Hi All,

Would like to find out how much testing after market of airfilters goes on, so far I have found K&N's filter testing details:

linky to K&N testing

So at least they test them.. What about the other manufactures?

Thoughts and comments welcome (I am weighing up what air-filter to buy but am also interested to see what testing has been done for filtering rather than BHP/flow-rates).
