I put it in a Sym Citycom. The only thing I noticed is that it starts in the morning with half the kick. It's worth it!

There is nothing better than this spark plug; it’s worth the money. The starter and battery are free from wear and tear, and when it was cold, I was anxious about whether it would start immediately. This spark plug plays a crucial role; it changed the dynamics of the vehicle, a tick in the starter and smiles!!!!
