Injector Dynamics 1300cc Fuel Injectors Top Feed Subaru 2002-2014 WRX / 2007-2019 STI


SKU 1300.48.11.WRX.4
The ID1300 is an all new injector, designed in partnership with Bosch Motorsport. This collaboration has given us the ability to design a high flow injector with characteristics specific to the needs of the motorsport tuner. The ID1300 was designed with alternative fuels in mind, and is the only performance injector available with all stainless internals. It is compatible with all known fuels, and will stand up to the corrosive nature of alcohol better than any injector on the market.
While the ID1300 was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The ID1300 has a minimum fuel mass compatible with gasoline use, and will provide exceptional idle and cruise behavior under these conditions. In addition to its multi-fuel capabilities, the compact body of the ID1300 allows fitment in 200+ applications, making it the most versatile injector in our lineup.

Are you tired of pouring over logs, making corresponding changes to your tune, only to find that what worked one day is off by the next? Have you wasted hours sifting through a myriad of injector related forum posts, only to find that there is no simple solution? Such is the nature of tuning with inaccurate injector data.


Accurate injector characterizations are the basis of all fueling calculations, so it’s no wonder that if you’re tuning without them, you will spend a lot of valuable time making the best of a bad situation. It will keep you busy searching for endless combinations of mostly incorrect answers, and it will rob you of the most basic functions provided by the guys who spent millions of R&D dollars designing the engine management system for your car.

Whether you are a professional tuner, or an end user, you can spend countless hours getting it “mostly correct” or you can copy and paste accurate characterization tables and get on with the job of maximizing performance and drivability.


Injector Dynamics is the only motorsport injector supplier capable of generating these OEM quality injector characterizations, and our engineering services are available to generate data for new platforms and applications at no cost to our customers.


We welcome the opportunity to provide solutions where none previously existed, and it is this commitment to value and innovation that has earned us our position as the industry leader.

Remember that next time you hear “The Same as Injector Dynamics but Cheaper”
