AGS Delete

Active Grille Shutters (AGS) are a feature commonly found in modern vehicles. They are designed to improve fuel efficiency by controlling the amount of air that flows through the radiator and engine bay. However, AGS can cause issues for car owners, and removing or remapping them may offer significant benefits. In this article, we will explore what AGS are, why they can cause problems, and the benefits of AGS delete and remapping.

What are Active Grille Shutters?

Active Grille Shutters are a system that automatically opens and closes the front grille of a vehicle to control the amount of air that flows through the radiator and engine bay. The system uses sensors to determine the temperature of the engine and the airflow through the grille, and adjusts the position of the shutters accordingly.

Why can Active Grille Shutters cause Problems?

While AGS can improve fuel efficiency, they can also cause problems for car owners. The shutters can become stuck in one position, causing overheating or insufficient airflow. In addition, the AGS system can be susceptible to damage from road debris or accidents, which can result in costly repairs.

Benefits of AGS Delete and Remapping One way to avoid these problems is to remove or remap the AGS system. AGS delete involves removing the shutters from the grille and replacing them with a grille insert. This can be done by a professional mechanic or at home with an AGS delete kit.

AGS delete offers several benefits for car owners, including:

  1. Increased Airflow: By removing the AGS system, air can flow more freely through the grille and engine bay, reducing the risk of overheating and improving performance.
  2. Reduced Maintenance Costs: Removing the AGS system can reduce the need for costly repairs and maintenance associated with AGS failure.
  3. Improved Aesthetics: Some car owners prefer the appearance of a grille without shutters, and removing the AGS system can improve the overall look of the vehicle.

In addition to AGS delete, car owners may also want to consider remapping their engine control unit (ECU). ECU remapping involves modifying the settings of the car’s ECU to optimize performance. This can help unlock additional power and improve acceleration and overall performance.

When the AGS system is removed, the ECU may need to be remapped to compensate for the change in airflow. This can help ensure that the engine runs smoothly and efficiently. Remapping the ECU can also help optimize the performance of the engine and unlock additional horsepower and torque.


While Active Grille Shutters can improve fuel efficiency, they can also cause problems for car owners. AGS delete and remapping offer several benefits, including increased airflow, reduced maintenance costs, and improved aesthetics. If you’re experiencing issues with your AGS system or looking to improve the performance of your vehicle, consider AGS delete and remapping as a solution.
