Price keeps going up, but at least the quality is still there
I've been buying Bosch and NGK spark plugs for a couple of decades now. I don't know why they cost so much now, compared to what they cost in the 80s, but at least they're still the same quality. They used to be a buck apiece.I use these in my 2003 Honda Silver Wing scooter. It will work in all years, at least up until 2013, as the engine hasn't changed.

Great quality spark plug
I've installed this spark plug in a Honda Metropolitan 50cc scooter and have ridden over 6 thousand miles on it already and it continues to perform very well. This is an original replacement for the OEM plugs and the original looked quiet good when I replaced it at 5000 miles. The electrode was not substantially worn and there was no excessive deposits on the plug. I will definitely buy another one like this when it's time to replace it again. The plug I ordered from Amazon is manufactured in Japan, so it's another cool thing to consider.

Was happy to find since it's for an old vehicle
This was exactly as described and received quickly. I was very happy to have found them as it goes into an older, limited production motorcycle.
