Injector Dynamics provide the absolute best fuel injectors available and have quickly become the standard for tuners and car builders worldwide. These are the ID1050X fuel injector, are the result of batch testing large quantities of specially modified fuel injectors, and then carefully matching them into sets based on their dynamic flow across the pulse width range. The result is vastly superior cylinder to cylinder consistency, even at very low pulse widths. The X-Series is the result of the latest partnering between Injector Dynamics, and Bosch Motorsport. This injector is a new evolution of the ID1000.

In addition to receiving tightly matched injectors, you will be provided with dead time compensation values across the entire pressure and voltage range of the injector. This data will insure that the compensations in your ECU work properly, and your air fuel ratios will remain consistent as atmospheric or voltage conditions change.

Additionally, included are a pair of Injector Dynamics Billet Fuel Rails

Also included with this kit are the clips and pins that fit the Injector Dynamics Injectors. You can either re-pin your factory harness or purchase the optional plug and play adapters.

Sold as a set of 4 injectors with a pair of fuel rails and hardware to install the rails.

Fitment: 2004-2006 Subaru STI, 2005-2006 Subaru Legacy GT
