High-quality iridium center electrode

The NGK IFR7X7G spark plug is equipped with an iridium center electrode. Iridium has an extremely high melting point, resulting in a durable and stable spark. This contributes to more efficient combustion and better engine performance.

Superior anti-corrosion properties

Thanks to the trivalent metal plating, this spark plug offers excellent protection against corrosion and seizing. This ensures a longer lifespan and reliability of the spark plug, even under tough conditions.

Advanced construction for optimal performance

The spark plug features a laser-welded iridium center electrode and a platinum disc on the ground electrode. This combination provides a consistent spark and reduces wear, resulting in longer life and improved engine performance.
