Intake Shootout Part Duex

[00sir]

I forgot to ask before, did anyone ever figure
out which one flowed more...???

Sponge, or Cotton?

The age old battle...

Any dyno's between the two?

I would say no need to scan and post the dynos,
the numbers are fine for me.

Thanks,

I had a link to a Japanese test of air filters. The K&N filter outflowed a foam HKS filter and the K&N filter was better at keeping out dirt between these two materials. But the best filter for power and cleanliness was the Apexi, I read it was made of a paper type element, not sure about that, but it flowed and cleaned the best of all filters.
