奔驰S级火花塞 0242140512 YR6NPP 33 宝马克莱斯勒日产等宽域适配

When your Mercedes-Benz S-Class or BMW etc. shows rough idle, weak acceleration, noticeably higher fuel consumption, or cold-start difficulties, this typically indicates severe spark plug electrode wear or carbon buildup; replace timely. This spark plug, under normal engine operation, is responsible for precisely igniting the air-fuel mixture to ensure complete combustion and smooth power output. OEM number 0242140512, compatible with YR6NPP 33, fits Mercedes-Benz S-Class (2000–2010), BMW 3/5 Series, Chrysler 300C, Nissan Teana, Toyota Crown, Mitsubishi Pajero and other wide-range models. When installing, torque wrench must be used per factory specs (usually 25–30 Nm) to avoid valve-cover thread damage from over-tightening or leakage from under-tightening.
