AMS Performance Air Oil Separator For Nissan GT-R

VENDOR: AMS Performance

SKU: ALP.07.04.0023-1

All orders will include an AutoTalent window decal



The Alpha Performance GT-R Air/Oil Separator is designed to remove oil vapor from your VR38’s crankcase before it ends up in your intake tubes and combustion chamber.  Oil vapor blow-by can have a detrimental effect on your engine reducing power output and even causing harmful detonation by altering your air/fuel ratio.

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.

The CNC billet aluminum body of the Alpha GT-R 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.
