## Description

From the racetrack to the road - Bosch technology made history in 1902 by patenting the first spark plug. Since then, Bosch's ignition expertise has grown for you to experience reliable cold-starting performance even on the coldest days. Designed with iridium at the center and ground electrodes to enhance lifetime, the spark plugs have excellent ignitability, ensuring that your vehicle has lag-free acceleration and high-wear resistance. The special ceramic material used is wear-resistant and also incorporates surface air-gap technology, providing a shield against carbon fouling. Moreover, the anti-seize nickel-plated housing and thread offer additional protection against corrosion.Bosch spark plugs are not only built to last, but are also easy to replace. The pre-set electrode gap means no further adjustments are needed. When installing the spark plug, you will need a torque wrench and must precisely observe the tightening torque indicated on the packaging to avoid damaging the spark plug or the engine. Always refer to the instruction manual for guidance. Bosch spark plugs are individually designed to fit each type of engine.
