Direct injection engines can suffer from deposits on the backside of the intake valves. On older engines, these were washed off by the fuel spray - but not anymore. This is particularly a problem with boosted engines as they tend to have more oil vapor in the crankcase. The stock PCV system burns this off by feeding it into the intake air, which increases the buildup on the intake valves. To make matters worse, the usual gas additives that clean off your valves don't work because the fuel is injected directly into the cylinder, bypassing the valves.

We worked with Verus Engineering to test their newest air/oil separator. This device supplements the stock PCV setup. It collects the air from both the crankcase and the head. It's then run through a separate 5 micron coalescent filter for each source, then the air passes through a series of baffles and stainless mesh. All of these parts - including the filters - are intended to help the oil come out of suspension and separate from the air (hence the name). Since the filters don't hold anything back, they don't need to be cleaned or replaced. Two more 5 micron coalescent filters give the air one final scrub before it heads for the intake manifold and intake piping. The extracted oil is captured by the separator and can be easily drained with a turn of the drain valve. This allows you to monitor the level of oil vapor in the engine, which is an indicator of engine health. It also includes a forced-induction compatible PCV valve which can cope with positive intake manifold pressure.

We have tested this on track with one of our turbo NDs, and it works well. Naturally, it's made of 6061-T6 aluminum and anodized black for long life.

If your car is equipped with a sound tube, you will need a sound tube delete. Otherwise, everything you need is included.

Please note that this isn't legal for California since it doesn't drain back to the oil pan. We prefer to keep the gross things that your AOS pulls out from returning to your oil system, but if the AOS isn't drained and fills up, ugly things can happen and your emissions will increase. For this reason, we can't ship this to California (we know, but we don't make the laws). 

This is intended for LHD (left hand drive) cars. It will work on RHD cars, but be prepared for some problem solving - you may need to tweak the mounting and hose routing a bit. RHD customers tell us it's a solvable problem, but it's not something our instructions will address as we don't have any direct experience with RHD cars.
