Beru

About Beru: A Century of German Ignition Engineering

Beru was founded in 1912 by Albert Ruprecht, who introduced an entirely new approach to spark plug development — one focused on improved performance, reliable combustion, and minimal emissions. From those early beginnings in Germany, Beru grew into one of the most respected names in automotive ignition and cold-start technology.

Today, Beru is the leading brand of diesel cold-start systems with an estimated worldwide market share of approximately 40% for glow plugs, and in the field of ignition technology for petrol engines, it ranks as one of the four major brands in Europe. That kind of dominance is earned through decades of relentless innovation, not marketing.

OEM Trust Across the World's Top Automakers

Beru is an original equipment manufacturer (OEM) to several major car manufacturers, including Audi, Bentley, BMW, Dodge, General Motors, Hyundai, Jeep, Lamborghini, Mercedes-Benz, and Toyota. Beru components are purpose-built for European models such as BMW, Audi, Mercedes-Benz, Volkswagen, Porsche, Mini, Volvo, and Saab. When a part leaves the Beru factory, it has already met the exacting standards of the engineers who designed the vehicles it goes into.

The main production facilities for Beru glow plugs and ignition coils are located in Ludwigsburg, Germany, where precision manufacturing and stringent quality control have been at the heart of the operation for over a century.

Ignition Technology for Petrol Engines

Beru's expertise in petrol ignition spans the full system. The brand offers compact, lightweight plug-top ignition coils alongside complete ignition systems that include ignition modules, ignition cables, and connectors. As far back as 1989, Beru foresaw the evolution of modern automobiles and launched development of coil-on-plug ignition coils to eliminate ignition distributors in favor of computer-controlled ignition systems. The result is a product line engineered for the precise timing demands of today's turbocharged and high-compression engines.

Diesel Cold-Start Mastery

For diesel drivers, few brands carry the same pedigree as Beru. The first Beru glow plug was developed in 1929, and since that time the company has dominated the market with numerous patented innovations — from self-controlling, reheatable diesel glow plugs via the Instant Start System (ISS) to the innovative Pressure Sensor Glow Plug (PSG) and the extremely heat-resistant Ceramic Glow Plug (CGP).

In 2001, Beru reached a milestone in diesel cold-start technology with the introduction of the Instant Start System, allowing diesel engines to finally start as fast as a gasoline engine when cold. Completing this ecosystem, Beru's diesel glow plug controllers work in tandem with ISS glow plugs to manage the system electronically, shutting off the glow plugs when not needed, while pressure-sensing glow plugs relay engine data to fine-tune fuel trim and ignition timing.
