- Bosch EVO Spark Plug
- Thermomechanical strength: Improved insulator design features provide greater resistance to irregular burns and mega-knocking
- Mechanical strength: Improved design features on the insulator and housing increase the head bending strength, reducing risk of damage during installation and optimizing gas seal tightness in the cylinder head
- Electrical strength: Improved design features on the insulator increase the dielectric strength (>45kV)
- Long service life: The iridium alloy in the firing pin of the center electrode and platinum-iridium alloy on the ground electrode reduces the wear on the electrodes and increases the service life of the spark plug
- Corrosion defense: Improved corrosion protection through the use of a process developed by Bosch for nickel coating of the spark plug housing
- Important: Always torque to the proper specification using a torque wrench
- 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 gasoline direct injection engines place high demands on spark plugs - the new Bosch EVO meets these needs.
