Cobb Tuning Nissan GT-R Stage 1 to Stage 1 CAN Flex Fuel Fuel Pressure Power Package Upgrade 2009-2018 - LHD

The COBB Air/Oil Separator (AOS) prevents oil vapors from recirculating into the engine's intake system by being placed within the Ford RS's crankcase ventilation system. This results in cleaner valves and reduced detonation risk by removing oil particles from PCV gasses. It uses a drain-back system to return condensed oil to the crankcase. The AOS integrates a factory breather plate with a 33% glass-filled nylon spacer plate for perfect fitment. The COBB oil drain plate fits between the OEM air oil separator and engine block, utilizing an additional COBB-provided OEM gasket for a leak-free seal. Note: This AOS does not fit with the Ford Block Heater accessory kit installed.
