BBK 1/2" Phenolic Spacer for Edelbrock 1986-1993 5.0L Intake Manifolds.
As one of the most affordable bolt-ons for today?s automotive enthusiasts, BBK?s phenolic manifold spacer kits have proven to be a great way to increase performance. CNC machinedfrom a custom phenolic fiber material, these spacer kits increase power by dramatically reducing the transfer of heat from the lower to upper intake manifold. This in-turn produces lower inlet air temperatures which results in added horsepower and the ablity to add more timing advance with less detonation.
BBK phenolic manifold spacers have also become a popular way of increasing manifold to valve cover clearance to accommodate popular bolt-ons such as performance rocker arm covers.
