K.E.D Billet Coolant Expansion Hose Fitting (E46 M3)
Koflach Engine Developments billet aluminium coolant expansion hose fitting for E46 M3.
Thanks to heat and the stiff type of plastic used by BMW for the expansion hose on E46 M3 – which runs from the top radiator hose to the top of the expansion tank – it becomes brittle over time and is easily broken.
To solve this, KED developed a billet fitting for the upper radiator hose that then allows a 8mm I/D flexible silicone hose to be used.
This listing is for the hose fitting only – full kit with hose and clamps coming soon.
