Overview

The Injector Dynamics ID1050X is a built-to-spec motorsport fuel injector, representing the latest evolution of the ID1000. Developed in partnership with Bosch Motorsport, it offers optimized operating parameters for tuners.

Compared to the previous ID1000 model, the ID1050X features corrosion-resistant internals for compatibility with all fuels and extended service life. Its compact body design allows fitment in over 200 applications, including those using short body injectors. An improved internal flow path increases output by 5% without compromising low-flow performance. The injector also boasts a stronger magnetic circuit for stable operation up to 10 bar and includes a replaceable inlet filter.
Show original supplier description
The Injector Dynamics ID1050X fuel injectors are a high-performance upgrade, offered as a set of four top-feed units. These injectors are designed to provide a normal flow rate of 1065cc/min at 3.0 BAR (43.5 psi) and 52° C (125°F), representing a 5% increase over previous models due to an improved internal flow path, all while maintaining exceptional low-flow performance. Developed in partnership with Bosch Motorsport, the ID1050X injectors feature all stainless internals, ensuring compatibility with a wide array of fuels including alcohol, ethanol, race fuels, and regular gasoline. The maximum differential fuel pressure is rated at 10.0 BAR (145.0 psi), and they come equipped with a USCAR electrical connector, along with included clips and pins. These injectors are specifically designated for off-road motorsport applications. This particular set is tailored for fitment in the 2002-2014 Subaru WRX and the 2007-2021 Subaru STI models.
