K & N's

Mark, & List,

I put K & N's on both my 'merican cars and noted no change in performance or in gas mileage (I keep diligent records). . . .

356 Listers/Forumsters,
Check out this webpage on intake filtration. It's from K&N and no doubt includes some bias, but it provides a good technical overview. Specifically check out the Paper vs. K&N section. According to K&N, one reason paper filters are 'worse' than the K&N cotton is that natural humidity swells the fibers and restricts airflow. Yet, when the K&N filter traps dirt it improves the filtration. In both cases, there is added restriction yet one is better than the other.(?) One advantage of cotton over paper is the re-useability. Not trying to flame anyone, add fuel to a carb fire, or force bad puns down anyone's throat, just wanted to share the article. Maybe it will clear the air a bit.
