The J&L 3.0 driver‑side oil separator for 2020–2026 Chevy Silverado and GMC Sierra 2500/3500 (6.6L gas) traps crankcase oil vapors before they reach the intake. Milled from solid billet aluminum with a knurled removable base, O‑ring seal, and multistage stainless steel mesh and honeycomb filter, it holds about 3 oz and should be drained every 2,000–3,000 miles to protect intake and fuel quality.
