Yesterday when I went to walmart I took a peek inside 3 filters (some for some applications I was curious about) and the filter media was different for one of them. That site doesn't have a picture of the Super Tech filter, so I'm not sure which media it is and I forgot to check that filter yesterday.
If you also notice, the two wix filters that were tested don't have the identicle ratings either.
of course, K&N, M1, A/C, and Supertech all have similar looking media... why would champion use a different media on the STP?
Then again, look at the k&n and the Supertech. If there is a small amount of error in the test, those two medias coudl be the same.
