NGK G-Power Series Spark Plug 836GP High Performance Iridium Ignition

Is your vehicle experiencing rough idle, jerky acceleration, or cold-start difficulty? These symptoms typically indicate worn spark plug electrodes or heavy carbon buildup, resulting in insufficient ignition energy. When functioning properly, the spark plug generates a precise spark in the cylinder to ignite the mixture and ensure smooth engine operation and optimal fuel combustion. This product fits wide-brand models from 2000 onward, OEM number 836GP; thread size M14x1.25, seating length 26.5 mm, resistance 6 kΩ. Installation requires a torque wrench to tighten to factory torque; over-tightening can damage the cylinder head threads or under-tightening can cause leakage.
