I need to change my air filter on my 02 620 Dark and want to go with a K&N but am a little cornfused becuase K&N's website says 2 different filters fit.  Part Number DU-6202 and DU-9001.  The dimensions are very similiar but 9001 is slightly smaller than 6202.  Does anyone know which one is the right one?  I'm sure they would both work but I would like to get the one that fits the best.

Also, if anyone knows of an alternative to K&N please let me know.  Thanks.

Interesting.  For some reason KN lists 2 filters for your year, but only the 9001 for 2005.  As far as I know all 620s had the same airbox config so I'd choose the 9001 filter.

Or if you want to be really safe, get the Measurements for the K&N and check them against your airbox measurements.

But I'm kinda Anal about things like that
