Below is a picture of the air intake for the Broil King 5000. As the tape measure shows the flat surface area located around the daisy-wheel air intake is not large enough to accommodate the 5-1/2" O.D. and 5-1/4" I.D dimensions of our metal manifold. However, if you were able to use temperature resistant adhesive tape such as silver duct tape to close the gaps where the metal manifold overhangs the flat area on the BK 5000 air intake panel, our Universal Blower Assembly should be able to be used.
There are no immediate plans to develop an adapter specifically for the BK 5000.
