The J&L 3.0 oil separator in clear anodized finish is a billet aluminum PCV catch can for 2005–2019 Nissan Frontier 4.0L and certain 2005–2012 Pathfinder 4.0L applications. A multistage stainless mesh and honeycomb filter trap oil vapors and let clean air return to the intake; the removable base stores roughly 3 oz of fluid and should be drained every 2,000–3,000 miles to prevent buildup.
