What is the role of your air filter?
The air filter is designed to trap damaging dirt and debris to prevent damage to internal engine
parts (pistons, cylinders, etc.). If even a tiny particle of dust gets into the internal components of
the engine, it can result in potentially expensive engine repairs.
When does your air filter need to be changed?
The general timeline to change your air filter is approximately every 30,000 miles. If you drive
off-road often or live in an area with high pollution rates you should replace it sooner. If you
find black or dark areas in the creases of your air filter, it is time to replace it. If you are unable to
tell by just looking at it, and it has been more than 3 years or 30,000 miles, it is time to
Why does your air filter need to be replaced?
1. Fuel Economy and Engine Performance
Optimum air flow is vital to engine performance. Clogged air filters restrict the airflow to the
engine. This causes an incorrect air-fuel mixture that can cause spark plug ignition problems in
gasoline engines and cause drive-ability issues in diesel engines. These issues can result in a
rough idle or a decrease in acceleration power. You can be experiencing issues with clogged air
filters if you notice your vehicle does not accelerate as well as it used to or sounds different
when it idles.
2. Reduced Emissions
The reduced air flow doesn’t just impact the engine, it also affects the emissions control system.
It can increase engine deposits caused by having too rich of a fuel mixture. Increased air flow to
the engine allows it to operate properly, thereby reducing emissions.
