Change your spark plug at least every 2,500 kilometers and always install one from NGK so your scooter will always run like clockwork. This is the same spark plug that Piaggo/Vespa mounts as standard.

This is the spark plug for Vespa and Piaggio scooters with the iGet engine.

To be sure, check the list below to see if this spark plug fits your scooter (note the first 5 digits/letters of your Vehicle Identification Number found on your registration certificate)
