J&L 3.0 Passenger Side Oil Separator (Oil Catch Can) for 2015-2023 Hellcat, Demon, Durango Hellcat & Jeep Trackhawk

Keep your supercharged Gen 3 HEMI performing at its best with the J&L 3.0 Passenger Side Oil Separator. Designed specifically for 2015-2023 Dodge Challenger Hellcat, Charger Hellcat, Demon, Durango Hellcat, and 2018-2021 Jeep Trackhawk applications, this premium oil separator captures oil vapor and contaminants before they can enter the intake system. By reducing oil accumulation inside the supercharger, intake manifold, throttle body, and intercooler, the J&L 3.0 helps maintain engine efficiency, preserves horsepower, and supports long-term reliability. Whether your vehicle is stock or heavily modified, an oil separator is one of the simplest upgrades you can make to protect your investment.

Every supercharged Gen 3 HEMI produces crankcase blow-by during normal operation. Through the factory PCV system, oil vapor is recirculated back into the intake where it can coat the supercharger rotors, intercooler bricks, intake runners, and valves. Over time this oil buildup can reduce intercooler efficiency, lower octane tolerance, contribute to carbon deposits, and diminish overall engine performance. The J&L 3.0 Passenger Side Oil Separator intercepts these contaminants before they reach the intake tract, allowing only clean air to return to the engine.

The updated J&L 3.0 design incorporates an advanced multi-stage filtration system that effectively condenses and separates suspended oil from crankcase vapors. Internally, the separator uses a finely engineered baffling system that promotes maximum oil collection without restricting airflow through the PCV system. Unlike universal catch cans, this system is engineered specifically for the factory PCV routing found on supercharged Gen 3 HEMI applications, ensuring proper function and OEM-quality fitment.

Installation is completely bolt-on with no drilling, cutting, or permanent modifications required. The kit includes vehicle-specific mounting hardware, preformed hoses, and factory-style quick-connect fittings for a clean installation that looks right at home under the hood. The billet aluminum canister is fully serviceable, allowing collected oil to be drained periodically with minimal effort during routine maintenance.

For enthusiasts running smaller supercharger pulleys, custom tuning, E85, upgraded throttle bodies, higher boost levels, or frequent drag strip use, an oil separator becomes even more important. Increased cylinder pressure often creates additional crankcase vapor, making oil control essential for maintaining consistent performance. By helping keep the intake tract cleaner, the J&L 3.0 supports more consistent airflow, improved combustion efficiency, and helps preserve the performance of expensive aftermarket components.

Whether you’re daily driving your Hellcat or building a high-horsepower Gen 3 HEMI for street or track use, the J&L 3.0 Passenger Side Oil Separator is an excellent preventative upgrade that helps extend engine life while maintaining peak performance. Pair it with your regular maintenance schedule for maximum protection, and browse our Gen 3 HEMI Engine category for additional oil system upgrades, PCV components, and performance accessories to complete your build.
