82mm Bosch DBW Throttle Body Kit – 3” Power Clamp Connection
 
 
This FD-style upper intake manifold is designed to bolt directly to the FC RX-7 lower intake manifold, making it a popular upgrade for FC 13B engines. By utilising the improved intake design from the later FD RX-7, this manifold provides better airflow compared to the factory FC upper manifold, helping support increased horsepower in performance applications.
 
One of the main advantages of this setup is the cleaner engine bay layout it creates. The design allows additional space beneath the manifold, giving builders the option to mount ignition coils or other components neatly out of sight, resulting in a far more streamlined engine setup.
 
Ideal for performance builds, engine bay clean-ups, and modernising an FC RX-7 intake system, this manifold offers both functional and visual improvements over the standard factory configuration.
 
Features
 
FD-style intake design
Direct fit to FC RX-7 lower intake manifold
Improved airflow over the factory FC manifold
Supports increased horsepower potential
Creates space under the manifold for coil mounting
Cleaner and more modern engine bay appearance
 
Compatibility
 
Mazda RX-7 FC (13B engines)
Designed to suit FC lower intake manifold
Intended as an upgrade for FC RX-7 intake systems
Professional installation recommended
 
This kit combines the proven Bosch 82mm drive-by-wire throttle body with a billet adaptor and 3” Power Clamp connection, providing a clean and reliable solution for modern DBW throttle control on high-performance rotary and custom engine builds.
 
At the centre of the kit is the genuine Bosch 82mm electronic throttle body, widely trusted in motorsport and OEM applications for its reliability and precise control. To simplify installation, the kit includes a CNC machined billet adaptor designed to transition the Bosch DBW throttle body to a 3” inlet.
 
To complete the setup, a weld-on Power Clamp connection is included, allowing for a strong, leak-free and easily serviceable intake connection. This style of clamp is commonly used in performance applications where secure sealing and quick removal are important.
 
This combination provides a professional motorsport-style intake solution while maintaining the reliability of OEM Bosch drive-by-wire technology.
