Rubber hoses are ideal when new, as they allow some movement and flexibility. But they begin to degrade as they age and can eventually fail. A new hose is recommended any time the old one is disconnected (unless it's less than a year old). We highly recommend that you replace your cooling system hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

This is a Genuine BMW M550i cooling hose with a two year warranty. Buying a Genuine part will usually be more expensive than an OEM or aftermarket brand but you are assured that it meets BMW's designs for fitment, performance, and longevity. It will also be the very latest design, incorporating any updates or revisions that an aftermarket brand typically will ignore.
