I hope my thread doesn't become a filter thread. but here are my aditional two cents.
Try to breath thru a piece of paper, then thru a sponge.
I am sure that thru the sponge would be easier. This is the same with a K&N filter.
I have used them on every engine I have had. Including a 3 HP, 0.21CC Nitromethane/Methanol engine runing at 45,000 RPM pushing a 7 pound car at 60 MPH over dirt tracks and never gave me any problems. The most important thing is to apply a healthy coat of special oil and keep it oiled.
That is what makes the smaller particles stick to the filter.
K&N have a disclamer that reminds me of DC:
"K&N will not be responsible for any other expenses incurred by the customer under the terms of this warranty, nor shall it be responsible for any damages either consequential, special, contingent, or otherwise; or expenses or injury arising directly or indirectly from the use of the Filtercharger® element."
But I will keep using it, cleaning it periodicaly and applying the "Recharger" oil.
In the long run, is cheaper than the paper element. and no dealer has ever voided a waranty because they were used. At least that I know of.
Just two cents.
