While everything that I have read about K&N filters claims HP gains
of small to significant, I would like to raise the question of filtration.
How well does a K&N filter dirt out of an engine? Racing engines
come apart far more often than most of our Tiger engines so a little
dirt is less of a problem. What about a street engine?
The reason I ask this is a supposed Catapiller report that was posted on
another list 4 or 5 years ago. It raised some doubt in my mind. Does
anyone have any credible data?
