Overview

The Injector Dynamics ID1300x² is a high-flow electronic fuel injector designed in partnership with Bosch Motorsport for motorsport tuners. Originally developed for alternative fuels, it features all stainless internals for superior corrosion resistance against alcohol-based fuels.

Key specifications include a nominal flow rate of 1335cc/min @ 3.0 Bar (43.5 psi) and a maximum differential fuel pressure of 7.0 Bar (101.5 psi). The electrical connector is USCAR, and the injector length is 48mm. It uses 12mm ID and 14mm OD o-rings.
