The aFe Magnum FORCE straight bellow reducing coupler is an injection-molded high-temp silicone sleeve that joins 3" to 3-1/8" tubes across a 4-3/4" length. Its bellow profile allows for flexibility and movement while stainless-steel worm-gear #048 clamps provide secure, corrosion-resistant connections in industrial, truck and off-road intake setups. This part is intended for non-pressurized intake use.
