Steeda's patented CNC machined billet charge motion plates are a superior upgrade for your 4.6L S197 Ford Mustang GT or Bullitt. As used on Steeda's Q335 Mustangs, Steeda's CMCP plates are. 070 larger than the OE plates and are a better port match to the intake manifold and cylinder heads than the original charge motion control valve system (CMCV) , reducing turbulence and improving airflow in the intake path for more horsepower and torque!

Beautifully CNC'd machined out of 6061-T6 aluminum for superior strength and light weight. Steeda's charge motion plates can be drilled and tapped for nitrous fitting holes on custom nitrous applications. Steeda's charge motion plates require computer recalibration for use. Once tuned, charge motion plates will not sacrifice any low-end torque and provide mid-range and upper RPM horsepower and torque increases. Peak increases of 10 horsepower or more have been seen on naturally aspirated applications, larger gains possible on supercharged engines.

Bolt them on now and maximize your power curve today!

Note: As of the 2009 model year, Ford now molds the charge motion plates into the stock intake manifold, so they are not changeable.

Increased hp
2005 Mustang GT with a Vortech SC, one of the best add-ons as it takes away the restrictive plates. I immediately felt the throttle response improve and the hp increase of 10-15 and this is seat of the pants feeling. The only drawback is that I am throwing a P2015 code even even after connecting the electrical connector for the actuator motor.

Excellent Product
I installed a set of billet Charge Motion Control Delete plates on my 2005 Mustang GT during installation of my supercharger. Excellent constructed quality product. No machining marks or burrs. The intake ports are smooth and completely even. Installation is simple- remove the plastic manifold plenum, unbolt the factory plates and bolt the Steeda plates in.
