Accufab 96-04 Mustang 4.6l 2v Polished Cnc Plenum

This Accufab Plenum is specifically designed as a direct bolt on for use on the 1996 - 2004 Ford Mustang 4.6L 2V. *Notice Accufab updated this part in Late 2024, it is now CNC machined from solid billet aluminum instead of the old cast aluminum in the past.
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. Accessories Included. The plenum includes a throttle body gasket, IAC gasket, EGR gasket, plenum tubes and TPS & IAC mounting screws.
