Show original supplier description
The Injector Dynamics 1750-XDS fuel injectors are a set of four high-performance injectors designed to supplement the fuel system for moderate to significant performance enhancements. Engineered in partnership with Bosch Motorsport, these injectors are a top choice for experienced tuners seeking reliable fuel delivery for demanding applications. Key features include a 1750cc injector size (rated at 1725cc/min at 3.0 BAR) and a 48mm length with a Mach 11mm top. They utilize a Denso base with low-profile cushioning and are constructed with all stainless steel internals. This robust build ensures compatibility with a wide range of fuels, including alcohol, ethanol, race fuels, and regular gasoline, while maintaining exceptional idle and cruise behavior. These injectors are designed to work with alternative fuels and can handle a maximum differential fuel pressure of 7.0 BAR (101.5 psi). They feature a USCAR electrical connector and come complete with necessary clips and pins. While the injectors themselves are a direct fit for many Subaru WRX and STI models, please note that they may require adapters to be fully plug-and-play, and professional tuning is essential for optimal performance and engine health.
