AZSPEED is the leader in high performance electronic fuel injection for automotive, marine. We have developed components to complement your existing EFI system or we can provide complete systems.
AZSPEED is constantly developing new products to complement our line of performance components. The electronic fuel injection systems allow us to control several parameters including fuel delivery, spark timing, and engine operating temperature. These parameters are "read" by the computer through the use of several sensors that monitor engine operations and functions. The computer analyzes the engine information and makes changes based upon optimum performance, fuel economy and driveability.
Our staff is comprised of highly qualified individuals who have the combined expertise to develop and produce the very best after-market fuel injection components available. Our team has the dedication and creativity that has kept our designs a step ahead of our competitors. New concepts and ideas are constantly changing the way electronic fuel injection has evolved; making our work challenging and gratifying.
