As most of you know, Champion Labs has manufactured several big name decent quality filters such as Mobil-1, K&N, Bosch, Luberfiner, etc. They also make the economy STP filter. I haven't inspected an STP filter, but if it is as decent as the Supertech, that might be the next route to economy filters. The few quick reviews I read showed it to be similar to other Champion made filters, but YMMV as these are usually larger automotive filters that get dissected. Now that Supertech is gone, I'll probably just buy whatever I can get locally, which would be Wix/NAPA.
