ABOUT MST PERFORMANCE AUTO PARTS
HISTORY
Founded in 2011 and based in Tainan, Taiwan, MST Performance was created from a lifelong passion for automotive engineering.
The founder, Mr Chiang, began his journey modifying motorcycles before moving into cars, where his desire to improve performance led him to design his own intake systems.
Starting with Ford Focus models for himself and friends, his first products delivered outstanding results and fuelled MST’s growth. A commitment to developing high-quality, performance-focused parts quickly became the cornerstone of the company’s success.
