  • 1/2in Adapter Included: Fits 1/2in O-ring boss fuel rails ensuring leak-free seal and easy install on stock or aftermarket setups.
  • High-Impedance 12 Ohm: Works with stock ECUs and most aftermarket systems without resistor boxes for hassle-free operation.
  • Durable Brass Housing: Resists corrosion and wear for daily driving and track use with long service life.

Product Notes

  • ECU tuning required after install to adjust fuel maps for larger injector size.
  • Inspect O-rings and seats during install to prevent leaks.
  • Packaged in foam-lined box to protect components during transit.

Installation Notes

  • Professional installation recommended.
  • Remap ECU or add fuel management system like Hondata for proper scaling.

Fuel Injectors - Single

Fuel Injectors - Single

Purchasing a single fuel injector is the right approach when diagnosing and replacing a confirmed failed unit in an otherwise healthy set, or when building a custom EFI system that requires individual injector placement in a fabricated intake manifold or throttle body. A single injector replacement is commonly performed after a misfire diagnosis isolates one cylinder's injector as the root cause, avoiding the cost of a complete set replacement when only one unit has failed. For custom EFI builds using individual throttle bodies or single-point injection conversions, sourcing matched single injectors allows precise flow-rate targeting per cylinder independently. Whether repairing a daily driver or building a custom engine, having access to individual injectors at the correct flow rate and connector spec is essential. Popular Upgrades Top-selling single fuel injectors include Bosch OEM-replacement EV6 units for late-model domestic and import EFI applications, Siemens Deka 60-pound and...
