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.

Product Features:
  • 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
