The J&L Oil Separator 3.0 (passenger side, black anodized) is specified for 2016–2021 Honda Civic 1.5L Turbo EX and Si models to prevent crankcase oil vapors from re-entering the intake. Solid billet construction with a multistage stainless mesh and aluminum honeycomb filter collects oil into a removable 3 oz tank. Knurled base and O-ring seal simplify servicing; drain every 2,000–3,000 miles to preserve intake and fuel quality.
