I found the MAF sensor on eBay for $22.99 just yesterday, it’s on the way now. Local parts stores wanted ~$96 for that.

sometime stuff on eBay is not limited to location so they can be somewhere with low rent in the middle of nowhere, or they can be high up in the distribution chain so stuff is cheaper, or it could be fake part. You haven’t tell me what kind of brand you’re getting so i won’t talk about your local part store.

That came out of a U-Pull-It junkyard

Junkyard is like a warehouse without roof, and since you’re doing work pulling out the stuff yourself, i’m not sure why you’re wondering it’s cheap.
