You’re looking at a genuine Porsche coolant reservoir breather hose, OEM part number 98710628701—a used line pulled from a donor Boxster or Cayman. Also called the breather hose or line for the coolant expansion tank, this rubber hose handles pressure equalization in the cooling system as the engine heats up. On the M96/M97 flat-six engines (2.7L, 2.9L, 3.4L variants), a cracked or brittle hose can introduce air into the coolant loop, leading to low coolant warnings or erratic temperature readings. Inspect the rubber for hardening or splits before installation.
