The J&L 3.0 oil separator (passenger side, black anodized) prevents oil vapors from re-entering the intake on modern 3.5L engines. Milled from billet aluminum with a knurled removable base, it uses a multistage stainless mesh and aluminum honeycomb filter to collect oil that drains into a 3 oz reservoir. Fits 2021–2026 Ford F-150 3.5L and 2022–2026 Ford Expedition 3.5L applications; drain every 2,000–3,000 miles.
