Review on High Performance K&N Motorcycle Oil Filter KN-153 for Synthetic or Conventional Oils - Designed for Ducati Motorcycles (Black) by Brent Porter

I used the KN-153 the last few times I changed the Ducati oil and filter. Although this time the correct part number is stamped on the side, the internal geometry is different and the threads are countersunk much deeper. There will be no threads on my bike. Aside from the obvious difference when looking at the open end of the filter, this bad new filter is labeled 'Made in Thailand'. I called K&N and they admitted they switched manufacturers and gotten bad mileage with those filters. They replace mine but it's still a burden as I can't ride yet. There is further discussion on several forums including this one: [.] Supposedly K&N removed all Thai filters but apparently didn't install all of them. Beware.
