If you're at all handy you can make one yourself. I made a prototype out of stiff cardboard and then had a sheet metal shop build it for me out of aluminum. I used the BMW rubber seal that runs along the firewall to seal the top edge against the hood. That part provides enough material for two shields. It was very simple to do, looks great and gives you the satisfaction of engineering something yourself.By the way, I don't have the data to back it up, but it definitely seems to work.The aluminum stays cool to the touch and blocks off the entire area around the filter. The K&N intake noise is greatly reduced.Total cost for the shield was around $55.
BMP Design sells a small shield that just covers the radiator side of the filter.If you're interested in making one I could probably give you some dimensions to get you started.
