afe Magnum FORCE Intake Coupling Kit (4-1/4 IN ID to 3-3/4 IN ID x 2-1/4 IN L) Black Straight Coupler - Universal
4-3/16 IN to 3-3/4 IN Reducer:
This 2-3/8 IN long coupling is designed to connect to tubes with a 4-3/16 IN and 3-3/4 IN diameter. It's commonly used on aFe POWER cold air intake systems, but can be used for a variety of projects.
Silicone Construction:
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.
