aFe Power Magnum FORCE 3-3/4in ID To 3-1/2in ID x 15 Deg Replacement Coupling Kit

This coupling features a 15° angle and is designed to connect to tubes with a 3-1/2” and 3-3/4” 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. The built-in port hole (1/8" ID x 1/2" H) allows for easy connection to a PCV line. Two corrosion-resistant stainless-steel worm clamps (#056 & #060) are included, providing a secure seal for virtually any application.
