Fuel Injectors

Premium Remanufactured Fuel Injectors

Rotex Remanufactured Fuel Injectors meet or exceed OE standards because they’re remanufactured using processes similar to the way OEM Fuel Injectors are made. Components are gauged, sorted, tested and renewed to OE-quality specifications, and vital parts are replaced with new ones where needed. Every component and part must meet strict Rotex standards. Scheduled laboratory testing of fuel injectors from the assembly line includes loading the fuel injectors to an OE-quality specification. Instead of a “one-size-fits-all” approach, our test engineers make certain that each fuel injector is tested with the load specification for its particular applications. Because of this strict adherence to OE-quality, a Rotex Premium Remanufactured Fuel Injector installs quickly and easily, and provides fueling performance you can count on.
