The J&L oil separator for 2021–2021.5 Ford Bronco 2.3L EcoBoost (passenger side, clear anodized) traps oil vapors using a multistage stainless mesh and aluminum honeycomb filter, returning captured fluid to a removable 3 oz reservoir. Machined from solid billet with quick-connect PCV fittings and an O-ring seal, it’s serviceable via the knurled base and should be drained about every 2,000–3,000 miles.
