1.Tapered ground electrode improves combustion

2-Large copper core enables an improved heat transfer

3-Special ceramic material with high dielectric and mechanical strength

4-Specific insulator design to prevent flash overs

5-Nickel-plated shell with rolled threads provides complete anti-seize and corrosion protection

6-Fine center electrode design improves ignition 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 ignition

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.
