oil vapors through the intake so that it is burned in the combustion chambers.
Our New SharkVent System completely eliminates any oil vapors going back into the intake.

Some of the benefits of preventing the oil from entering the intake of your 928 are:

 Reduced oil consumption.
More power and better fuel economy.
Reduced tendency to knock or ping.
Cleaner intake tract, ports, valves, and combustion chambers.

 The complete SharkVent kit, based around the proven Mann-Hummel ProVent Air/Oil Separator, features: 

Bolt-on, simple installation,
Self contained, no messy catch can to worry about.
Separated oil drained to oil pan via custom oil Pan Adapter.
Integrated check valve in oil return eliminates crankcase back pressure through the SharkVent.
Adapters to cap or plug original vent ports.
Separated Clean Air exits into a Breather Filter.
Optional Hose available for connection to the factory air pump:
 (increases crankcase vacuum, evacuates separated air through exhaust system)
