Part Number: 711
C & L Performance Cast Intake Manifold Upper Plenum for 1996-2001 GT Mustangs.
By raising the roof and re-contouring the floor, the air makes a nice, smooth sweeping transition over a much longer path before entering the lower manifold. To ensure the absolute best velocity, the core of our plenum (which determines the air path) was designed to maintain a consistent volume from the throttle body opening all the way to the lower manifold. This maintains good airflow velocity and smoother flow. For lightly modified vehicles you can see a gain of at least 8 rear wheel horsepower. More heavily modified vehicles can see anywhere between 11-15 rear wheel horsepower and up to 20 ft/lbs of torque. 50 state legal.
*For 2001 Mustang owners, check the diameter of your PCV hose. If it is larger than the other vacuum hoses on the plenum, use IMCL6 instead.
