When your experienced John's Automotive Care technician changes your oil, he will also inspect your air filter. You shouldn't need a new air filter at every oil change, but you will need to change it regularly. Heed your technician's auto advice if they tell you to change your air filter.

An air filter does what its name implies: it filters stuff out of the air. Air is drawn into your engine through the filter because your engine needs air to burn fuel. If the filter weren't there, a lot of dust and debris would come into the vehicle engine with the air when you are driving around San Diego. That dust and debris would get hot, burn and produce all kinds of ash and gumminess that would eventually clog up your engine.

Drop in an air filter and voilá! Problem solved.

But air filters themselves get clogged up with all the junk they clean out of the San Diego air. This doesn't allow the junk into the vehicle engine, but it does block up the airflow. A blocked airflow will reduce engine efficiency.

San Diego residents who get a charge out of the feeling of power in their engine might consider upgrading their air filter. Talk to your friendly and knowledgeable John's Automotive Care service advisor. Premium air filters have been proven to increase horsepower and torque. So with the cost of a premium air filter, you can increase the horsepower in your engine — there's no cheaper way to do that!

It's also one of the simplest elements of routine preventive maintenance – and it protects against damage to expensive vehicle electronic systems. No San Diego resident should have an excuse to drive around CA roads and highways with a dirty air filter.
