PRL Motorsports Helix Air Oil Separator, Black | Honda Civic Type R FL5 2023-2025

The PRL Motorsports Helix Air Oil Separator, Black is engineered for the Honda Civic Type R FL5 2023-2025 equipped with the turbocharged 2.0L engine. This air oil separator system is designed to remove oil vapor, fuel residue, and moisture from crankcase blowby gases before they are routed back into the intake tract through the factory PCV system. By reducing oil contamination within the intake path, the system supports cleaner charge piping, improved intake valve condition, and consistent combustion performance in high-boost applications.

Helix Centrifugal Separation Design

The internal proprietary helix creates controlled centrifugal airflow inside the canister. As crankcase gases pass through the separator, heavier oil particles and moisture are forced outward toward the walls of the unit where they condense and collect at the base. The cleaned air is then returned to the intake system, maintaining closed loop operation and proper ECU fueling strategy.

This fully serviceable air oil separator requires periodic draining depending on driving style, boost levels, and environmental conditions.

Precision CNC Machined Construction

• CNC machined 6061-T6 billet aluminum canister
• Black hard anodized finish for corrosion resistance
• Billet aluminum fittings and integrated billet check valve
• Viton O-rings for long-term chemical resistance and durability
• Custom molded reinforced rubber hoses for turbocharged engine bay heat
• Laser cut and CNC bent 304 stainless steel mounting brackets

Honda Civic Type R FL5 2023-2025 Specific Integration

Designed specifically for the Honda Civic Type R FL5 2023-2025, this closed loop air oil separator integrates with factory PCV routing and emissions equipment without interfering with standard engine management functions. Select applications include a billet aluminum line clamp to secure hose routing and minimize movement within the engine bay. The PRL Motorsports Helix Air Oil Separator, Black provides a durable crankcase vapor management solution tailored to the performance demands of the FL5 platform.
