Ever wonder how well different motorcycle air filters perform?  Filters come in distinct 3 types:  paper, oiled foam, and oiled cloth.  Which one is better?

Mr. BestRest takes on the challenge of testing those filters, PLUS he also tests the Guglatech Matrix Filter.

He tests the filters using radioactive BestRestium and magnesium silicate (talc).  Both are highly dangerous, but he’s willing to take the risk for the benefit of the motorcycle community.
