- Although similar looking, AVS (Air Valve Secondary) throttle blades differ slightly from standard 4bbl carbs, which will result in butterfly interference and dangerous stuck throttle. This spacer solves this issue with matching sized ports.
- This spacer has staggered bore size diameters that clear the butterflies on AVS carbs. Now, AVS owners can benefit from the same Torque-Flow plenum design standard 4bbl carb owners have enjoyed for years.
