Air Filters

Air filter Prevents harmful debris, dirt and contaminants from entering your engine. What follows is a brief description of the most basic aspects of a car air filter.


The main purpose of an automotive air filter is to filter and clean outside air before it gets sucked into a car engine and burned along with fuel to produce combustion.

Air that gets sucked into a car engine needs to be as clean as possible to prevent engine contamination and, in some cases, engine damage. An air filter is the main line of defense against preventing damaging particulate matter from entering a vehicle’s engine.

How Often Should It Be Changed?

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.

How often the engine air filter will need replacement varies. The engine air filter should be replaced between 24,000 and 48,000 Kms, depending on driving conditions.

You might be able to tell when a filter needs replacing just by looking at it. If you find black areas on the section through which outside air enters, then it may be time for replacement.

Why Replace Air Filters?

A clean, properly installed and functioning air filter increases both engine performance and gas mileage. By filtering incoming air into an engine, an air filter ensures that air burned inside of an engine is as clean as possible. Clean, purified air ignites quicker and better inside of an engine cylinder, an occurrence that increases engine combustion efficiency, which increases fuel economy
