Spark Plug - NGK - C7HSA - for 50cc to 153cc Horizontal Engines

This spark plug fits 50cc, 70cc, 90,, 110cc, 125cc, 140cc, and 153cc horizontal engines that are based on the older Honda engine. If you have a dirt bike or small ATV with this type of engine this is likely the spark plug you need. We also carry this spark plug in a generic Chinese brand that works just as well (in our opinion) and for less money. Some super pocket bikes also use these plugs.
