Spark Plugs

Today’s turbocharged gasoline direct injection engines place high demands on spark plugs. To meet these needs, the new Bosch EVO spark plug 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.

Bosch Double Iridium Spark Plugs are engineered to deliver both high performance and long life, representing advanced original equipment (OE) spark plug technology. The ultra-fine wire design and laser welded tapered ground electrode deliver optimum performance, while the iridium center electrode and ground electrode help it to go the distance. Unlock the performance in your engine with Bosch Double Iridium Spark Plugs.
