COMPATIBLE: (4.0L - S65B40)

2008 - 2013 BMW M3 

Dinan bores each of the M3's eight individual throttle bodies to a larger internal diameter, increasing the airflow area by a full 8%. The larger bore improves air-flow to the combustion chamber for further increases in power, as well as more immediate throttle response. The Dinan throttle bodies are matched on a Superflow Flow bench to ensure excellent drivability and faults will not be set. 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.
