Description

The Injector Dynamics ID1050X fuel injectors are a high-performance upgrade designed to deliver precise fuel delivery for demanding applications. Developed in collaboration with Bosch Motorsport, these top-feed injectors boast a 1050cc capacity and feature an advanced internal flow path that enhances output by 5% without compromising low-flow control, ensuring excellent idle and cruise characteristics. Engineered to be compatible with a variety of fuels, including alcohol, ethanol, race fuels, and standard gasoline, the ID1050X injectors offer versatility for different tuning setups. Their normal flow rate is rated at 1065cc/min at 3.0 BAR (43.5 psi), with a maximum differential fuel pressure capability of 10.0 BAR (145.0 psi). Each set includes four injectors, USCAR electrical connectors, and stainless steel terminals. Installation of these injectors requires custom tuning to ensure optimal performance and engine health. Additionally, the factory wiring harness will need to be modified, as the stock connectors must be cut off to adapt to the new USCAR connectors. This product is sold as a set of four injectors and does not include fuel rails.
