I-M Shield significantly reduces the amount of heat transfer from the top of the engine to the intake manifold, helping to reduce air-intake temperatures and increase horsepower. Lower air-intake manifold temperatures create a denser air/fuel mixture, creating more power. Heavy-duty adhesive will stick to any clean, semi-smooth surface.
Simply degrease the surface, wipe with pre-paint cleaner or isopropyl alcohol, let it dry, then firmly press the I-M Shield onto the underside of the intake manifold. Use the provided edging tape to finish the installation of this intake manifold heat shield. I-M Shield is pre-cut for the 2012-2013 Boss 302 intake manifold (161 M 9424 M50BR) as well as 162 CR3Z 9424 A . Think of I-M Shield as an intercooler for your Mustang Boss 302 intake manifold, reducing the temperature of the air/fuel inlet charge for higher density and more power.1
