Dinan High Flow Throttle Body - 1991-1995 BMW 325i/525i/M3

Dinan's High Flow Throttle Body improves intake airflow for additional horsepower and torque gains. The internal diameter of the stock throttle body has been increased for additional airflow area. The resulting increase in airflow provides more horsepower and torque throughout the RPM range with noticeably quicker throttle response. Core Program: This throttle body set is part of the CORE program we utilize at Dinan so the listed price includes a core exchange fee. This fee will then be refunded to you once your old throttle bodies have been received at Dinan and passed a quality check. This ensures we have a continuous stream of products for rebuilding purposes and the lowest possible price to the consumer. Any cores sent back that are damaged and/or unusable will not be given credit for. Please ensure adequate packaging and packing is being used to protect returning cores.
