About Us


With a passion for Porsches and the continuous improvement of classic and vintage car performance, for over 30 years Clewett Engineering has specialized in ignition and engine management systems for high performance engines. 

We design and manufacture many specialty items for adapting older engines to modern electronic fuel injection and high-performance ignition systems. Specializing in air-cooled Porsches and a few other platforms, we produce engine management kits and components for a number of configurations and a variety of applications.

While we have an extensive catalog of parts and kits to support these upgrades and modifications, we also specialize in 1-on-1 consultations to put together the optimal solution for your vehicle and driving and performance goals.

With this technical expertise, partnerships with other quality companies in the industry, and specially designed components, we can provide a solution for almost any project.
