Our Story
In 1991, the VW Beetle captivated us.
What started as a hobby quickly turned into a true passion: understanding, improving, and getting the most out of air-cooled engines.
With our background in model making and foundry craftsmanship, we began developing our own parts. The first Type 1 valve covers were just the beginning - soon followed by further development into the more precise O-ring seal.
Over the years, individual components evolved into more and more solutions: components, cylinder heads, and finally complete alternator sets for Type 1 and Type 4 engines.
To this day, what began in 1991 still drives us:
Enthusiasm for technology and performance for air-cooled VW engines.
