More from AMS:
Even if your car is stock, you’ll find an oil film in your intake tract due to the inadequate factory PCV system. As boost increases so do oil vapors. If you are using ethanol based fuels and/or are using a rebuilt aftermarket engine the problem gets worse. Much worse. Usually the problem surfaces with oil coming out of your blow off valves making an oily, stinky mess in your engine bay.

Maintenance Free Oil Recovery
To solve the problem of excess oil vapor blow-by, our 3 tier design (air inlet, air outlet, reservoir base) effectively separates the oil discharging it back into your oil pan where it belongs. Often when installing a typical “oil catch can” the oil just sits in the reservoir until it is manually drained. By incorporating our oil drain back system (with check valve) you never have to worry about draining your oil catch can. This lessens your chance of running low on oil or the can overflowing into your engine bay.

Built To Last The Life Of Your GTR
The CNC billet aluminum body of the Alpha GTR Air/Oil Separator is black anodized for corrosion resistance and a stealthy look. We also use high quality seals and AN fittings. An Alpha logo is machined into the top as a nice finishing touch to your engine bay.
