Mercedes-Benz W164/W221/W212/W251 Iridium Spark Plug PLKR7B8E A0041595803 Long-Life Design

If your Mercedes W164/W221/W212/W251 shows idle jitter, weak acceleration, high fuel consumption, or cold start trouble, likely spark plug electrode gap is too wide, resulting in insufficient ignition energy. The spark plug correctly ignites the intake mixture to ensure smooth engine power and good fuel economy. OEM A0041595803 (PLKR7B8E) fits Mercedes W164 (ML), W221 (S-Class), W212 (E-Class), W251 (R-Class) and other post-2000 models. Install with torque wrench to manufacturer torque; inspect ignition coil boot for aging or damage to prevent misfires from poor sealing.
