Gain 10+ HP. Replace your restrictive factory charge motion control plates with Steeda's free-flowing plates and enjoy more power and torque. These high performance plates add horsepower and torque in the mid to upper RPM ranges without sacrificing low end torque for the kind of tire-frying power you can feel. Peak gains of up to 10 horsepower have been seen on naturally aspirated Mustangs, and more power is possible from supercharged engines.
Designed to Perform. As used on Steeda's Q335 Mustang, these plates are 0.070 thicker than the factory plates and are a better port match to the intake manifold and cylinder heads than your OE plates to untap hidden horsepower. They also delete the factory butterfly flow control to reduce turbulence and increase airflow - and as everyone knows, more airflow equals more power.
Billet Aluminum. These premium quality plates are CNC machined for precision out of aircraft-quality 6061-T6 billet aluminum so they won't weigh you down.
Application. The Steeda Billet Motion Control Charge Plates are designed for the 2005 to 2008 Mustang GT and 2008 Bullitt with the 4.6L three valve V8 engine. These plates will require computer recalibration - we recommend a Mustang Handheld Tuner to reprogram the vehicles computer (ECU) for proper operation. .Note: As of the 2009 model year, Ford now molds the charge motion plates into the stock intake manifold. So they are not changeable.
Technical Notes. Will not work with 2009+ Mustangs.
