Set of 8NGK Ruthenium HX 92274 Spark Plugs LKAR7AHX-S for Nissan Infiniti Honda Acura Mazda

Absolute power and spark stability in any mode

The premium set of automotive spark plugs represents the latest in automotive and fuel-air mixture ignition technology. The use of the noble metal ruthenium for the central electrode allows for unmatched durability and engine stability under high loads. The ruthenium alloy has a significantly higher melting point and resistance to electrical erosion compared to standard iridium and platinum counterparts. This ensures that the plugs consistently generate a powerful spark, minimizing misfires, improving vehicle acceleration dynamics, and ensuring maximum fuel combustion in the cylinders.

The unique patented geometry of the Ruthenium HX series electrodes optimizes flame front propagation in the combustion chamber, ensuring smoother engine starts even in critically low winter temperatures.

• Innovative ruthenium electrode alloy: provides maximum working life and high wear resistance under extreme pressure.

• Improved throttle response: highly efficient spark promotes rapid ignition of the lean mixture, enhancing engine responsiveness.

• Stable performance at high temperatures: thermal characteristics are optimized to prevent pre-ignition and overheating.

• Fuel economy and eco-friendliness: optimal combustion minimizes harmful emissions in exhaust gases and reduces average gasoline consumption.

• Built-in ceramic resistor: effectively suppresses radio frequency and electromagnetic interference, protecting the car's onboard electronics from malfunctions.

The use of these plugs significantly reduces the load on the ignition coils by optimizing the required voltage to break the spark gap, thereby extending the life of the entire ignition system.

Extended service life for modern Japanese engines

The high-tech ignition set is designed to meet the stringent requirements of modern multi-valve engines of Asian car brands. The thin tip of the central electrode contributes to more efficient cleaning from carbon deposits and soot in urban operation mode with frequent stops and short trips. The metal body of the plug has a special anti-corrosion trivalent coating that completely prevents the threaded part from sticking to the cylinder head and protects the part from the negative effects of road reagents and moisture.

The design of the sealing ring guarantees the tightness of the combustion chamber, preventing gas leakage and maintaining stable compression in the cylinders throughout the declared service life.

• Trivalent metal coating of the body: protects the metal from corrosion, oxidation, and mechanical damage during installation.

• Extended threaded part: specifically designed for the requirements of modern cylinder heads of Asian passenger cars.

• Protection against carbon buildup: the geometry of the insulator and electrodes promotes natural self-cleaning from carbon residues.

• Resistance to high pressure: the mechanical strength of the plugs guarantees the integrity of the insulator under peak loads in turbocharged engines.

• Minimization of misfires: the stable spark gap maintains its parameters unchanged throughout the entire period of use.

This set of original plugs is supplied in individual protective tubes and a sturdy cardboard box, protecting the fragile electrodes and ceramic insulator from impacts during transportation. The set is fully ready for installation and does not require pre-adjustment of the electrode gap.
