EV14 550cc Fuel Injector

The Bosch EV14 550cc fuel injector represents the most advanced offering from Bosch in this line. These injectors have been rigorously tested and are confirmed safe for use with up to 8 bar of rail pressure. For later VW/Audi applications, fuel rail spacers are not necessary. However, please note that an Injector Connector Adapter (Bosch Jetronic to USCAR EV14) is required if your vehicle uses Bosch Jetronic connectors; these adapters are sold separately. Additionally, if you are installing these injectors on a 2.7T engine with an RS4 intake manifold and fuel rail, a complete installation kit is available. These injectors are sold individually, so ensure you order the correct quantity for your specific engine application. Fitment is confirmed for specific Audi models including the B5 A4 1.8T (FWD and Quattro) and the B5 S4 2.7T. Always use the vehicle selector to confirm exact fitment for your application.
