The PTG M178 High Flow Air Filters are a simple, effective intake upgrade for M178-powered Mercedes-AMG models. Designed to replace the factory paper filters, these performance panel filters help improve airflow while retaining an easy, factory-style installation.
PTG reports gains of up to +22 hp and +37 lb-ft of torque when used in the right supporting setup. These filters can be installed with the factory plastic inlet system or paired with the PTG M178 3 Inch Carbon Inlets for increased airflow and a more complete intake upgrade.
This is a strong first-step modification for AMG GT owners looking to improve intake efficiency without changing the full airbox system. With a reusable design and long service life, the PTG M178 High Flow Air Filters are a practical upgrade for street builds, tuned cars, and higher-power M178 applications.
