J&L Oil Separator 3.0 Driver Side Clear Anodized for Select 2019-2026 GM Trucks and SUVs (5.3L)

Protect your engine's intake tract and maintain fuel octane levels with the J&L Oil Separator 3.0. During normal operation, crankcase pressure is vented back through the intake, carrying oil vapors that coat intake manifold runners and dilute fuel. This driver-side separator intercepts those vapors, preventing carbon buildup and performance loss. Milled from solid billet aluminum, this unit features a 3oz capacity tank with a knurled base for easy removal during service.

The multi-stage filtration system utilizes a fine mesh stainless steel screen to trap initial vapors, followed by a 1/2-inch thick, 1/16-inch aluminum honeycomb filter. This design forces oil droplets to coalesce and drop into the reservoir while allowing clean air to pass through to the intake. Installation is straightforward using the included factory-style quick-connect PCV fittings.
