Whipple Siemens Deka 63 lb/hr Short Fuel Injector Set – EV1, 34.5mm INJ-63S

Whipple Siemens Deka 63 lb/hr Short Fuel Injector Set

The Whipple Siemens Deka 63 lb/hr Short Fuel Injector Set is a high-impedance injector package designed for applications that need strong fuel delivery without sacrificing low-speed control. Sold as a set of 8, these injectors are well suited for performance builds that demand dependable flow, excellent atomization, and consistent drivability.

These injectors flow 63 lb/hr at 43.5 PSI (3 BAR) and can deliver even more at higher fuel pressure. Despite the higher flow rate, they remain linear and controllable at low pulse widths, making them a strong option for applications that need larger injectors without giving up idle quality and low-speed drivability. They are also compatible with most ECUs thanks to their high-impedance design.

These Siemens Deka injectors are built to function at high fuel pressures without the fuel pressure handling issues found in some other high-flow high-impedance injectors. That makes them a strong fit for turbocharged and supercharged applications that see elevated fuel system pressures, as well as many marine applications where this injector is commonly used.
