The 1300x is an all new injector, designed by Injector Dynamics in partnership with Bosch Motorsport*

This collaboration has given Injector Dynamics the ability to design a high flow injector with characteristics specific to the needs the high-performance tuner.

The 1300x 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 1300x was designed with an eye towards ethanol fueled engines, we have accounted for the occasional need to convert back to gasoline. The 1300x 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 1300x allows fitment in 200+ applications, making it the most versatile injector in the Injector Dynamics lineup.

Great Injectors (as always from Injector Dynamics)

I have never had any issues with an ID injector whether it be on a corvette, cts-v, or subaru wrx. Great idle and tuners love how precise they are

Very well thought out and easy

This is almost everything you need to convert from side feed to top feed. ID injectors have quickly become tuners favorite injectors. This kit contains the injectors, top feed conversion rails, mounting hardware, and new pins for rewiring. I did purchase the plug and play harness rather than repin my factory harness. The ONLY thing this is missing are fuel lines, but that's to allow you to route your fuel system any way you like. The rails use ORB threaded openings so you can use whatever your heart desires. Great kit and very well thought out.
