Convert your side-feed injector WRX STI to top-feed for better choice of injectors, better/smoother fuel flow, and improved safety.

Injector Dynamics provide the absolute best fuel injectors available, and have quickly become the standard for tuners and car builders worldwide. Injector Dynamics fuel injectors 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 pulsewidth range. The result is vastly superior cylinder to cylinder consistency, even at very low pulsewidths.

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.

Included with this kit is the clips and pins that fit the Injector Dynamics Injectors. You can either re-pin your factory harness or purchase the optional .

This kit comes with billet fuel rails to convert your side-feed equipped car to 1050cc top-feed injectors. The fuel rails have -6an fittings on each end to leave your plumbing options open. Works great with the .

Kit includes two billet aluminum top-feed fuel rails, four E85-compatible fuel injectors (choose 1050cc or 1300cc), billet fuel rail spacers and hardware, and wiring harness conversion pigtails.
