PRL Motorsports Helix Air Oil Separator, Black | Honda Civic 1.5T 2022-2026
The PRL Motorsports Helix Air Oil Separator, Black is engineered for the Honda Civic 1.5T 2022-2026 to manage crankcase ventilation in turbocharged direct injection applications. This air oil separator system removes oil vapor, fuel residue, and moisture from blowby gases before they are routed back into the intake tract through the factory PCV system. Reducing contamination in the intake path supports cleaner intake valves, improved intercooler efficiency, and consistent combustion characteristics over time.
Helix-Based Centrifugal Separation
Inside the canister is a proprietary internal helix that generates controlled centrifugal airflow. As crankcase gases pass through the separator, heavier oil particles and moisture are forced outward to the walls of the canister where they condense and collect at the bottom of the unit. The cleaned air is then returned to the intake system, maintaining proper closed loop operation and factory fueling strategy.
The system remains fully serviceable and requires periodic draining based on operating conditions, boost levels, and climate.
