FlyB4 Flathead Parts

In 2019, Mario Bollrath initially produced aluminum side covers for Model A/B and G28t under the name BM4. In 2020, the name FlyB4 was introduced. Since then, the program has been steadily expanding.

The products are characterized by high quality and precision and are intended to continue the long history of American Speedparts from the 1930s and 1940s in design and performance.

The provisional highlight is the aluminum cylinder head of FlyB4 for Model A/B, G28T, and the Terry Burtz engine.
