Upper Radiator Hose - E46 M3 Coupe and Convertible

This Upper Radiator Hose is a stock replacement for your E46 M3. Rubber hoses are ideal when new, as they allow some movement and flexibility during driving. The only problem is that they begin to degrade as they age, and can eventually fail, leaving you with the potential for loss of control from coolant spilling and/or an overheating situation.

Replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

NOTE: E46 and newer Z3 hoses include plastic ends
