How It Works
Under normal operation, crankcase pressure vents back into the intake track, carrying oil vapors that can coat intake runners, dilute fuel, and reduce octane levels. The J&L Oil Separator 3.0 captures these vapors before they reach the intake system. A fine stainless-steel mesh screen traps oil mist, while a 1/2-inch thick aluminum honeycomb filter allows droplets to condense and collect in the bottom reservoir. The result is cleaner air entering your engine, better combustion efficiency, and less carbon buildup.
