Josh,
Seller has just (1) feedback! There's your problem.
Someone offered him bigger $$ for the intake, so he's
going to turn you away. If you follow the links through
eBay, you can report the problem fairly easily. Don't
let this knuckle-head get away with this!
BTW, I didn't see anything on the auction where he notified
you, or anyone else that the item was already sold elsewhere.
