Description

This cooling system hose routes coolant from the water pipe to the throttle body (bypass path), ensuring consistent temperature control and proper operation of your engine’s cooling system. It’s a direct replacement for BMW part 13541703945.

This hose matches BMW’s original dimensions, quality material, and fitment standards. Its construction ensures long-term durability and resistance to heat and chemical wear.

A failed bypass hose can lead to overheating, inconsistent engine warm-up, or cooling system pressure issues.
