In Fastlane your right OEQ stands for "original equipment quality" Another words this is a company who makes original equipment parts say for another car besides Toyota lets say. Maybe they are the OE supplier for that same type of part but for Honda instead of Toyota. Still it is a very high quality part. OES "original equipment supplier" for short it means "Dealer Item" Some parts are only avalible from the dealer. If you give me the part number that pops up in the shopping cart when you hit buy I will tell you exactly who is the manufacture for the part you have in question. Hope this answers your question
