Details:

Reduce Detonation, The octane level of oil is very low. Easy Disassembly For Cleaning, Over the years, a slight buildup may occur inside your AOS. This allows for better venting and reduces the chance of oil being ingested during high corners common issue on flat type or boxer engines. Incorporating a PCV reduces the smell from exhaust and keeps your intake tract clean.

By keeping the AOS same temperature as engine and blow-by gases, water condensation is decreased allowing oil vapor to separate pass through can. This means little maintenance or upkeep. Grease, tool marks. The PERRIN AOS is designed to connect each of these separately without requiring any connections.

This builds up over time which causes a loss in power and extra wear tear on your valves. HEATED BY COOLANT, The base plate of the AOS is heated by coolant drawn from engine. INCREASE INTERCOOLER EFFICIENCY, The AOS increases inter cooler efficiency by reducing the amount of oil deposited into your and intake system. For Left Hand Drive Vehicle only, The PERRIN Air Oil Separator traps oil from the crank case vents before it enters intake, increasing inter cooler efficiency, and reduces chances of Performance-robbing detonation.

This small feature is one of the many things that makes PERRIN AOS stand out from rest. This can be quickly taken care of by removing one bolt to access the inside for cleaning. Like the AOS body, drain fitting is threaded to except virtually any kind of allow for easy customization on special projects. Catch cans capture water and oil vapor filling with a sticky mess requiring it to be emptied.

Crank case blow-by is recirculated back to the intake be ingested by engine, but in doing so, gets stuck tract, valves, and inter cooler. As oil accumulates on all the walls, gravity pulls it to bottom of can where drains back engine block while water vapor and air merge with intake are re-burned in. This leads to power loss and detonation, which can be damaging your engine. The PERRIN AOS separates engine oil from water vapor and allows it to drain back into.

As blow-by/oil builds up inside your inter cooler, the less efficient it becomes due to heat being transferred away from engine. Does not work on vehicles with EyeSight. PCV System Included, We designed the PERRIN Air Oil Separator kit based on idea that using a AOS outlet ensures proper crank case venting during light loads and helps reduce unwanted blow-by gases into your intake system. SWIRL POT TECHNOLOGY, THIS IS NOT A CATCH CAN, The PERRIN Air Oil Separator is not a catch can.

REDUCE CARBON BUILDUP, Reduce carbon build up in the combustion chamber, intake valves, and your tract. Oil entering from the crankcase vents spins counter clockwise through entire body of AOS, passing along four walls equaling roughly 50.25 sq/in surface area. SUBARU SPECIFIC, Subaru engines have 3 main crank case vents located on each valve cover, and one in the center. Finish, Powder coated for protection against the elements, textured finish will look awesome years to come.

The multiple baffle walls in our compact design simulate the surface area of an AOS that is 13.5 tall. Anytime there is a significant amount of engine blow-by oil being put back into your engine, it reduces fuels octane level leading to detonation or knock, which will cause loss power and failure.
