The J&L Oil Separator 3.0 passenger-side unit for 2016–2021 Honda Civic 1.5L Turbo (EX & Si) captures oil vapors before they reach the intake, helping prevent contamination and octane dilution in forced‑induction engines. Built from solid billet aluminum with an O‑ring seal and knurled removable base, it uses a fine mesh screen and an aluminum honeycomb to drop oil into a 3 oz tank. Drain every 2,000–3,000 miles.
