Fits select 2019-2026 Cadillac Escalade/ESV, Chevrolet Silverado 1500, Suburban, Tahoe, and GMC Sierra 1500, Yukon/XL (5.3L).

Protect your engine's efficiency by preventing oil vapor from contaminating your intake tract. During normal operation, crankcase pressure is vented back into the intake; however, this air often carries oil mist that accumulates in the intake manifold, runners, and valves. This J&L Oil Separator 3.0 intercepts these vapors before they can dilute your fuel's octane or cause carbon buildup.

Engineered for professional-grade performance, this separator is milled from solid billet aluminum and features a multi-stage filtration system. Vapors first pass through a fine stainless steel mesh screen to trap heavy oil droplets, followed by a 1/2-inch thick, 1/16-inch aluminum honeycomb filter to capture the finest remaining particles. The collected oil drops into a 3-ounce reservoir that features a knurled base for easy removal and an O-ring seal for leak-free operation.
