Description

If you’re running a Holley 4150 or 4160 carburetor, airflow consistency directly impacts throttle response and fuel atomization across the rpm range. The Stub Stack 85-0200 air flow director mounts directly to your carb’s fuel bowl, smoothing incoming air charge to reduce turbulence and dead spots. This polyurethane construction resists fuel degradation while delivering the precision intake tuning that separates dialed-in carburetors from stock setups.
