Here are a few links that will compare the different oil filters and their differences. I prefer the HD filters, they were specked for the particular engines from the start with the proper micron rating, bypass spring pressure and are well constructed. I have cut my filters open to diagnose a potential problem at oil change time and can tell you the HD filters are very well constructed compared to others.

This first link is a very informative link but you have to copy and paste it to get it to work properly.You can select the different filters on the left of the page.


If this first link doesn't work correct here, copy and paste it into your browser. Click the brand links on the left of the page.
