Protect your engine from power-robbing oil vapor with the J&L Oil Separator 3.0. During normal operation, crankcase pressure is vented back into your intake track, carrying oil vapors that coat intake runners and dilute your fuel's octane. This billet aluminum separator intercepts those vapors, preventing carbon buildup and maintaining consistent combustion quality—a critical upgrade for both naturally aspirated and forced induction setups.

The J&L 3.0 features a sophisticated multi-stage filtration system. Vapors first pass through a fine stainless steel mesh screen before hitting a 1/2-inch thick, 1/16-inch aluminum honeycomb filter. This process forces oil droplets to coalesce and fall into the 3oz reservoir. Maintenance is straightforward thanks to the knurled tank base, which allows for easy removal and draining every 2,000 to 3,000 miles.
