The Edelbrock 1-inch cloverleaf carburetor spacer is an open aluminum spacer used with 4500-series cloverleaf manifolds to add plenum volume and increase carb-to-plenum floor distance. At one inch thick, it provides heat insulation benefits and helps change the intake tract geometry for tunability. This spacer is intended for use where added distance or plenum volume is desired.
