Intake Manifold Spacer by BBK Performance®. Phenolic manifold spacers have also become a popular way of increasing manifold to valve cover clearance to accomodate popular bolt-ons such as performance rocker arms and rocker arm covers.
- Increases intake manifold runner length and reduces heat transfer from the lower to the upper intake manifold
- Increased runner length and reduced air inlet temperature results in 4-7 horsepower increase
- Also increases manifold to valve cover clearance, enabling the installation of aftermarket valve covers and rocker arms
- Easily installs between upper and lower intake manifold
- CNC machined from a custom phenolic fiber material
- Comes with new bolts and gaskets
- Includes detailed installation instructions
- Limited 1-year warranty
- Proudly made in the USA
Usually getting more power from your engine requires a lot of time, sweat, and cash, but this phenolic intake manifold spacer has proven to be an easy, affordable, bolt-on path to increased performance. Easily installed between the upper and lower intake manifold, this spacer increases power 2 ways: First, adding the spacer effectively lengthens the intake manifold runners, which helps maintain air velocity and creates a "ram air" effect into the intake ports. Second, the spacer dramatically reduces the heat transfer from the lower to the upper intake manifold, which in turn reduces the inlet air temperature. Cooler air is denser and contains more oxygen and more oxygen in your engine's air intake charge means better combustion, resulting in greater engine output.
CNC machined from a custom phenolic fiber material, this spacer comes ready to install with new bolts and gaskets, with detailed instructions to guide you through the easy installation. As an additional benefit, the increased height of the upper intake manifold with the spacer installed allows the installation of aftermarket valve covers and rocker arms.
