NGK Spark Plug 7544 CR7HIX Original Equipment Quality, Stable Ignition

When your vehicle experiences idle jitter, weak acceleration, clearly rising fuel consumption, or starting difficulties, this typically indicates worn or carbon-deposited spark plug electrodes no longer firing properly. NGK 7544 CR7HIX spark plug can precisely generate a stable electric spark under normal operation, ensuring complete combustion of the air-fuel mixture and stable engine power output with good fuel efficiency. This product fits a wide range of generic models from 2000 onward, OEM number 7544 CR7HIX. Installation must use a torque wrench to tighten to standard torque to avoid over-tightening damaging the cylinder head or under-tightening causing leaks.
