WAI 17781N Starter

Starter for Volkswagen Applications

The WAI 17781N starter is a new 12-volt starter built for Volkswagen vehicles that need reliable cranking performance and OE-style fitment. It uses a permanent magnet gear reduction design with a 1.1 kW power rating, 9-tooth drive, counterclockwise rotation, and flange mounting.
