Quality that sets the benchmark: Bosch Nickel spark plugs
Equipped with a ground electrode made from nickel alloy: Bosch Nickel spark plugs are developed to the same high quality as original equipment for a wide range of applications.
High heat conductivity with ground electrode made from nickel alloy and large copper core: For a smoother engine operation and a steady acceleration
Nickel-plated housing and thread: For protection against corrosion and seizure in the aluminum cylinder head without the need for lubrication
Factory pre-set electrode gap: Enables hassle-free replacement of spark plugs
Manufactured using heat-shrink assembly: Improved resilience in extreme temperatures and ensures high gas-tightness

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.
