Includes all 3 heater hoses (inlet and outlet and the small one that goes from the heater valve to the heater box) and clamps you need. These hoses must be replaced every 4 years or every 50,000 miles. This set is for 2002tiis and Turbos. 2002 base models have different hose variations depending on the year of production. One of the hoses has been discontinued by BMW but has been replaced with a high-quality  reproduction made in Germany.
