engine is able to EASILY obtain CLEAN air. The air from the atmosphere contains
lots of abrasive particles and must be removed by the filter before entering the
system. As the car ages, the air filter gets clogged up with these particles and
have to be removed. This is probably the easiest maintenance a home mechanic can
do. Basically you have to removed the air filter form it's housing and replace
it with a new one. It takes less than 1 minute! How
much easier can it be? Get your BMW
