Every CARDONE Remanufactured Electronic Throttle Body undergoes a proprietary disassembly, inspection and renewal process. Each component is meticulously evaluated and then renewed or replaced, depending on whether the component meets our stringent engineering standards. A proprietary cleaning process prevents the throttle bore surface from deformity, ensuring optimum airflow. Every unit is tested for all critical functions, including response time and air flow at multiple points to ensure peak performance.
