How Does It Work?

During the process of venting crankcase pressure back through your intake track, large amounts of oil vapor can gather in your intake tube, intake manifold runners, and even dilute your gas, lowering its octane level. This occurs in all engines and is even more pronounced in forced-induction vehicles (supercharged and turbocharged) due to increased crankcase pressures.

To combat this, we developed our own oil separator, precision-milled from solid billet aluminum. This durable component features a knurled tank base for easy removal to drain the collected oil and an O-ring seal to prevent leaks.

Advanced Filtration System

The filtering system consists of a fine mesh stainless steel screen that traps fine oil vapors. As the vapors accumulate, they pass through a 1/2" thick 1/16" aluminum honeycomb filter, where they condense further and fall into the reservoir. By the time the oil reaches the bottom, it is too heavy to be passed into the intake, effectively preventing buildup and engine damage.

The tank holds 3 oz of fluid. While that may not seem like much, excessive oil in your PCV system is uncommon. Simply drain it every 2000-3000 miles, and you'll keep your engine running clean without ever coming close to overfilling.
