Part #OTRS-F31SX
- Thermomechanical strength: Improved insulator design features provide greater resistance to irregular burns and mega knocking
- 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
- 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
