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.
