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 available pre-cut for certain applications and in a universal kit that may be trimmed for a custom fit. Think of I-M Shield™ as an intercooler for your LS intake manifold, reducing the temperature of the air/fuel inlet charge for higher density and more power.

Q. Do I need to remove my factory foam on my intake manifold, and how do I do so?

A. Yes, you do need to remove any factory foam underneath the intake manifold. The I-M Shield must stick to a hard surface in order to maintain a long lasting bond. Peel the foam off, clean it good with carburetor spray or other degreaser, wipe with pre-paint cleaners and stick.


 Q. How does it create more power if the because the MAF and IAT sensors are before the IM Shield?

A. Any reduction in intake temperatures creates more power, regardless of sensor location. additionally, the O2 sensor downstream helps the ECU adjust for the cooler denser charge headed into the combustion cycle.


 Q. Why do you recommend we wipe the top of the I-M Shield before using Weld Tape on the top of it?

A. The foil on the Sticky Shield has a coating for manufacturing purposes and during installation grease and dirt can also affect the Weld tapes bonding capability. Wiping with a pre-paint cleaner ensures it is sticking to a clean surface.
