Folks,
complete newbie here; i just bought my 2011 x5 50i two days ago;
the car is amazing, however the exhaust note is week;(
i was thinking to do of what i usually do [with other cars]: replace the air filters with K&N and disconnect the batter to reset the computer settings..
that seems to be weirdly odd for the x5 as the filters are hidden;
is it worth it?
is it that easy as i think it is?
i found that the K&N has the filters available for sale.., below is the link

thanks,
chris
