Overtake Phenolic Intake Manifold Thermal Spacer | Reduce Heat, Increase Power

Is your Subaru engine running at its full potential? One of the biggest obstacles to maximizing your engine's performance is heat soak – when heat from your engine transfers into your intake manifold, reducing air density and limiting power. The cooler the intake air, the more horsepower your engine can achieve. That's where the Overtake Phenolic Intake Manifold Thermal Spacer comes in, providing the perfect solution to this long-standing issue by raising the intake manifold off the superheated boxer engine.

What Are Phenolic Spacers?

Phenolic spacers are widely used in high-performance automotive applications, but this technology is a breakthrough for Subaru owners. By reducing the heat transfer between the engine and intake manifold, Overtake Phenolic Spacers help lower intake temperatures and increase power.

How Do Phenolic Spacers Work?

Your Subaru’s intake air travels from the airbox into the turbo and then into the intake manifold. As it passes through the manifold, it absorbs heat from the surrounding aluminum, which decreases air density and robs your engine of potential power. In stock form, a steel gasket sits between the intake manifold and engine, allowing heat to transfer into the manifold. Replacing the steel gasket with the Overtake Phenolic Spacer greatly reduces this heat transfer.

Upgrade your Subaru’s performance with the Overtake Phenolic Intake Manifold Thermal Spacer and experience cooler intake temperatures, better air density, and more power.
