2.5L Center Inlet Plenum
This is a center inlet style (side facing throttle body) 2.5L plenum. Each side of this plenum is CNC machined then TIG welded to form the completed part. Internally, each runner has a machined velocity stack. The Plenum has 6x -6 ORB ports for any vacuum or boost accessories you might need. Included fittings are:
4x -6 ORB plugs
2x -6 ORB to 3/8" Barb fittings. These fittings are provided for PCV and break booster vacuum sources.
4x M6x35mm studs and M6 nuts are included for throttle body installation.
Plenum has provisions for the following two drive by wire throttle bodies:
76mm Ford/Mazda CA-01-13-640 (or cross referenced PN) commonly used on Mazda CX9
71mm Ford DS7Z-9E926-D (or cross referenced PN) commonly used on Ford 2.5L inline 4 engines from 2009-2025.
To run either of these throttle bodies you will need to have a standalone ECU which can support drive by wire AND proper wiring provisions installed. Consult your ECU manufacturer and engine tuner for compatibility and installation.
If you would like to use another throttle body, you will need to purchase a dedicated adapter by visiting our throttle adapter page.
