Product review (1 stars): Don't buy this, it is going to disappoint you: Poorly designed and manufactured and doesn't even fit together
This must be a cheap reproduction of an OEM kit, hence it is less expensive. The manufacturer couldn't be bothered to swage the end of the duct leaving the hapless tech with the task of crimping the end manually. Additionally, the ends that do fit together are sloppy AND in the wrong direction so they create a step in the flow direction for nice loss in flow efficiency to boot! Great job to "Whoever Industries" that made this thing, your engineering, quality control, and manufacturing have created a piece of poorly executed crap.
