The Spectre 3-inch velocity stack adapter allows you to mount a larger six-inch inside-diameter cone air filter to a smaller intake tube. Available neck sizes match 2.5-inch to 4.5-inch tubes while the smooth, funnel-shaped inlet reduces restriction and turbulence for cleaner airflow. Durable construction is intended for lasting use; couplers and hose clamps are not included and must be sourced separately.
