Robert Bosch has introduced the new EVO spark plug engineered to ensure reliable ignition throughout its long service life.

To meet the needs of modern turbocharged gasoline direct-injection engines placing high demands on spark plugs, Robert Bosch LLC has introduced the new EVO spark plug. It is engineered to ensure reliable ignition throughout its long service life – even under extreme conditions in modern engines. 

Thanks to its improved insulator design and high dielectric strength (greater than 45 kV), the new EVO spark plugs can withstand irregular combustion – known as mega knocking – that can occur in modern, technologically advanced engines.

The EVO spark plug features:

  • A laser-welded iridium alloy pin on the center electrode and a platinum-iridium alloy plate on the ground electrode, ensuring long service life and high wear resistance

  • An improved insulator and housing design for increased head-bending strength, reducing the chance for damage during installation and optimizing gas seal tightness in the cylinder head

  • Thermomechanical, mechanical and electrical strength to withstand increased pressure during mega knocking 

Bosch works closely with original equipment manufacturers to develop spark plugs geared to each manufacturers’ specific, demanding requirements of the engine. The first release of EVO spark plugs will be for modern gasoline direct-injection engines in Mercedes-Benz vehicles, marking the beginning of a portfolio expansion.

Bosch EVO Spark Plugs are manufactured at the Bosch plant in Bamberg, Germany. For more information, visit www.BoschAutoParts.com
