🔧 GRP Fan Shroud Type 4 Porsche Style for Base Plate

Description

This Porsche-style GRP fan shroud is the ideal base for high-performance Type 4 engines in an upright fan system.

Its extra-wide design makes it perfect for large-volume engines up to approx. 3 liters, offering ample space for performance-oriented setups and ensuring clean integration into the engine bay.

The surface is black and deliberately designed to be excellent for individual further processing such as painting or finishing. This allows the fan shroud to be optimally adapted to the respective vehicle concept.

Designed for outer rings with a 260 mm diameter, the fan shroud fits perfectly into common upright fan systems. For final installation, individual adjustments such as cutouts and spark plug clearances are necessary – as is common with performance modifications.

A perfect foundation for high-quality and individual Porsche-style Type 4 conversions. 🤙

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.
