Amp Performance Three Valve Hci Kit Racing Manifold
|
In this photo, Ford Racing Performance Parts' new intake manifold is on the left and the stock piece from our '08 test 'Stang is on the right. The major performance difference between the two is the deletion of Charge Motion Control Valve plates on the new manifold. While CMVCs help bring increased torque to Three-Valve modulars for improved low-rpm/street-cruising performance, they actually present a huge airflow restriction at higher engine speeds and thus limit performance considerably.
