Product Description

Bosch 550cc/min High Resistance Top Feed Fuel Injector.


This injector is ethanol E85 (flex fuel) compatible!


  • These fuel injectors are high impedance, therefore there is no need to add ballast resistors, which makes them compatible with most ECU’s.
  • “3/4 Length” injector which has a top spacer / adapter included to make the fuel injector standard length. This adapter can be supplied with a 11mm or 14mm top o-ring.
  • Excellent atomisation for multi-valve engines. Will function at fuel pressures up to 7 Bar, making them ideal for turbocharged applications.
