Huckstorf Diesel’s AFE 03-04 6.0L Intake Manifold improves torque and increases your truck’s horsepower. This high turbulent manifold will enhance your turbo spool-up and improve your throttle response. The 6.0L Intake Manifold will lower exhaust and gas temperatures allowing for a decrease in fuel usage. This is the perfect turbo upgrade. A superior internal cross section with turning vanes increases intake air flow vs. stock intake manifold. The backside is pre-tapped for easy and clean gauge installation. Huckstorf Diesel’s intake manifold represents the next generation of intake manifold design. The intake manifold uses a unique MDV (Multiple Directional Vane) technology to guide the air through the manifold, maximizing air flow. Stock intake manifolds have sharp bends and corners allowing for consistent air flowage where typical dead air zones are created. These dead air zones choke down the air and restrict airflow to your engine. The Multiple Directional Vane technology uses smooth bends and directional vanes to form multiple air paths through the manifold. This premium manifold is one of Huckstorf Diesel’s many top-of-the-line quality diesel exhaust parts and systems.
