Who doesn't want an extra nearly 20 horsepower, and 10 extra pound-feet of torque? And what if that extra power cost less than $100, and could be installed in under an hour? Well, say hello to your new best friend: Heatshield Products I-M Shield™!
I-M Shield simply attaches to the underside of the intake manifold via its specially formulated adhesive backing that can withstand temps to a sustained 300 degrees Fahrenheit. I-M Shield creates a thermal barrier between the intake manifold and the top of the engine, minimizing heat to the intake manifold. Even modern composite intakes are susceptible to heat soak, and the heat can raise the air temps inside the intake, costing horsepower and torque. By keeping intake air temps cooler, the computer is less prone to reducing ignition timing and/or increasing the air/fuel ratio, which decreases horsepower, torque and throttle response.
On any modern electronic fuel injection engine, when a
