I believe they came on the 5000 but not quite sure. There a frount mount design and have both inlet and outlet tubes at one end. It's measurements are something like 19"x7"x4". There's always a couple on ebay and wondering if anyone ever used one or are using one right now, and fitment wise how it went?
