550cc EV14 Single Hole Disc Fuel Injector

The Bosch 550cc EV14 fuel injector is engineered for high-performance needs, offering superior atomization and a wide cone spray pattern for optimal fuel delivery. Each injector is flow-matched in sets with new Viton o-rings, ready for installation. They are compatible with all fuel types, including gasoline, E10, and E85, and are designed for high resistance applications, eliminating the need for inline resistors or resistor boxes. These injectors boast a flow rate of 550 cc/min at 3 Bar (52 lbs/hr at 43.5 psi), with performance increasing at higher rail pressures (600 cc/min at 3.5 Bar, 649 cc/min at 4.0 Bar). They exhibit excellent low pulse width response, with predictable performance down to 2ms, and can function at rail pressures exceeding 101 psi (7 bar). The USCAR electrical connector ensures reliable connection. Installation may require specific adapters, such as the Bosch Jetronic to USCAR EV14 adapter, which are sold separately. For certain applications, like the 2.7T with an RS4 intake manifold and fuel rail, a complete installation kit may be necessary. It is important to note that these injectors are typically sold individually, so ensure the correct quantity is ordered for your specific application.
