Oil Filler for Type 4 Engines 🔧

This oil filler was specially developed for use with Type 4 engines in the VW Beetle – particularly for conversions to an upright fan system.

Made from polished aluminum and combined with a black anodized cap including an integrated dipstick, it offers a clean and functional solution for oil supply.

The upper edge of the filler opening on the engine block simultaneously defines the maximum oil fill level in the engine. This allows for easy and reliable oil level checking – without additional markings or uncertainties.

A well-engineered component for anyone building a technically clean and reliable Type 4 engine.

✔ Integrated dipstick – direct oil level check đŸ›ąïž
✔ Defined fill level – upper edge = maximum oil level
✔ High-quality finish – polished aluminum + black anodized cap ⚙
✔ Perfect for conversions – ideal for upright fan systems 🔧

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.
