The aFe Magnum FORCE bellow-style coupler is an injection-molded high-temperature silicone component with a 3-7/8" ID bellow profile designed to interface with a 3" OD tube. It uses stainless-steel worm-gear #056 and #064 clamps for durable, corrosion-resistant connections and allows for expansion, movement and vibration in intake assemblies. Intended for non-pressurized intake use; avoid pressurized or forced-induction applications.
