From the manufacturer
Bosch Spark Plug
Fuel consumption and engine performance are also dependent on spark plugs. Many leading automobile manufacturers therefore rely on the development competencies of Bosch for original equipment. Innovations from motor sports also flow into the spark plug production of series-produced passenger cars – sometimes in a modified form.
As a pioneer in the field of ignition, Bosch has comprehensive know-how and offers a wide range of products for automobiles.
1.Tapered ground electrode
Improves combustion
2-Large copper core enables an improved heat transfer
3-Special ceramic material with high dielectric and mechanical strenght
4-Specific insulator design to prevent flashovers
5-Nickel-plated shell with rolled thrads provides complete anti-seize and corrosion protection
6-Fine center electrode design improves ignitability and provides longer service life
7-Laser welded precious metal pin on the center electrode provides higher wear resistance
8-Different electrode materials for different fuel applications (e.g. Ethanol)
9-Orientated ground electrode enables the right spark position and better ignitability
Workshop tip – INSTALLATION:
1. Unbox the new spark plug
2. Do not lubricate the thread. Screw in the spark plug by hand until it is seated at the cylinder head.
3. Then the spark plug must be tightened and the mandatory, type-specific torque, e.g 23 Nm.
Bosch – Trusted in the world’s most advanced engines
– Since 1902, Bosch has set milestones in spark plug technology with innovative, performance-proven products trusted by original equipment manufacturers worldwide
