Our goal is to provide retrofit fuel injection systems for aftermarket applications which are affordable, unique, and consistent with the customer’s individual needs.

Affordable Fuel Injection (AFI) was founded in 1997 with one goal in mind: offer fuel injection systems that allow superior performance to traditional carburetor systems, for a variety of applications, and make it affordable. The foundation of AFI is expertise. This expertise comes from over 35 years of combined experience in both OEM and aftermarket automotive design and development.  AFI’s owner is retired from a major automotive manufacturer where he has developed fuel injection systems from the simplest to some of today’s most advanced controls.  AFI’s expertise is unmatched in the automotive aftermarket and you can trust us to provide everything necessary to add fuel injection to your project.

Affordable Fuel Injection is currently developing many exciting new products that are unprecedented in the automotive aftermarket. We are developing a proprietary engine controller as well as a unique new throttle body that will be able to replace current “core and used” throttle body injection units. Whether you are considering fuel injection for industrial use, street rod, off road, marine or any other application, AFI has a solution for you.
