Expansion Tank Connecting Hose, Rogue - E46 M3

The original vent line uses hard plastic fittings that are prone to cracking and leaking coolant. Rogue's solution to this common problem is CNC 6061 aluminum fitting and 45° brass elbow that will never crack. The fitting is paired with a heavy-duty 200psi rubber hose and OEM-type crimp clamp.

This is a 1:1 swap with your original coolant hose and includes all hardware needed for install.
