As one of the most affordable bolt-ons for today’s automotive enthusiasts, Phenolic Manifold Spacer Kits have proven to be a great way to increase performance. CNC machined from a custom phenolic fiber material, these spacer kits increase power by dramatically reducing the transfer of heat from lower to upper intake manifold.
