Stick on horsepower! I-M Shield can increase horsepower (up to 12 RWHP!). It works by shielding the intake manifold and reducing the heat radiating up from the top motor. This lowers intake manifold temperatures creating a more dense fuel and air mixture, creating more power. Think of it as an intercooler for your intake, same physics and chemistry just a different way to get there. Heavy duty adhesive will stick to any clean semi-smooth surface. Simply degrease, then clean surface, then wipe with pre-paint cleaner or isopropyl alcohol, let dry then firmly press the I-M Shield onto the underside of the intake manifold. Use provided edging tape to finish the install. I-M Shield comes pre-cut but may be trimmed with heavy scissors or utility knife! Get your I-M Shield and add some Instant-Muscle and blow the competition away.
