HPS 3-1/2" - 4", Silicone Straight Reducer Coupler Hose, High Temp 4-ply Reinforced, 89mm - 102mm

The coupling was just what I needed to make a better connection between my MAF and the CAI that I was running. The coupling that came with the CAI was hard and dried out after years of service. Then HPS fit perfectly and looks better than the original one.

Fits great and well made.

Fitment was perfect on both ends! Look awesome on my throttle body!!
