It's actually more expensive than the factory BMW one. Are you near a BMW dealer or have access to one?
Don't believe the rumors that "it's the same as any aircooled VW" that's not true except for the 70-73 /5 bikes.
Sorry don't recall the part number from NAPA but I believe it was from an 80s model BMW car.
