The aFe Magnum FORCE straight reducing coupler (3 in ID to 2-1/2 in ID, 3 in long) is a silicone connector intended for joining those tube sizes and serving as a spare on aFe cold air intake systems. Its reinforced silicone construction provides durability and flexibility, while included stainless steel clamps secure the connection and resist corrosion. Use is limited to non-pressurized sides; it allows for movement and vibration between pipes.
