Replacing the engine air filter is a maintenance item that can often be overlooked, but a dirty air filter can have a negative effect on your car’s performance.

Modern cars will generally have two air filters: one for the cabin and one for the engine. The cabin air filter also needs to be changed periodically, but on a different schedule than the engine air filter.

The purpose of the engine air filter is to prevent dust, dirt and other environmental contaminants from getting into the engine. Over time, the air filter becomes dirty and clogged, and will need to be replaced.
