The Radium Engineering Port Injection Fuel Rail Kit adds port injection capability to the direct injection K20C engine found in the Honda Civic Type-R FK8 and FL5. By supplementing the factory direct injection system with port injection, this kit enables E85 compatibility and significantly increases total fuel delivery capacity for high-horsepower forced induction applications where direct injection alone cannot meet fuel flow demands.
Note: Port injectors, fuel pump, and ECU tuning are required and sold separately. Professional installation and tuning is recommended.

- CNC-machined billet aluminium fuel rails
- Anodised finish for corrosion resistance
- Compatible with gasoline, E85, and all alternative fuel types
- All necessary mounting hardware included
