AMS PERFORMANCE R35 GT-R AIR/OIL SEPARATOR

The Alpha Performance GT-R Air/Oil Separator eliminates oil vapor from your VR38's crankcase, preventing it from entering intake tubes and combustion chambers. Prevents power loss and harmful detonation by maintaining proper air/fuel ratio. 

Remove The Oil Vapor Blow-by, Increase The Power! 

Even in stock cars, an oil film accumulates in the intake tract due to the factory PCV system's inadequacy. With higher boost, oil vapors increase. If using ethanol fuels or a rebuilt aftermarket engine, the issue exacerbates. Often, oil seeps from blow-off valves, creating a messy, odorous engine bay.

Maintenance Free Oil Recovery 

To address excess oil vapor blow-by, our 3-tier design efficiently separates oil and directs it back to the oil pan. Unlike typical catch cans where oil accumulates until manual draining, our system includes an oil drain back with a check valve, ensuring worry-free maintenance. Reduce the risk of low oil levels or can overflow in your engine bay.

Built To Last The Life Of Your GT-R 

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. 

Simple Installation 

Because we use all the existing OEM ports, plumbing is made simple.  We include all the brackets, lines and hardware for a turn-key solution.
