Not Walbro or OEM on anything. They are unbranded generic garbage that I would never trust in my saw that don't even look like the Walbro filters they are trying to pass them off as. Might as well have just bought some fake filters off Amazon. Even small companies in Wisconsin are joining the dishonest merchants on Amazon and sending you whatever **** they have that doesn't even resemble what they claim they are selling. Total waste of time and money. If you want real Walbro fuel filters, don't buy these. We'll see how long it takes them to yank this review considering how honest they are.
