The Moroso 4500 open-plenum carburetor spacer is a 1/2-inch wood spacer that installs beneath a 4500-style carburetor and above the intake manifold. Its open plenum design and half-inch thickness provide measured separation for clearance and intake layout considerations. The wood construction offers an alternative material choice for traditional spacer applications without altering flange patterns.
