K&N makes flat conical filter assemblies and media for the SU setup that 
will clear the 80 booster. The media is cotton gause bound to a wire mesh 
which is oiled to trap dirt. They are very good at letting the air through 
without restriction and the filters can be cleaned and reused. Some people 
have concernes that it doesn't get all of the dirt. It probably doesn't but 
it gives you a little more HP. Unlike paper, they work when exposed to rain. 
You should reset the mixture on your carb if you switch. I use one on my 
weber DGV and I am very pleased. Moss, Victoria, Seven Enterprises, and 
Pierce Manifolds carry them

I have been running my 1980 'B with a pair of HS4s for about two
years.  I used the pre-1974 exhaust and intake manifolds and
a pair of flat air filters (about 1-1.5 inches thick) with the
holes for the carbs off center so that they clear the power
brake booster.  These filters use a supposedly washable foam as
a filter medium, which I am not happy with.

Has anyone ever tried to convert one of these filters to a
wire mesh type?  If so, what did you use?  Most of the
materials I have looked at (e.g. bronze wool, "Chore Boy" pads)
look as though they would shed small bits of metal.

Has anyone else come up with a better type of filter for
this setup?

Thanks in advance,
