Heat soaking through the intake manifold raises air intake temperatures, reducing density and robbing the 7.3L Godzilla of the power it should make on every pull. Heatshield Products' I-M Shield blocks that heat transfer at the source, giving the 2020-2026 F-250 and F-350 a denser air-fuel charge without touching the tune or swapping major components.
Cooler charge temps, measurable power gains. By blocking conductive heat from migrating into the intake manifold, the I-M Shield increases air charge density before it ever reaches the combustion chamber. Denser air means a more complete burn, which translates directly to more power on naturally aspirated engines like the Godzilla V8.
Rated for serious under-hood temperatures. The I-M Shield carries a continuous rating of 1,100°F and an intermittent rating of 2,000°F, so it handles the sustained thermal environment of a hard-working Super Duty without degrading or losing performance over time.
Fits OEM and aftermarket manifolds. Pre-cut for the 7.3L Godzilla platform, the shield attaches to clean, semi-smooth manifold surfaces using high-temp adhesive. No drilling, no brackets, and no permanent modification to existing hardware. Aftermarket intake manifold swaps are also covered.
Product Benefits
- Heat Blocking Performance: Stops conductive heat transfer from the engine into the intake manifold for a cooler, denser air charge.
- High-Temp Rated: Continuous rating of 1,100°F and intermittent rating of 2,000°F for sustained use.
- Pre-Cut Fitment: Shaped specifically for the 2020-2026 7.3L Godzilla F-250 and F-350 Super Duty.
