Check the filtration efficiency of a K&N filter vs. that of any other pleated paper air filter for an engine application. You will be surprised that the efficiency of the K&N is very low. You can even see through it on a bright sunny day.

The only time a K&N has an advantage is at maximum engine speed. All paper filters are sized for twice the normal air flow to allow for proper flow after the filter loads with particulate.

Any one that operates an engine without out an air filter certainly doesn't know any thing about engines! The same goes for anyone using a K&N filter. Henry Ford knew that no filter on his Fords was certainly going to sell cars down the road.

I spent all my years as an engineer with Diesel, gas, and gas turbine engines for all kinds of applications. Don't tell me about filters!
