And it's not too flow restrictive, as shown by info from Motorking. Besides, a positive displacement oil pump can only cut oil flow to the engine when it's in pressure relief. Now if the filter was ran 18K miles on a pretty dirty engine then it could become flow restrictive from debris loading.
Did all these bad running engine symptoms show up the day the Ultra was installed? Or was it after many thousands of miles?
Here's a closer pic. It doesn't look like it's full. I'll try and take it apart later.
The symptoms we're from the beginning. I have another filter on for around 2000 miles and it's still fine.
