aFe Magnum FORCE Intake Coupling Kit (4-3/8 IN ID to 3-7/8 IN x 30 Deg.) Elbow Coupler - Black

This coupling features a 30° angle and is designed to connect to tubes with a 3-7/8” and 4-3/8” diameter. It’s commonly used on aFe POWER cold air intake systems, but can be used for a variety of projects. Its silicone construction features a layer of polyester reinforcement, making it extremely durable and less prone to deformation, tearing, and other damage, than average couplings. Two corrosion-resistant stainless-steel worm clamps are included, providing a secure seal for virtually any application.
