Lower Temps. Higher Density. More Power.
Gain cheap horsepower by lowering intake air temperatures—simple, affordable upgrades like intake manifold shields boost power without major mods.
<li>Compatible with OEM and aftermarket intake manifolds
The I-M Shield intake manifold heat shield is an affordable way to boost horsepower by reducing air intake temperatures. Designed to block heat transfer from the engine to the intake manifold, it creates a denser air/fuel mixture for increased power on naturally aspirated, turbocharged, and supercharged engines. Ideal for V-series and boxer engines, it supports the manifold air density theory—cooler intake temps mean more performance. Easy to install with high-temp adhesive, the I-M Shield fits clean, semi-smooth surfaces and is available in pre-cut or universal kits. Whether you’re a professional engine builder or DIY mechanic, it’s one of the best dollar-per-horsepower upgrades for gas or diesel engines.
Yes, you do need to remove any factory foam underneath the intake manifold. The I-M Shield must stick to a hard surface 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.
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.
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.
There are so many ways to make horsepower, the answer is literally unlimited. The one theory a
ll experts can agree on is lowering your intake air temperatures. People run their fuel through fuel coolers, heck in the old days they used to put ice on the intake manifolds. High performance superchargers and turbo’s all come with inter-coolers. Think of the intake manifold heat shield as that, and inter-cooler for your intake. The I-M Shield is the next technological step in lower intake temperatures and answers that age old question, how do I make cheap horsepower.
