The J&L oil separator for the 2022–2026 Hyundai Elantra N 2.0L (passenger side) is a billet-aluminum crankcase vent collector that traps oil vapors before they reach the intake. It uses a multistage stainless mesh and a honeycomb filter to separate fine vapors, holds about 3 oz, and has a knurled removable base with an O-ring seal. Drain every 2,000–3,000 miles to maintain effectiveness.
