Spectre Velocity Stack Adapters

Spectre Air Filter Inlet Adapters and Velocity Stack Inlets are designed to allow you to attach a larger 6 inch diameter flange air filter onto a smaller diameter air intake tube. Available with many different neck sizes to match 2.5 inch to 4.5 inch tubes. In addition, Spectre velocity stacks also have a smooth funnel shaped inlet that will reduce restriction and turbulence of incoming air.
