Beru special spark plugs – Quality Under One Roof
Due to decades of experience in vehicle and heating ignition systems, Beru has become the leader in the industry and is continually improving ignition electrodes. One example of this continuing improvement is the ceramic body, specially developed to provide fracture stability and dielectric strength. Other examples are the gas-sealed electrode and the 2-part center electrode, which is reinforced through glass sealing and has a particularly high mechanical strength. Another improvement is the elongation and distortion resistance of the center electrodes in the ceramic body.
