I want to add my $.02 for those (like me) who use a K&N but *don't* have =
the 
ram air intake -- check that filter frequently anyway!

I installed my K&N in May just before heading out on a road trip to =
Kansas, 
Texas, California, Utah, Michigan, and Georgia before heading back to 
Colorado.  (Gawd, an M3 is a great cross country road car!)  I didn't =
think 
to check the filter until just before heading to Nationals last week.

I couldn't believe how much dirt, sand, grit, bugs, twigs, rocks, and =
other 
road debris had found their way up to the filter through the normal stock =

induction ducting.  The fins were filled to the top with crud and it was 
hard to believe *any* air was getting through.

Sure was nice to just give it a thorough cleaning (followed their 
instructions to a T) and pop it back in!  Just to be safe, I may go back =
to 
a paper filter for long cross country trips and toss in the K&N when I =
get 
to the track.
