K&N's Stubstack is designed to reduce turbulence and increase airflow into your carburetor. Available for Edelbrock carburetors, the unit fits inside the air cleaner housing and slides snugly over the choke horn. Test results have shown up to 40 CFM increase in airflow, which can translate into a 10% horsepower gain just by using the Stubstack. Pick one up today and increase your cars power and performance.
