Description
Take your M177 4.0L V8 Turbo engine to the next level with PTG M177 CNC Ported Heads, engineered to deliver extreme duty and the highest power potential for your AMG. These heads are meticulously machined using advanced 5-axis CNC technology, ensuring an accurate and high-performance port shape that provides optimal airflow. The PTG team goes above and beyond to overhaul your M177/M178 heads for both naturally aspirated and forced induction applications.
