The J&L 3.0 oil separator in black anodized finish is a billet aluminum PCV catch can made for 2005–2019 Nissan Frontier 4.0L and select 2005–2012 Pathfinder 4.0L applications. Its multistage stainless mesh and honeycomb filtration collect oil vapors while allowing clean air to return to the intake; the removable knurled base holds about 3 oz and should be drained every 2,000–3,000 miles for proper maintenance.
