Are you running more E85 or making more power on pump gas than your HPFP (High Pressure Fuel Pump) can support?

We have developed a port injection kit for your S55 that will provide you with the additional fueling capacity that you need to be able to run up to 100% E85 on stock or upgraded turbos.

What is port injection?

Port injection is a kit that is installed between your intake manifold and the cylinder head that runs off the low pressure supply to provide you with more fueling than your stock system is capable of. It’s a relatively easy system to install and does not require any permanent modification to your car.

We offer our port injection kits in five different packages to meet your needs:

*These kits are available for off-road use only

*Ethanol Sensors don’t actually read the ethanol content, the readings are based on the absence of gasoline, so if your fuel is contaminated, your ethanol readings may be artificially elevated.
