The aFe POWER universal silicone coupling connects a 3.5-inch ID end to a 3.25-inch ID end over a 3-inch length for intake or intercooler plumbing. Made from 100% silicone with three layers of polyester reinforcement and a 4mm wall thickness, it resists deformation and helps maintain a consistent seal. Two corrosion-resistant stainless steel clamps are included to secure the coupling in common plumbing setups.
