Key Features:

Fine-Wire Iridium Center Electrode

The spark plug features a slim iridium tip that requires less voltage to ignite the air-fuel mixture. This leads to improved ignition reliability, especially during cold starts and low-speed driving conditions.

Optimized Spark Efficiency

The precisely shaped ground electrode enhances flame travel during combustion, helping the engine run more smoothly while reducing the chances of incomplete burning or misfires.

Long-Lasting Iridium Construction

Iridium’s superior hardness and heat resistance allow the electrode to maintain its shape over extended use, resulting in longer service intervals compared to conventional spark plugs.

Integrated Noise Suppression Resistor

A built-in resistor helps minimize electromagnetic interference, ensuring stable engine performance and protecting onboard electronic systems.

Anti-Corrosion Coating

The spark plug threads are treated with protective plating to resist corrosion and prevent seizure, making installation and removal easier over time.

Applications — Compatible Car Engines

The NGK BKR6EIX-11 Iridium IX spark plug is suitable for a variety of engines that require a 14 mm thread, 19 mm reach, and heat range 6 spark plug with a 1.1 mm gap. It is commonly used in both Japanese and international vehicles as a reliable OEM replacement or performance upgrade.
