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.

I M Heat Shield Review

Great product.. Fit well. I installed this heat shield on a Fast 102 intake in my 2012 Camaro SS. As well I used a Nick Williams 102 mm TB also from Pace Performance. I installed a stage 3 cam shaft and I don't believe I would've achieved the numbers I did without this heat shield. 516 rwhp and 464 rwtq on a mustang dyno. I recommend this heat shield to anyone looking to cool down your air / fuel mixture ... $53.00 is well worth the investment ... It's a no brainier.
