FIC Highflow Injectors Boost Honda Civic Si Performance

Honda Civic Si owners seeking to maximize their vehicle's performance may find their engines constrained at high RPMs, as if held back by invisible limitations. This common issue often stems from factory fuel injectors that cannot meet the demands of performance modifications.

A specialized solution has emerged for 2012-2015 model years: the FIC (Fuel Injector Clinic) 1650cc high-flow fuel injector kit, designed specifically to overcome these power limitations and unleash the engine's full potential.

Key Features and Benefits
  • Enhanced Performance: The 1650cc injectors deliver significantly greater fuel flow than stock components, ensuring adequate fuel supply during high-load conditions. This results in measurable gains in horsepower and torque, particularly beneficial for forced induction setups like turbochargers or superchargers.
  • Precision Fuel Delivery: Advanced solenoid technology and precision manufacturing ensure consistent, accurate fuel spray patterns. Even at maximum flow rates, the injectors maintain optimal fuel atomization for efficient combustion while minimizing knock risk.
  • Vehicle-Specific Design: Engineered specifically for the 2012-2015 Civic Si, these injectors require no modifications for installation. Comprehensive flow data accompanies each set to facilitate precise ECU tuning.
  • Durable Construction: Manufactured from high-grade materials and rigorously tested, these components maintain stable performance even under extreme track conditions.
  • Seamless Integration: The design maintains full compatibility with factory systems, allowing straightforward installation without extensive vehicle modifications.
Technical Specifications
  • Flow Rate: 1650cc/min
  • Impedance: Low
  • Nozzle Type: Multi-hole
  • Fuel Compatibility: Gasoline, ethanol blends (including E85)
Installation Considerations

Professional installation and ECU calibration are strongly recommended to ensure optimal performance and reliability. Regular maintenance including fuel filter replacement is advised to maintain system integrity.
