These Ultra-Compact, high flow injectors are just 40mm from the midle of the top o-ring to the middle of the bottom o-ring.

These high impedance injectors flow 60 lbs/hr at 43.5 PSI ( 3 BAR ). Despite the high flow rate, they are linear and controllable at low pulse widths. This allows you to use a larger injector than normally possible without hurting idle and low speed driveability.

Being high-impedance makes them compatible with most ECUs.

These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems which makes this makes these injectors very well suited to turbocharged and supercharged applications that see high fuel system pressures.

Engine performance and running quality are enhanced through the optimized spray pattern. They utilise a multi-orifice tip providing a true 26 degree spray pattern for improved mixture preparation. This results in lower BSFC and better idle quality than many injectors with less flow.

They fit into Holden LS3 engines where the short injectors are required. You will need to change the wiring connector though, look through related items for the correct connector for your requirements.
