I have verified that the Zongshen 200GY-2 oil filter is an exact replica of the Yamaha TW200 oil filter. Located below is a photograph of the two oil filters, shown side by side. The Zongshen filter is on the left, and the Yamaha filter is on the right.
Here is a photo of the Yamaha filter and its package.
In my opinion, the Yamaha oil filter is superior in quality to the Zongshen oil filter. Therefore, I will insert the Yamaha filter during my next oil change.
