Siemens 80lb High Impedance Fuel Injector

The CTS Turbo Siemens 80lb (870cc) High-Impedance Fuel Injector is engineered for performance applications requiring increased fuel delivery. This injector flows 80 lbs/hr at 43.5 PSI (3 BAR) and can handle higher fuel pressures, making it ideal for demanding turbocharged and supercharged engines. These injectors are based on the Siemens DEKA IV (DEKA 4) design, known for its reliability and excellent response characteristics. Despite their high flow rate, they maintain linearity and controllability at low pulse widths, ensuring smooth idle and low-speed driveability. The high-impedance design ensures compatibility with most ECUs and factory injector drivers. Key specifications include a static flow rate of 80lb/hr (875 cc/min), dynamic flow rate of 18.6 mg/pulse, a coil resistance of 12 Ohms, and a Bosch EV1 connector. They also feature Viton O-rings for enhanced durability. The design is robust and capable of functioning well under high fuel system pressures. These injectors are a direct fit for most VW and Audi applications, though some engines may require spacers. Machining and harness adapters are necessary for use with MK4 24V and MK4/5 R32 models.
