The most exciting EFI to date! Classic Retro Look with Modern Day Performance.

 Ideal for converting from Carburetion to Fuel Injection.

As EFI tuners and manufacturers we have taken our years of experience and technical assistance and developed a system incorporating all the factors missing in "Bolt On" systems currently available on the market. We have listened to the consumers and engineers. We build what we drive and drive what we build.


The new Boss EFI has taken a quantum leap in technology for aftermarket fuel injection systems. It is the least expensive and easiest to install of any full featured system, It is also one of the most technically advanced of any aftermarket EFI system. The features the Engine Management System (EMS) mounted directly onto the throttle body thereby eliminating 80% of the necessary wiring harness. The throttle body assembly includes the EMS, throttle position sensor, MAP sensor, idle air control, and four 62lb. /hr. port style injectors. The linkage on the side of the unit is identical to a Holley 4-barrel and the throttle body has overall dimensions that are the same as a 4150 style Holley. Read Kit Car Builder Article.

Despite the compact size of the EMS, it is still laptop programmable but for most vehicles the standard program is suitable. The EMS is self-learning which you can start the car up after installation, drive it around for 20 or 30 minutes and it dials itself in to the perfect tune. It continues to tune as it adapts to your driving style and conditions. SEE OUR COMPLETE BOSS EFI ENGINE PACKAGES.
