Description
A quality carburetor spacer does more than fill a gap—it optimizes fuel atomization, improves heat management, and can deliver measurable gains in throttle response and mid-range torque. The Moroso Phenolic 1/2in 4 Hole spacer is engineered from phenolic material, which provides superior insulation compared to aluminum, keeping incoming charge temperatures lower and allowing your engine to produce denser, more combustible air-fuel mixture. Whether you’re tuning a street engine or dialing in a dedicated race platform, this bolt-on spacer is a proven foundation for carburetor optimization.
