High Flow Throttle Body Set

The Dinan High Flow Throttle Body Set is designed to enhance the performance of the 2008-2013 BMW M3 with the 4.0L S65B40 engine. Dinan meticulously bores each of the eight individual throttle bodies to a larger internal diameter, achieving an 8% increase in airflow area. This modification facilitates improved airflow to the combustion chamber, leading to noticeable gains in power and a more immediate throttle response. This throttle body set is part of Dinan's CORE program, which involves a core exchange. The listed price includes a core charge that will be refunded upon receipt of your old throttle bodies in acceptable condition. This process ensures a continuous supply of products for rebuilding and offers the consumer the lowest possible price. Cores returned that are damaged or unusable will not receive credit. Performance enhancements include a maximum gain of 7 HP at 8000 RPM and 5 lb-ft of torque at 3900 RPM. The throttle bodies are precisely matched on a Superflow Flow bench to guarantee excellent drivability and prevent fault codes. This product is a clearance item and all sales are final.
