NGK Iridium IX Spark Plugs for Kawasaki Ninja ZX-6R 636cc (2019–2023)

Made for the Spirit of the Ninja

The Kawasaki Ninja ZX-6R is more than a motorcycle. Its high-revving 636cc inline-four engine, sharp handling and unmistakable supersport character make every ride something to look forward to. When it is time to service your machine, the small components responsible for ignition deserve just as much attention as the rest of the bike.

Developed with a fine iridium centre electrode, NGK Iridium IX spark plugs are designed to support reliable ignition and efficient flame development. They are a practical upgrade for riders looking for a quality iridium spark plug for their Ninja’s routine maintenance.

This listing is for four spark plugs, matching the four-cylinder engine’s required plug quantity.

Why Choose NGK Iridium IX?

• Fine iridium centre electrode: The slim centre electrode is designed to help the air-fuel mixture ignite reliably.
• Reliable ignition performance: Designed to support consistent ignition when the correct plug is fitted and the ignition system is in good condition.
• Quality engineering from NGK: Choose a recognised spark plug manufacturer for an important engine component.
• Made for your maintenance routine: Ideal for riders replacing their spark plugs as part of scheduled servicing or a wider maintenance job.
• A considered choice for enthusiasts: For riders who pay attention to the details that keep their supersport motorcycle properly maintained.

Note: Iridium spark plugs do not automatically increase horsepower, improve fuel economy or cure existing engine problems. Results depend on the motorcycle’s condition, correct fitment and overall maintenance.
