The J&L oil separator for 2021–2021.5 Ford Bronco 2.3L EcoBoost (passenger side) is a billet-aluminum, multistage trap that collects oil vapors before they reach the intake. Its knurled removable base and O-ring seal allow draining of the three-ounce tank; the stainless mesh and aluminum honeycomb filter promote coalescing so oil drains back into the sump. Drain every 2,000–3,000 miles per manufacturer guidance.
