Two internal design styles of spacers are available. The open plenum design increases plenum volume for improved higher rpm results. The external surface is 3D machined to match the internal shape to ensure the best lightweight design while still retaining strength. The Carburettor is a lightweight CNC machined billet aluminium carburetor spacer / adapter that has been proven by engine dyno testing.
