Fits select 2020-2026 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD models (6.6L).

Protect your heavy-duty engine from the performance-robbing effects of oil vapor with the J&L Oil Separator 3.0. During normal operation, crankcase pressure is vented back into your intake tract. This allows oil vapors to accumulate in the intake tube and manifold runners, which can dilute your fuel and effectively lower its octane rating. This multi-stage system intercepts those vapors, keeping your intake system clean and your combustion efficient.

The J&L 3.0 is precision-milled from solid billet aluminum and features a clear anodized finish. It utilizes a two-stage filtration process: first, a fine mesh stainless steel screen traps fine vapors, followed by a 1/2-inch thick, 1/16-inch aluminum honeycomb filter where droplets coalesce and fall into the 3 oz reservoir. The knurled tank base allows for easy tool-free removal during maintenance intervals, while the integrated O-ring seal ensures a leak-free system.
