Bosch EVO spark plugs are 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. Bosch EVO spark plugs are developed and produced with the same high quality as original equipment spark plugs. Today’s turbocharged direct injection engines place high demands on spark plugs - the new Bosch EVO meets these needs.

With its roots dating back to 1886, Bosch is a well-established German company famous for its innovative and high-quality automotive components.
