PRL Motorsports Helix Air Oil Separator, Silver | Honda Civic Type R FK8 2017-2021
The PRL Motorsports Helix Air Oil Separator, Silver is engineered specifically for the Honda Civic Type R FK8 2017-2021 equipped with the turbocharged 2.0L engine. This air oil separator system is designed to remove oil vapor, excess fuel, and moisture from crankcase blowby gases before they are recirculated into the intake system through the factory PCV routing. Reducing oil contamination in the intake tract helps maintain cleaner intercooler piping and intake valves while supporting consistent combustion performance in high-boost applications.
Internal Helix Separation Technology
This system features a proprietary internal helix that creates controlled centrifugal airflow within the canister. As crankcase gases pass through the unit, heavier contaminants are forced outward toward the walls of the separator where they condense and collect at the bottom. The cleaned air is then returned to the intake system, preserving closed loop operation and factory fueling behavior.
The design is fully serviceable and requires periodic draining depending on driving conditions, climate, and engine output levels.
CNC Machined Billet Construction
- CNC machined 6061-T6 billet aluminum canister
- Hard anodized silver finish for corrosion resistance
- Billet aluminum fittings and integrated billet check valve
- Viton O-rings for chemical resistance and long-term durability
- Reinforced rubber hoses designed for turbocharged engine bay environments
- Application specific laser cut and CNC bent 304 stainless steel mounting brackets
Vehicle-Specific Integration
Designed for the Honda Civic Type R FK8 2017-2021, this closed loop air oil separator system integrates with factory emissions equipment and PCV components without altering normal engine management functions. Select configurations include a billet aluminum line clamp to secure hose routing and limit movement within the engine bay. The PRL Motorsports Helix Air Oil Separator, Silver provides a durable crankcase ventilation solution tailored to the performance demands of the FK8 platform.
