THERE WILL BE NO RETURN ALLOWED FOR THIS ITEM. PERRIN PERFORMANCE - AIR OIL SEPARATOR. The PERRIN Performance Air Oil Separator traps oil from the crank case vents before it enters the intake, thus increasing intercooler efficiency and reduces chances of performance-robbing detonation. Featuring swirl pot type technology and multi-layer baffles, the PERRIN Performance Air Oil Separator forces incoming air to circulate across the baffles, separating oil from engine blowby.

The AOS increases intercooler efficiency by reducing the amount of oil deposited into your intercooler and intake system! As blow-by/oil builds up inside your intercooler, the less efficient it becomes due to less heat being transferred away from your engine. This leads to power loss and detonation, which can be damaging to your engine. Reduce carbon build up in the combustion chamber, intake valves, and in your intake tract. Crank case blow-by is recirculated back to the intake to be ingested by the engine, but in doing so, gets stuck in the intake tract, intake valves, and the intercooler.

This builds up over time which causes a loss in power and extra wear and tear on your valve train. The octane level of oil is very low. Anytime there is a significant amount of engine blow-by (oil) being put back into your engine, it reduces your fuel's octane level leading to detonation or knock, which will cause loss of power and engine failure. We designed the PERRIN Air Oil Separator kit based on the idea that using a PCV on the AOS outlet ensures proper crank case venting during light loads and helps reduce unwanted blow-by gases into your intake system. Incorporating a PCV reduces the smell from exhaust and keeps your intake tract clean. Over the years, a slight buildup may occur inside your AOS. This can be quickly taken care of by removing one bolt to access the inside for cleaning. This small feature is one of the many things that makes the PERRIN AOS stand out from the rest. This is not a catch can! The PERRIN Air Oil Separator is not a catch can. Catch cans capture and water and oil vapor filling with a sticky oily mess requiring it to be emptied. The PERRIN AOS separates engine oil from water vapor and allows it to drain back into the engine. Oil entering from the crankcase vents spins counter clockwise through the entire body of the AOS, passing along four walls equaling roughly 50.25 sq/in of surface area. The multiple baffle walls in our compact design simulate the surface area of an AOS that is 13.5 tall! As oil accumulates on all the walls, gravity pulls it to the bottom of the can where it drains back to the engine block while water vapor and air merge with the intake air and are reburied in the engine. This means no maintenance or upkeep. The base plate of the the AOS is heated by coolant drawn from the engine. By keeping the AOS the same temperature as the engine and blow-by gases, water condensation is decreased allowing oil and water vapor to separate and pass through the can. This vital feature eliminates nearly all the sludge that can build up in the AOS body, which drastically reduce how often you must clean it.

Instead of using a universal type fitting, we have designed a purpose built crank case fitting that does the job perfectly. Like the AOS body, the drain fitting is threaded to except virtually any kind of fitting to allow for easy customization on special projects. Each kit comes with specific mounting brackets and instructions to install your AOS perfectly in your engine bay or adapt our simple 2 hole mounting bracket for custom installations. Every connection on the PERRIN AOS is threaded NPT which is a very universal way to connect fittings. This allows for totally customizable setups and installations to be done, to best match your setup.
