The J&L Oil Separator 3.0 rear catch can is a billet unit that captures oil vapors before they contaminate intake passages, using fine stainless mesh and a honeycomb stage to condense droplets. Fluid collects in a removable 3 oz reservoir sealed with an O-ring and knurled base for quick draining. Built for durability with straightforward PCV hookups; drain every 2,000–3,000 miles. Fits 2013–2014 Ford Focus ST rear applications.
