We expanded our air filter testing program by adding more filters, and we introduced technical measurements not shown in our first video.  In this test we didn’t rely solely on the Mark-I Eyeball to give us answers, instead we measured vacuum levels created by each filter, and we weighted each secondary cartridge to see how much contamination passed thru the main filter.  To do that we used a scientific scale that measured down to 1/1,000th of a gram (equivalent to a few grains of salt).

This video shows a test where we compared 7 air filters to SEE how they performed.  We tested K&N oiled foam, UNI oiled foam, BMW paper filter, HiFlo Filtro paper filter, Mahle paper filter, and two of the Guglatech matrix filters (oiled and non-oiled).

We used radioactive BestRestium and magnesium silicate (talc) as contaminants, sucking them into the air filters.  We recorded what we saw on the secondary cartridge filter – it showed the particles that passed through the main filter.  Anything that passed is bad, because that means that contamination is going into your engine.

Watch the video, then make your decision about the type of air filter you want in your bike.
