Description

The biggest problem in increasing horsepower on the factory Subaru Boxxer engine is the fuel delivery. The factory system runs the fuel in series which tends to cause certain cylinders to obtain less fuel. In higher boost applications, these cylinders can lean out dangerously causing the motor to fail. 

The new fuel rail system features -6 lines which is nylon coated in either red or blue. The lines feature AN fittings for a secure fit guarantying you will never have any leak issues. The new distribution block is mounted to the pitch stop mount under the top mount intercooler or front mount intercooler piping. Equal length line runs to each fuel rail to ensure proper fuel distribution for even the most powerful cars on the road. The new rail design features a 2 piece system that bolts in place of your factory unit. The rails seat securely on the injectors with the proper angle for the best and most precise spray pattern. The factory fuel pressure regular remains in the stock location and a return hose is used from the distribution block.

All 3 pieces are precision machined CNC 6061 aluminum. They have then been sand blasted and anodized in either red or blue for a smooth show finish. Each distribution block features the AP logo laser engraved. All fuel rail kits include the hardware and bracket for safe mounting.

The Agency Power Fuel Rail Kit works with all Subaru WRX & 2007 STi motors only. Top feed injectors work only for this kit like the factory setup.
