Reasons to change your air filter

You should change the cabin air filter of your 2020 GMC Sierra 3500 for several reasons:

• Improved engine performance: A clean air filter allows for a greater amount of air to reach the engine, which enhances overall performance and fuel efficiency.
• Protecting the engine: A dirty or clogged air filter can restrict the airflow to the engine, which may lead to overheating and damages the engine over time.
• Enhancing the air quality inside the car: The cabin air filter helps to remove pollutants, dust, and other allergens from the air inside the car, which improves the air quality for everyone on board.
• Prolonging the life of the HVAC system: The cabin air filter also helps to keep the heating and air conditioning system running smoothly, which helps increase the efficiency of the system.
• Improving the air quality outside the car: A clean air filter improves the air quality outside the car by filtering out airborne contaminants.

By changing the air filter on a regular basis, you can ensure that your GMC Sierra 3500 engine and HVAC system are running efficiently, and that the air inside and outside the car is filtered of pollutants
