I just got a K&N filter for my Toyota 4x4.  Looking at the chart
on the back of the box, it shows flow comparisons for 4 different
filters:  Foam, Used K&N, Paper, and a New K&N.  What the chart
showed was that a used K&N did not flow as well as paper.

Now this has me thinking...

Do I need to buy a new K&N every X number of miles in order to
gain the benefits?  Will the used (even 're-charged') K&N be more
restrictive than paper?  The chart says so, at least that's how
I'm interpreting it.

I just cleaned my K&N, and those white cotton fibers aren't so white
any more.  It's got a lot of buildup in it.

Maybe the strategy is as Bob Tunnel is eluding to:  put in the 
K&N for the track, and leave the paper in for the street.

Any thoughts?
