Are you running more E85 or making more power than your stock fuel system can support?

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.
