BBK Performance Parts Phenolic Intake Manifold Spacers are an affordable and easy way to add additional horsepower. These spacers are CNC-machined from a phenolic fiber material that drastically reduces heat transfer from the lower plenum to upper plenum of the intake manifold. This inturn produces lower inlet air temperatures for increased power. In addition, phenolic spacers provide additional clearance for taller valve covers.
