We have developed a port injection kit and LPFP upgrade (Low Pressure Fuel Pump) 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 fuel 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.
What is the Stage 4 LPFP upgrade?
This upgrade is an E85 compatible dual pump system that doubles the factory capacity and is required when looking to make more than 600whp on E85.
We supply the kit with black intake couplers as default, if you require red or blue please email us with your order number and specify the colour you wish to have.
