The J&L Oil Separator 3.0 Passenger Side is a direct-fit PCV system upgrade designed specifically for the 2021-2024 Ram TRX and its supercharged 6.2L Gen 3 HEMI. By capturing oil vapor carried through the PCV system before it reaches the intake tract, the separator helps reduce the amount of oil that can accumulate inside the intake tube and manifold. Its solid 6061 billet aluminum construction provides a durable, high-quality solution that fits naturally into both stock and modified TRX engine bays. OEM-style quick-connect fittings make installation plug-and-play, eliminating the need to cut or permanently modify factory PCV lines. With a 3-ounce collection capacity and an optional extension that doubles capacity to 6 ounces, the J&L 3.0 is a practical supporting upgrade for daily-driven, off-road, and high-performance TRX builds.

The PCV system routes crankcase pressure back through the engine’s intake system. During this process, suspended oil vapor can travel with those gases and accumulate throughout the intake tract. J&L notes that this issue can become more pronounced on forced-induction engines because supercharged and turbocharged applications can generate increased crankcase pressure. For the TRX’s supercharged 6.2L HEMI, an oil separator provides an additional stage between the PCV system and intake to collect that suspended oil before it continues downstream.

Inside the J&L separator is a multi-stage filtration system. Incoming vapor first encounters a fine stainless steel mesh screen, which captures fine oil vapor and allows it to collect into larger droplets. The oil then passes through a 1/2-inch-thick aluminum honeycomb filter with 1/16-inch passages, allowing the droplets to grow heavier and fall into the reservoir instead of continuing through the intake.

Serviceability is another benefit of the J&L 3.0 design. The billet reservoir features a knurled base that provides additional grip when removing the bottom section for draining, while an O-ring seals the assembly. J&L recommends initially checking the separator after approximately 500 to 1,000 miles to determine an appropriate service interval for your particular engine and driving conditions. The manufacturer also recommends draining the reservoir approximately every 2,000 to 3,000 miles based on typical use.

For owners who want additional capacity, this TRX-specific separator is compatible with J&L’s reservoir extension. Adding the extension increases total capacity from 3 ounces to 6 ounces, making it an option for owners who prefer additional collection capacity between services.

Installation uses OEM-style quick-connect PCV fittings for a clean, factory-like appearance without unnecessary modifications. The original factory hose can also be retained if the vehicle is ever returned to stock. This makes the J&L Oil Separator an excellent supporting modification for everything from an otherwise stock TRX to pulley, tuning, fueling, camshaft, and higher-output supercharged HEMI combinations.

For TRX owners looking to support the long-term cleanliness of their 6.2L HEMI’s intake system, the J&L Oil Separator 3.0 combines effective vapor filtration, straightforward servicing, quality billet construction, and vehicle-specific fitment in one simple upgrade.
