Auto Transmission Heat Exchanger Hose, BMW - F3X 335i/435i Base (not M Sport)

This part is listed by BMW as BMW part number 17127600551 (17 12 7 600 551) and is described as the hose from the radiator to the auto transmission oil cooler (heat exchanger) on F30 335i, F32 435i, and F34 335i GT without the P337 M Sport package.

This hose is for base model 335i/435i where the hose connects from the main radiator to the heat exchanger. The M Sport models have a separate radiator for oil cooling and the heat exchanger is not directly connected to the main radiator.

This is a Genuine BMW oil cooler 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.
