96347 EVO Product Description 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. 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
