I have looked online but could not find any info or comparisons of the Fram HP series oil filters vs anything else. I had a couple laying around and decided to do one myself.
Couple things: The fram has a bypass valve rated at 22 psi. I prefer no bypass on a high dollar performance engine. A bypass is important on a daily driver. When you are pushing it, you want to filter ALL your oil.
The k&n does have a anti drain back valve, higher burst pressure, and lower micron rating.
