Is anyone currently running a TECH filter on anything they have or seen them available? I was running filter searches on amazon/ebay etc. and I found they sell them in cases of 12 for not a bad price and I would be interested to try them out. Either looking for pics here or I might buy a few and run 2 and cut open a new one to see what the media is like and then cut the used ones open later. I have seen some purolators cut open lately and seems they might be improving or at least tightening the pleats together etc. I'm gonna try to get away from the Motorcrafts 820s because they have been problematic for awhile. I have some pro-selects etc right now but I'd like to get away from the combo valve. I know there is a napa filter sale coming up soon so I will look into that as well. Just nice to have options. I'm always looking for different filter options.
