NGK 92274 (LKAR7AHXS) ruthenium spark plug for Nissan, Mazda, Honda, Infiniti and Acura – 1 piece

Ruthenium Spark Plug NGK 92274 (LKAR7AHXS) for Nissan Mazda Honda Infiniti Acura 1 pc

Maximum Ignitability and Spark Stability

The high-tech Ruthenium HX series spark plug ensures stable operation of gasoline internal combustion engines across a wide range of loads. The use of the rare-earth precious metal ruthenium for coating the central electrode allows achieving high spark temperature and resistance to burnout. The tip geometry promotes rapid flame front propagation in the combustion chamber, reducing misfires during cold starts and intense vehicle acceleration.

The use of an original Japanese-developed spark element optimizes the power unit's operating cycle. Using this part provides the following practical results:

• Efficient combustion of the fuel-air mixture thanks to the ultra-thin central electrode.

• Reduced load on ignition coils due to the low voltage required to bridge the spark gap.

• Confident start of the gasoline engine at extremely low ambient temperatures.

• Prevention of carbon and soot formation on the insulator due to its quick self-cleaning ability.

The metal body of the element is equipped with a reliable anti-corrosion coating that protects the threaded part from seizing to the cylinder head and facilitates subsequent removal during scheduled maintenance.

Factory Durability and Protection Against Thermal Overloads

The design of this spark plug model is aimed at ensuring a long lifespan in modern forced and atmospheric engines. The ceramic insulator has increased mechanical strength and withstands sharp temperature fluctuations, eliminating current leakage to the body. The internal copper core effectively dissipates excess heat from the working area, preventing the occurrence of engine-damaging pre-ignition.

The stable geometry of the electrode gap is maintained throughout the entire manufacturer-specified service life. The technological execution of the spark plug is characterized by the following key parameters:

• Presence of a resistor for effective suppression of radio interference affecting the vehicle's onboard electronics.

• Profiled ground electrode to minimize the effect of spark quenching by the chamber walls.

• Molded sealing ring for combustion chamber sealing and prevention of gas breakthrough.

• Precise laser welding of elements, eliminating hidden defects in the connection of precious metal to the base.

The product is supplied in an individual factory cardboard box, protecting the thread and electrodes from mechanical damage during transportation across Ukraine. The part is fully ready for installation while maintaining the factory gap.

Detailed Applicability Map for Japanese and American Cars

This type of spark plug has an extended threaded part and is widely used in power units of leading Asian and premium American car brands. Verification of technical parameters ensures correct installation.

Before installing the element, it is recommended to use a specialized torque wrench to comply with the tightening torque specified by the vehicle manufacturer.
