4-1/2” to 4” Reducer:
This 3-1/4” long coupling is designed to connect to tubes with a 4-1/2” and 4” diameter. It’s commonly used on aFe POWER cold air intake systems, but can be used for a variety of projects.

Flexible Bellows Silicone:           
Its bellows design is extremely flexible, making it easy to install, even when dealing with misaligned tubes. It allows for ample expansion, movement and vibration in-between two hard pipes.

Stainless Steel Clamps:
Two corrosion-resistant stainless-steel worm clamps (#064 & #072) are included, providing a secure seal for virtually any application.
