aFe Magnum FORCE Intake Coupling Kit (4-3/8 IN ID to 3-3/4 IN ID 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 two layers of polyester reinforcement, making it extremely durable and less prone to deformation, tearing, and other damage, than average couplings. The built-in port hole (5/8″ ID x 1/2″ H) allows for easy connection to a PCV line. Two corrosion-resistant stainless-steel worm clamps (#064 & #072) are included, providing a secure seal for virtually any application.
