Original NGK Iridium IX Spark Plugs (LFR6AIX-11 / 6619) - Made in Japan

The ultimate ignition system upgrade.. Stronger spark, smoother torque, and absolute reliability!

NGK Iridium IX (6619) spark plugs are globally recognized as a top choice for high-performance enthusiasts and 4x4 engines. Thanks to the laser-welded iridium tip, these spark plugs deliver a sharp and stable electrical discharge that improves fuel combustion efficiency and provides immediate engine throttle response, with a significantly longer service life than conventional OEM spark plugs.

Key Features

* Ultra-precise iridium tip reduces the electrical voltage required to produce a stronger spark, providing faster and more stable ignition even under high pressure.

* Improved fuel economy: Reduces combustion flame dispersion and allows faster and wider flame propagation inside the combustion chamber to improve efficiency.

* Sharp response and smoother torque: Provides exceptional smoothness during acceleration and reduces torque drop and hesitation at high speeds and under demanding driving conditions.

* Longer service life compared to OEM spark plugs: High-purity ceramic insulator withstands extreme temperatures and electrical stress while preventing internal spark leakage.

* Triple-layer metal anti-seize and corrosion-resistant coating: Protects the spark plug threads from corrosion and rust and prevents them from sticking to the cylinder head under high temperatures for easier removal in the future.

* Factory-set spark gap: Ready for direct installation and precisely calibrated for Toyota, Nissan, and Lexus engines.

* 100% genuine, Made in Japan
