Set of 4 short to long injector cap adapters. Injector O-rings included.

Drop-in adapter harness for the switch to MPI EV14 (Multi-Port Injection) injectors on Audi 2.5 TFSI EVO DAZA engines fitted with EV1 connectors. Paired with the Bosch EV14 injectors from the 034Motorsport MPI kit, it allows safe E85 operation.

Plug-in harness bypassing the original injector resistor pack when using the 034Motorsport 7A EFI injector adapter kit.

Bosch EV14 550cc fuel injector, the highest-performing in the 034Motorsport range, with OEM-matching dual spray cones, ultra-fast response, tested up to 8 bar rail pressure. Fuel rail spacers not required on recent VW/Audi applications.

Bosch EV14 750cc fuel injector, the highest-performing in the 034Motorsport range, with ultra-fast response and best atomization on the market, tested up to 8 bar rail pressure. Fuel rail spacers not required on recent VW/Audi 1.8T applications with original short injectors.

EFI injector adapter set for the Audi 20V 7A 5-cylinder engine, allowing virtually any injector to be fitted to the stock rail, replacing the discontinued proprietary Hitachi injectors.

Complete EFI 7A injector adapter kit that upgrades failure-prone original injectors to modern high-impedance Bosch injectors. Exact fitment with original Hitachi injectors, more consistent flow and improved atomization.

Set of 5 short to long injector hold-down adapters, compatible with RS4 rail and other applications. Injector O-rings included.

Set of 6 short-to-long injector cap adapters, compatible with RS4 rail and other applications. Injector O-rings included.
