The J&L 3.0 Driver-Side Oil Separator, part number JLT3011D-B, helps protect the intake system of 2011-2017 Ford Mustang GT models by capturing oil vapor before it can accumulate in the intake tube, manifold runners, or combustion system. Crankcase vapors are common on all engines and can become more pronounced in supercharged or turbocharged applications. By separating suspended oil from the PCV airflow, this oil separator helps keep the intake tract cleaner and supports more consistent air and fuel performance.
The separator is machined from solid billet aluminum for durable, long-term service and finished with a black anodized coating. Its removable, knurled tank base makes draining convenient, while the O-ring seal helps prevent leaks. The multistage filtration system uses a fine stainless steel mesh screen to capture small oil droplets, followed by an aluminum honeycomb filter that encourages vapor to condense and fall into the collection chamber while allowing cleaner air to continue through the intake system.
Designed for straightforward installation, the J&L oil separator includes quick-connect PCV fittings and fits the driver-side PCV system on compatible Mustang GT applications. The collection chamber holds up to 3 fluid ounces and should be inspected and drained regularly, typically every 2,000 to 3,000 miles depending on driving conditions and vehicle setup. This product is intended for automotive use and is not CARB approved.
