Product Description

Fuel has, is, and always will be the most limiting factor of any direct injection platform. Some OEM’s have resorted to using a combination of direct injection (DI) and port injection (PI) in order to meet the demands of higher horsepower. Most people resort to using water/methanol injection systems which can be un-reliable, inaccurate, and costly to refill on a regular basis.

Our fueling kit is designed to work with a secondary fuel rail mounted to your cold pipe just before the throttle body. By using a standard fuel injector, you are able to precisely inject an exact amount of fuel as opposed to a W/M injection kit which just pushes fuel through an orifice at a pre-calculated rate. By using the Split Second AIC, you are provided with a 3D table in which you can reference MAF voltage and RPM in order to inject fuel exactly when you need it.

Our kit also includes a direct fit, drop-in upgraded fuel pump to replace the stock in-tank fuel pump. We also replace the fuel lines under the hood with -6AN lines for full flow to the secondary fuel rail and then out to the CDFP. This allows un-restricted flow from tank to injector compared to some of the other kits on the market which utilize a restrictive and leak-prone adapter for the stock fuel line.

This kit also includes 2 Bosch high impedance 1000cc injector’s. These are not modified 500cc injectors that flow 1000cc’s, but actual factory Bosch 1000cc injectors. They have a 30 degree cone shaped spray pattern which provides instant atomization as the fuel exits the tip of the injector. They also have an extended tip which allows the injector nozzle to reach down into the intercooler piping to ensure that fuel is directly mixed with the surrounding air.

We also recently added a Plug-N-Play harness option for the coil packs! Now you dont have to cut and splice your coil pack harness to wire in the split second fuel controller. Just plug in the harness to all 4 coil packs and then plug the controller into the harness and thats it!

There has been much debate about the type of hose to use for applications that require resistance to corrosive fuel such as ethanol, methanol, and certain types of race gas. Our kit utilizes a synthetic rubber hose from Aeroquip that has a rating of “excellent” which means that ethanol has little to no effect on the degradation of this hose. Most other manufacturers will tell you their hose is “compatible” with ethanol but should be checked regularly for signs of wear. You can be sure that we went the extra mile to bring you a product that will last for years to come.

The full contents of this kit Include:

  • All necessary Russell/Aeroquip AN fittings
  • Aeroquip E85 rated fuel hose
  • 1 DeatschWerks 265LPH Fuel Pump
  • 2 Bosch 1000cc Injectors
  • Split Second Fuel Injector Controller
  • 9 inch long, 3” diameter pipe 
  • Dual Injector Boss
  • Reducing coupler for stock throttle body (3" to 2.75") 
  • Reducing coupler for intercooler piping (3" to 2.5")
  • Stainless Steel T-Bolt Clamps
  • Full Color Instructions


We recommend using this serial adapter if you do not already have one.




Note: These kits are typically made to order and can take anywhere between 1-3 weeks to produce.
