  • AUS Injection was founded in 1997 in Mesa, Arizona providing fuel injector cleaning and remanufacturing services for local professional installers. Tremendous product demand allowed us to relocate to a larger production facility in Tempe, Arizona in 2005.


    After developing our successful nationwide Aftermarket Wholesale Program for Warehouse Distributors and Major Retailers in the U.S. and Mexico, high demands for our Fuel Injectors necessitated additional expansion once again. We now utilize over 20,000 sq. ft. of Production, Warehousing and Office space.


    AUS Injection is the first to market a comprehensive line of High Performance Injectors. Our HP Injector program was developed with assistance from Professional Race Teams and Performance Tuners around the world. Our proprietary remanufacturing techniques and State-of-the-Art equipment allows AUS Injection to proudly offer the industry’s most comprehensive World Class Fuel Injector program.
