The aFe Magnum FORCE 3-1/4 in ID x 4-1/2 in bellow coupler is a flexible silicone connector designed for 3-1/8" tubes, featuring multiple port holes for PCV or vacuum connections. Its bellows design eases installation where alignment varies and allows expansion, movement and vibration between hard pipes. Two corrosion-resistant stainless steel clamps (#052) are included.
