The J&L Oil Separator 3.0 passenger-side unit for 2005–2015 Nissan Titan 5.6L traps oil vapors before they enter the intake, reducing contamination and fuel dilution common under boosted or high crankcase pressure conditions. Milled from solid billet aluminum with a knurled removable base and O‑ring seal, it uses a multistage screen and aluminum honeycomb to collect oil in a 3 oz reservoir; service every 2,000–3,000 miles.
