Description

The K-Tuned 74mm Drive By Wire Throttle Body (KTD-74D-RBC) is a performance upgrade designed for custom automotive applications. It features a 74mm bore, offering a larger flow capacity than stock throttle bodies, and utilizes a drive-by-wire system for modern engine control. It is a universal product, meaning it is not made for any specific car installation but can be adapted through custom work. The true 74mm bore at the butterfly is larger than comparable OEM units, potentially improving airflow and throttle response. Installation of the KTD-74D-RBC requires an engine management system, such as K-Pro, as it does not include a MAP port. It's important to note that this throttle body is not compatible with the OEM RSX/EP3 throttle cable; the K-Tuned Throttle Cable is recommended to ensure proper length and function. All necessary hardware, a gasket, and a throttle bracket are included with the unit. While this throttle body is a universal fit, users should consult with Heeltoe for advice if they are unsure about compatibility with their specific vehicle or setup.
