The Bosch Spark Plug (part number 96347) is a direct-fit replacement for 2012-2026 Mercedes-Benz, INFINITI, and Freightliner vehicles with 2.0L, 4.0L, and 3.5L engines.
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
