If you have ever been to an instant oil change place, they may have held up your BMW 540 Series air filter and asked if you would like to replace it, even if it appeared clean. What you may not know is that a clean-looking 540 Series air filter is not necessarily working well. If those technicians suggested that you change your BMW 540 Series air filter, they probably weren't trying to rip you off.

The only sure way to tell whether or not your 540 Series air filter is clogged is to blow through it.
