This was very helpful, as it is evidence that Fram has cheapened their Ultra air filters.
I will be looking for a replacement for Fram Air filters.
What is the general consensus opinion on Super Tech Air filters?
Also, I like Pentius oil filters. I saw their air filters for sale on Amazon. Has anyone tried a Pentius air filter and is it high quality?
Based on everything known at this point, which air filter is very well made, and has a high efficiency near 99% @ > 20 microns
