NGK Laser Iridium Spark Plug — ILZKBR7B8G (97968)

A rough idle, hesitation under acceleration, or a check engine light with misfire codes (P0300–P0304) are common signs that your spark plugs need replacement. A worn plug degrades the ignition system, leading to incomplete combustion and placing extra strain on your ignition coils.

These are high-quality OEM spark plugs (NGK ILZKBR7B8G), featuring laser-welded iridium technology. The iridium disc is welded to the center electrode and a platinum disc is welded to the ground electrode, reducing wear on both surfaces and providing excellent durability and long life . The 98% pure copper core prevents overheating while delivering reliable starts.

 

When to Replace

• Misfires or rough idling
• Loss of power or sluggish acceleration
• Poor fuel economy
• Check engine light with P0300–P0304 codes
• Difficulty starting or rough cold starts
