Ford Duratec 2.5L Intake - 7000RPM Runner
Taking early fall 2026 batch orders! Manifolds ordered August 2026 are expected to be complete and ready to ship to customers in October of 2026.
This intake is configured for 2008 through 2019 Ford Duratec 2.5L engine. This engine is a common swap engine into 2005 through 2019 Mazda MX-5 NC. Runners are selected to favor peak power with a target of 7000RPM for peak torque. Exact results will depend on your exact engine and build. This intake comes with a traditional style (forward-facing throttle body) 2.5L plenum.
This intake is fully O-Ring sealed including the head flange and throttle body interface. You don't need any additional gaskets to install on your engine. This manifold also weighs under 8 pounds!
The Plenum has 6x -6 ORB ports for any vacuum or boost accessories you might need. Included fittings:
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.
The plenum also has two dedicated manifold absolute pressure (MAP) sensor location options. The Two MAP sensor options are:
Mazda NC MX-5 L3K9-18-211A or similar
Honda K20/K24 079800-7240 or similar
Either MAP option can be used or left blocked off depending on your application. Each sensor can be installed in one of 3 positions to position the connector in the ideal orientation for your application. Additionally, either of the unused MAP ports can be utilized as an additional -6 ORB vacuum or boost port using an optional adapter.
This manifold accepts all parts from our current and future intake manifold 2.0 sandbox of parts. This means that it can be reconfigured with a different head flange (such as the Mazda 2.0L MRZ), runners tuned for different peak power, different plenum style and volume, and accept the independent throttle body adapter.
This intake is proudly designed, machined, and assembled in the USA in our small North Carolina shop using primarily US-sourced materials. We welcome customization discussions. We try to keep parts in stock but not in large quantities. If we have all of the parts necessary to build your order, the order will ship within a couple of days. If we do not have the exact parts to build your order on the shelf, we will clearly communicate how long it will take us to make all of the parts needed.
The intake has provisions for the following drive-by-wire throttle bodies:
74mm Bosch 0280750474 drive-by-wire throttle body. For reference, this throttle body has a 70mm x 70mm bolt pattern using M6 hardware.
If you'd like to use another throttle body, such as the stock NC MX-5 throttle body or Bosch 68mm drive-by-wire throttle body, you'll need to purchase a dedicated adapter. Select that option at checkout or choose one on the throttle adapter page. Throttle body adapters attach to the front of the manifold plenum to convert it to work with virtually any option. If we do not offer a particular throttle body adapter, please reach out to us.
This intake is NOT for road use. It is NOT intended, designed, or certified to be used on any road vehicle.
