The reason I used Super Tech filters initially is that they used the same media as Luberfiner HE filters. HE= High Efficiency. That and some of the Champ engineers were using it on their own cars.
STP has a better yet media.
Mobil 1 has the premium media.
Now can you tell me from the other brands you have with more sq inches of media how "good" their efficiencies are compared to Super Tech, STP, and Mobil 1?
My personal opinion is that unless you look at the premium filter in another brands line, the Super Tech has higher efficiency media. And that includes Wix, Purolator, Fram, Baldwin, Fleetguard, Donaldson, Mann, Mahle, etc.. [/QB]
