Mileage is 40k. Don't worry though, it took a quick bath in a parts washer the other day though and it's good as new
Like I said great option if you want a port & polished manifold or some powdercoat like I did. Send this one off, and have no down time with the Jeep. Once it's done take your own time, pick a day to do install, and boom after two hours it's on. Then sell your OEM just as I am!
