Once you start performing any sort of modification that increases horsepower such as an upgraded intake system, full turbo back exhaust, or even a manual boost controller, you are surpassing the limits of your factory fuel injectors. These are COBB Tuning's 1300CC Top Feed Fuel Injectors, and have been designed to be a direct replacement of your factory injectors that will fit with your stock fuel rails to supplement the right amount of fuel for your modifications. 

These injectors have a normal flow rate of 1340CC/min, and they will come as a matched set with a dynamic flow rate variance within 1%. These injectors will come with a 14NN bottom O-ring, and there will be data supplied for tuning these injectors with Accesstuner Software. 

These injectors are compatible with pump gas, race gas, as well as E-85.

    i bought these a while ago and and changing to another motor where can i get new seals bottom and top

    • A: These injectors are relabeled Injector Dynamics injectors so you will need their o rings. If you give us a call when you are ready, we can get the correct ones for you.
