        Doesn’t come as a complete kit

        They sell them as a complete kit for a 2015 mustang gt but after you install them they need spacers and longer bolts to make the height difference. And I have a stock intake manifold.

      I have a procharged 2014 mustang gt. And was wondering if these will support enough flow for e85 on a stock block. Just trying to push between 6 to 700rwhp if possible. Or will I need higher flow rate for that? Thanks in advance

      • These injectors do have the ability to support that amount of horsepower, however, they are not E85 compatible, the injectors we would recommend going with are the DeatschWerks Mustang 78Lb injectors. These would provide enough fuel for that horsepower amount and are E85 compatible, the rest of the fuel system also has to be modified to run E85 however.

      These work with E85 right?

      • Yes, these work with E85 fuel.

      Will this work with 2014 5.0 with phase 3 Roush Supercharger bolt ons ?

      • These Fuel Injector Clinic Fuel Injector Set will work as long as the vehicle is tuned after the installation of the injectors.

      I been looking at different injectors and larger throddle body, I have a 2015 mustang gt 5.0 and I going to put catted headers on. Can you please advise me what would be a good combination? Thanks very much for your time. Hoping to hear from you soon.

      • The Fuel Injector Clinic Fuel Injector Set will be excessively large for the modifications you have listed. A 2015 With A CAI, Throttle body, headers and a tune will see no benefit from larger injectors, as you will not have moved past what the stock injectors can support. We recommend the BBK, or C&L 85mm Throttlebody for applications like yours.

      I have a 15 GT with the Ford Performance Pack 2 installed, which came with a tune. I see the Fuel Injector set comes in 3 different cc's (775cc, 1000cc, 1650cc). I would like to know which cc injector, if any, would be the best match for my current set up. And if installed, would I have to get another tune done by Ford Performance ( to keep my warrranty )? Any idea of what Horse Power gains I would be looking at? 1 answer
