CQ was Affinia made years ago (old Wix parent company), then they were made by Fram/Champion (when they were working together), now they're Purolator/Mann & Hummel (who owns Wix now, so it's almost like a full circle). The CQ reds now look a lot like a Purolator Classic, the blue ones look like a Purolator Pure One. There is also a CQ "heavy duty" filter which is identical to & made by Baldwin, I have one for the Express 6.0 in my sig, but it's not installed yet, along with a few Baldwin reds, they all look alike except for paint.
