Good plug
This plug fits 66cc Chinese built 2 stroke bicycle motors. It is a hot plug rated 4 so it would be best in cold climates. Still better than the stock plug and more affordable than the bh series NGK, Good plug for the price. I pulled it after a few miles and it is burning nice and brown, the stock plug was covered in unburned fuel and coated in oil, not with this one. It got pretty hot but I am in Northern AZ its been 95 outside at 3300 feet above sea level, so its not the optimal plug for me. If you live in the Northwest like OH, or PA this would be a great option.

GOOD SPARK !!!!
THESE NGK B-4L PLUGS ARE A LITTLE HOTTER THAN STOCK MAKES A BIG DIFFERENCE ESPCIALLY ON OLDER ENGINES LIKE MY "68" YEAR OLD MERCURY FLATHEAD ENGINE

Perfect fit for my bicycle engine
Loved this plug for my 2 stroke bicycle motor. I like that it is NGK and it is a hotter plug for the winter time.

It Works
This is the only place I could find these spark plugs which my husband needed for his motorized bicycle. He is very satisfied with this product.
