Description
Exceptional Quality. The newly redesigned plenum is CNC machined from solid aluminum. Also, the exterior is polished to an eye-catching finish. Only the best components are used for unparalleled reliability and performance. Manufactured in the USA.
Better Air Flow for More Power. Independent dyno tests on a completely stock vehicle have shown an increase of up to 11 additional horsepower, with additional torque and no loss to bottom end performance, when used with an Accufab 70mm or 75mm throttle body and plenum. We have performed flow testing on a majority of plenums with the stock throttle body and an Accufab 70mm or 75mm throttle body.
Application. The plenum is specifically designed as a direct bolt on for use on the 1996 – 2004 Ford Mustang 4.6L 2V. Please contact us if you have questions about your non Mustang application.
- Accessories Included. The plenum includes a throttle body gasket, IAC gasket, EGR gasket, plenum tubes and TPS & IAC mounting screws.
(Prior to 2025, the old version was a cast product. The new version is not cast.)
