The Harley-Davidson part number 26995-86 (including its updated iterations 26995-86A and 26995-86B) is an intake manifold-to-head seal used to create an airtight compression barrier between the engine cylinder heads and the carburetor or throttle body manifold. These seals are critical for preventing vacuum leaks, which can cause lean fueling conditions and erratic engine performance
