PRL Motorsports Helix Air Oil Separator, Silver | Honda Civic 1.5T 2022-2026
The PRL Motorsports Helix Air Oil Separator, Silver is designed for the Honda Civic 1.5T 2022-2026 equipped with the turbocharged L15 engine. This air oil separator system manages crankcase blowby gases by removing oil vapor, excess fuel, and moisture before they are recirculated into the intake tract through the factory PCV system. Limiting oil contamination in the intake path helps maintain cleaner intake valves, intercooler piping, and combustion stability in direct injected turbocharged applications.
Helix Centrifugal Separation Design
At the center of this air oil separator is a proprietary internal helix that produces controlled centrifugal motion inside the canister. As crankcase gases flow through the unit, heavier contaminants are directed outward toward the walls of the separator where they condense and collect at the base. The cleaned air is then routed back into the intake system, preserving closed loop operation and proper fueling behavior.
The system is fully serviceable and requires periodic draining depending on driving conditions, climate, and engine output.
