This is especially important for GY6 GY6 models because similar model names can use different parts by year or trim.

Recheck listed specs such as Thread Diameter: 10mm (0.39"), Thread Length: 12.7mm (0.5"), 10mm. If any connector, mounting point, size, or year detail is different, confirm fitment before installation.
For the same price, I could only buy one at auto stores. I don't need 4, but why not!? What a steal! They work absolutely great. I used one now for months and it is still like new. 3 more put aside just in case. I'm sure I won't need all of them the entire time I own this moped.
