This part is listed by BMW as BMW part number 17128096446 (17 12 8 096 446) and is described as the hose running from the charge air cooler radiator to the charge air cooler's water pump on the S58 engine in the G80 M3 and G82 M4. The top-mount intake air cooler has its own cooling circuit including a radiator mounted in front of the main radiator. This hose supplies cool liquid to the aux water pump for the top-mount cooler.

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. The plastic clips and metal retaining clamps on hoses are stronger than before but they are only really good for one-time use. Once removed they never seem to seal as well, leading to a leak soon after. A new hose is recommended any time the old one is disconnected (unless it's only a couple of years old). We highly recommend that you replace your radiator hoses as a preventative measure before they fail in order to save you from further headaches and expenses.

This is a Genuine BMW S58 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.
