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.

THE MST MISSION

MST aims to develop premium-quality automotive performance parts for enthusiasts around the world. Since 2011, MST Performance has pushed the limits of intake system design and construction through continuous innovation and rigorous testing.

From prototype to production, every MST product is dyno-tested and road-tested to ensure maximum efficiency, durability, and performance. The MST philosophy focuses on achieving strong power gains throughout the RPM range, enhancing the overall driving experience rather than chasing peak horsepower alone.

Touched base with Sean to do some coding work on my F85 X5M. Not only was he a whiz with the tech stuff, knowing his way around without any difficulty. Very rare to find someone like Sean - I happily rate and recommend this business for anyone.
