Someone in the parts section has an 85 cali aircleaner for sale right now--They are like mini Semi truck filters and are the best---but the elements are around $51.00
Some people could modify a 76 w115 300d aircleaner -add another aperture -and enlarge the outlet to turbo elbow tube and also have a good aircleaner that route too, Those elements are about 3/4 the surface area of the 85 Ca one and much less expensive.
