Moroso Air Oil Separator Subaru WRX 2006-2007 / STI 2004-2007

Part: # 85484. Factory - installed vehicles often vent excess crankcase vapors, residual oil, and moisture back into the intake manifold and crankcase ventilation system. This can coat pistons and other components with an oil layer prone to detonation, which is a big no - no for turbocharged cars. Moroso's innovative 2 - tank system allows the factory crankcase ventilation to work as intended, a feature unmatched by other systems on the market. The billet aluminum bodies not only add a stylish touch to any engine compartment but can also be polished, chromed, or powder - coated for a personalized look. Each separator comes with a billet aluminum clamp and a bottom drain with an elbow for mess - free oil drainage. The kit includes stainless steel mounting brackets, 1/2' inlet and outlet fittings, 66' of 3/8' diameter and 66' of 1/2' diameter rubber hoses for inline plumbing. Note that this kit is designed for cars with a TMIC and stock location turbo and is not suitable for FMIC or rotated mount turbo setups.

Using this Moroso Air Oil Separator is quite straightforward. First, use the included stainless steel mounting brackets to securely install the separator in your engine compartment. Connect the 1/2' inlet and outlet fittings with the provided rubber hoses to integrate the separator into your car's ventilation system. Make sure to follow the proper plumbing diagram to ensure everything is connected correctly. When it comes to maintenance, regularly check the collected oil in the separator. You can easily drain the oil through the bottom drain with an elbow, which is designed to keep the process clean. Keep in mind that this kit is only for cars with a TMIC and stock location turbo. Don't try to use it with a FMIC or rotated mount turbo as it may not work properly and could potentially damage your engine.
