What is the Air Filter?
Your car gets in air and passes it into the engine through the air filter. (Certain cars have more than one air filter.) The air filter removes dust, leaves, and other debris from the air before sending it into the engine where it’s mixed with fuel. The combination of air and fuel is vital for the car to run. If the air filter is dirty or clogged, it will not pass enough air into the engine, producing all sorts of problems (car may not start, engine may not run smoothly, etc.). If you use a reusable air filter (K&N), please specify that in the appointment notes, as you may just need a cleaning instead of a replacement. Unless you bought K&N filter, your car has a regular filter.

Importance of this service:
A dirty air filter is incapable of keeping dirt, dust, and debris from entering your engine. When your air filter is dirty, your cylinders and oil will both be subject to contamination from dirt particles in the air, because they have no alternate method of filtering the air. This contamination causes wear and tear on your engine, and also reduces your gas mileage and emissions.
