Same in that they are not metal, but a different material and technology. STP and SuperTech are mostly made from the Champion Labs "Ecore" product line and are probably identical filters. Ecore uses a plastic center tube, fuzzy media end caps and a one piece bypass/anti-drain back valve. It appears to be a product which was engineered primarily to reduce manufacturing costs and consolidate part numbers as much as possible. Whether or not Champ also managed to produce a top quality filter at rock bottom costs is open to question.
