K&N Stubstacks

3.45 out of 5 stars 11 Customer Reviews

K&N Stubstacks reduce turbulence, improve metering accuracy, and straighten and increase the airflow by reducing restrictions. Hot Rod magazine's flowbench testing recorded an airflow increase of 28 cfm on a 650 cfm carb, and 40 cfm on an 850. This extra airflow builds up to 10 percent more horses. They fit standard bore Holley carbs, and work best with 4 in. or 5 in. tall elements.
