K&N Air filter in CRD

Has anyone replaced the factory air filter with the K&N drop in air filter? Any performance increase? Sound?

Last time I checked K&N did not offer a filter for the 3.0L. I sent in a request to make one.

They do in-fact manufacture a drop-in filter. I was even able to purchase it at Advance Auto Parts. For reference, it's the same model number as the K&N Drop-In Filter for the 2.8 CRD in the Liberty.

-As far as performance, etc. you can hear the turbo sucking lots of air, though it equates to muffling the sound of a vacuum cleaner and hearing the air rush through the hose (i.e. VERY RESTRICTED).

I can't say that I've observed any noticeable difference which I equate to having only 7k miles on my engine thus far. K&N states that the dyno-measured gains were 6hp and 6tq.

I'm averaging 20mpg city and 20mpg hwy.

Just some food for thought http://www.bobistheoilguy.com/airfilter/airtest1.htm I'm not anti performance filters, I've used several K&N on my autos. It's not the most scientific of tests but it's worth a read. when my filter needs replacing I think I'll try the Amsoil Ea filter.
