This Steeda exclusive I-M Shield significantly reduces the amount of heat transfer from the top of your 5.0L Coyote powerhouse equipped with a 2018 and newer OE 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. 

No worries about peeling or adhesive issues. The 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.

Great fitment and a precise cut. I-M Shield is pre-cut for the OE 2018 intake manifold (162 JR3Z-9424-A). This makes installation a breeze and ensures that you are getting proper heat-shielding for your intake manifold. Think of I-M Shield as an intercooler for your 2018+ Coyote intake manifold, reducing the temperature of the air/fuel inlet charge for higher density and more power.

2018 manifold heat shield
Easy to put on. I would recommend making a template first.

Keeps IATs Down
Bought this with the 2018 intake manifold for the Mustang GT. This has made a significant difference in lowering the IATs. IATs stay 5 - 10 degrees above thee ambient air temperature. The price is high for the material it's made of and the only reason it got 4 stars.

Overlooked easy modification
Used in conjunction with Steeda CAI and tune. Easy to install and helps take full advantage of a CAI by helping air stay cool all the way into the cylinder heads
