Moroso 64943 is made from an advanced phenolic compound that is specially formulated to reduce heat conductivity ten times greater than aluminum. Moroso 64943 reduces fuel temperature inside the carburetor which results in a denser, more powerful fuel charge to the manifold. Moroso 64943 comes pre-drilled for alignment pins.
