What Does an Engine Air Filter Do?

Before you take down your ride, it is very important to understand the critical function of your engine air filter. This element acts like a safety net for your engine letting it filter out the dirt, dust, pollen and any other airborne debris before they can make it to the combustion chamber. Clean air filter helps in making sure that your engine gets the right air-to-fuel ratio, which is needed to have efficient combustion and optimal performance.

When the air filter on your engine gets clogged or dirty, it will limit the air intake to your engine and cause that engine to strain itself to bring in the required air. This increased load may result in poor fuel economy, low acceleration and possible eventual engine damage. The air filter is a crucial component of the engine’s intake system that directly impacts performance.
