Active Grille Shutter (AGS) Delete
Modern vehicles often come fitted with an Active Grille Shutter (AGS) system, designed to open and close vents in the front grille to improve aerodynamics and emissions. While effective in theory, these systems can become problematic over time – sticking open, triggering dashboard warning lights, or restricting airflow to the radiator and intercooler.
That’s where an AGS Delete comes in. At Inverness Tuning, we offer a professional AGS removal and re-programming service that enhances reliability, airflow and performance, tailored to your vehicle.
While Active Grille Shutters are intended to boost efficiency, in real-world conditions – especially on performance-tuned cars – they can create more problems than they solve. An AGS Delete gives you predictable, unrestricted airflow and peace of mind, letting your vehicle breathe the way it was meant to. This upgrade is particularly beneficial for drivers in the Highlands who cover long distances or tow heavy loads, where consistent cooling is essential.
Deleting the Active Grille Shutter (AGS) system delivers significant gains in performance, reliability and cost-efficiency. By permanently opening the grille vents and reprogramming the ECU, an AGS delete improves engine cooling, reduces intake temperatures, and prevents common AGS fault codes or warning lights. This upgrade eliminates the risk of shutter motor failure and unwanted rattles while optimising airflow for remapped engines, upgraded intercoolers and towing applications. Drivers choose Inverness Tuning for professional Active Grille Shutter delete services because it enhances throttle response, supports better fuel economy under load, and avoids expensive OEM part replacements – making it a smart, long-term investment for any modern vehicle.
