Agency Power 816CC Fuel Injectors (set of 4) Subaru STI

$225.99

With the testing of our HUGE STI turbo kit, Agency Power needed more fuel to overcome the factory 550cc injector limitation of 350 crank horsepower. With many STI owners wanting to push the limits of their STI, more fuel delivery is much needed. With several different options available, Agency Power has just released 2 new options for STI owners wanting more fuel for their higher horsepower cars at an affordable price.

The Agency Power STI Injectors flow 816cc. These injectors are designed for cars with large turbo kits making 400+ horsepower. We have these injectors available as brand new sets of 4. You can also send your original equipment injectors to us at Agency Power for modification for a small fee. Mail-in injector modification receives FREE overnight return shipping. Modification turnaround takes up to 24 hours from the receipt of the injectors.

Agency Power recommends a larger fuel pump when paired with this injector upgrade to compensate for the fuel delivery needed. For any other questions about this Agency Power product, please contact us appropriately.
