There was one that came with the car but it has never been reproduced. This is shown in the two pictures. The 90 degree bend was originally an aluminum piece later changed to sheet metal as shown in the photo. You are going to have to look for it. There was also an oil bath air filter for dusty areas that bolted to the head. This is shown in the third photo. The duct down to the mouth of the carburetor is not shown in the picture.

Followup: I guess I need to slow down and read every word carefully. I could have sworn it said air filter.
