Replaced my MAFs as part of the 100K maintenance, but these still operated fine when I took them out. They might have been replaced before now, because these certainly don't look like they've accrued 100K miles.
They look nice and clean. See for yourself, I can post a high res pic if you'd like. Either way, have a set of as-is spares for a tenth the price of what they cost new! $100 shipped to the CONUS, overseas can be worked out for additional.
