As the core component of the Honda S4 series electronic fuel injection system, these specialized fuel injectors deliver efficient fuel atomization and dynamic injection control through precise hole configurations and professional tuning for 100cc to 500cc models. They balance power output and fuel economy, revitalizing classic vehicles with optimized performance.
Core Technology: The “Power Hub” of EFI Systems
Fuel injectors precisely control fuel injection volume via electromagnetic pulses, adapting in real-time to engine conditions based on Honda S4 series ECU commands:
- Micron-Level Atomization Technology: Multi-hole design breaks fuel into ultra-fine droplets, enhancing air mixing efficiency by 40% for more complete combustion;
- Dynamic Response System: Millisecond-level needle valve actuation matches all scenarios—idling, acceleration, high-speed cruising—to ensure linear power delivery.
Diverse Hole Configurations: Tailored Performance Solutions
Offering 6/8/10/12/14-hole specifications for different displacements and riding scenarios, precisely adapted for CB100F, CB300R, CB500X, and other Honda S4 series models:
· 6-Hole Fuel Injector
Designed for balanced injection coverage with outstanding fuel economy, ideal for 100cc-150cc entry-level models. It achieves low fuel consumption and smooth low-speed performance in urban commuting, especially suitable for new riders seeking daily mobility with cost control.
· 8-Hole Fuel Injector
Finely atomized particles enhance mid-low speed power response by 20%, suitable for 200cc-300cc street bikes. Whether navigating frequent lane changes in the city or winding mountain roads, it provides more agile acceleration feedback, balancing handling and power.
· 10-Hole Fuel Injector
30% expanded injection surface significantly optimizes combustion efficiency, specially developed for 300cc-400cc sport models. It ensures uniform fuel atomization during mid-high speed cruising, improves explosive power, and reduces engine carbon buildup—perfect for riders chasing driving passion and long-range endurance.
· 12-Hole Fuel Injector
Ultra-fine atomization technology achieves linear power improvement while reducing fuel consumption by 10%, adapted for 400cc-500cc mid-large displacement models. It precisely controls fuel injection during high-speed cruising and maintains stable power output on complex roads, balancing performance and emission standards.
· 14-Hole Fuel Injector
Extreme atomization precision matches track-level tuning to maximize combustion efficiency, specially designed for 500cc performance models. Requiring higher fuel quality, it achieves dual breakthroughs in explosive power and fuel economy—ideal for professional riders or deep modification needs to unleash the vehicle’s ultimate performance.
