Hi Pepper
I am on the fence, but if I was doing it I would use BMC over K&N.
Benefits
May give you 2 or 3 HP over the stock paper filters.
May give you an extra 1 or 2 MPG over stock.
You will never have to buy another filter ever again.
May give the engine a more aggressive sound at W.O.T.
Disadvantages
May let more dirt into the engine, shortening its life.
May contaminate the Mass Airflow sensors over time.

Benefits
May give you 2 or 3 HP over the stock paper filters. - doubtful even if you won't notice a difference
May give you an extra 1 or 2 MPG over stock. - saw no gains with the bmc, only less gas mileage
You will never have to buy another filter ever again. - the only true benefit of a drop in
May give the engine a more aggressive sound at W.O.T. - no sound change whatsoever
Disadvantages
May let more dirt into the engine, shortening its life.
May contaminate the Mass Airflow sensors over time. - it's a filter, it will filter out the same as the oem filter

I have the K&N in my 993 for sound and like it so I tried the BMC in my cayenne.
I noticed no difference in sound or seat of the pants driving so I put the oem back in for warranty purposes.

Thats true pct, but I was thinking more about the possibility of oil contamination from the pre oiled filter.
This may or may not be a problem, but I thought it should be mentioned.
