Genuine Authentic Siemens Deka 4 Mototron injectors are a new take on high impedance injectors. 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. Adding to the flexibility of application, these units are high-impedance; making them compatible with most ECUs, while delivering the most flow available in a High-Impedance injector.

These injectors are able to function at high fuel pressures and don’t exhibit the high fuel pressure handling problems found with many other high flow high-impedance injectors. 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. Unlike competitors “pencil stream” high flow injectors; these High Flow injectors utilize a multi-orifice tip providing a true 30 degree spray pattern for improved mixture preparation. This results in lower BSFC and better idle quality than many injectors with less flow.

These are the long style injectors with domestic style 14mm o-rings. These are NOT the knock off/copycat versions of these injectors that blow up your engine when they fail

The ECU dictates if you must run low or high impedance injectors. Stock 2.3 Turbos require Low Impedance. Our PIMPx can run either High Impedance or Low Impedance (4 cyl only). Our PiMPxs, PiMPxshift, and Microsquirt requires High Impedance. We are a big fan of the High Impedance Siemens units with our ECU's.
