58mm TB air filter option...

[SFfiredog]

I had Outerwears make these TB covers for a TWM set up I'm building.
They had the patterns made originally for Kinsler Injection.
Took a week and was $89.95.
Many colors available.
Not as totally effective as a full-on air filter but these should filter out 99.5% of any harmful stuff on the way to your combustion chambers and have zero restricton on your intake tract.
HTH,

Here are a couple of non restrictive, clean looking options. The screen machined into the base of the air horn is #14 304 stainless. Another piece of #16 304 stainless can be added on top of the #14 that will filter, can be removed to be cleaned, and won't hurt performance. The air horn top filters are the same screen and don't hurt performance. Both were run on a dyno. We can machine the horns and supply both.
