Thermostat Heater Bypass Hose T-Connector, BMW - E30 318i/325e/325i/M3

This part is listed by BMW as BMW part number 64118367832 (64 11 8 367 832) and is described as the T-connector used by the drain/bypass hose that runs from the heater thermostat to the main heater return hose. This may be found on all E30 318i, 318is, 325e, 325es, 325i, 325is, 325iX, and M3 if BMW or the dealer installed the heater core thermostat on your car. Since this was a retrofit from BMW the main return hose (11531722743 or 11531289377) must be cut for the T-connector to be installed.

This is a Genuine BMW E30 hose T-connector 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.
