The Stratified Auto auxiliary fueling system for the Fiesta ST 1.6L Ecoboost is a sure fire way to making much more power. With the limitation of flow in the direct injection system, there is only so much power you can make with the original, factory fuel system that comes on the car. In order to make more power and add more fuel to the engine in addition to what the factory injectors can flow, you must add more fuel. The Stratified system is a complete solution for this and includes the mounting system for the single extra injector, the proper hardware to feed it fuel, and the electronics to support the tuning required to run the new injectors. It's a relatively easy system to install and requires some basic tools and not much time under the hood. In addition to the extra power, the valves will now stay much cleaner with the new traditional style port injection system because of the fuel now passing along the back of the valves to enter the cylinder.
Stratified's auxiliary fueling kit includes a beautiful CNC machined billet aluminum spacer that sits in between the throttle body and the intake manifold to provide a location for the injector to spray fuel into the intake stream. A nylon braided E85 compatible fuel line connects to the the fuel rail and delivers fuel from the factory feed location via a fitting installed in between the factory line and the feed to the high pressure fuel pump.
Tuning is REQUIRED and this system cannot be utilized without the proper ECU calibration. Stratified Auto offers this service directly.
