NGK Spark Plugs
NGK has been making spark plugs since 1936, and if you've ridden a bike from almost any major manufacturer, there's a good chance NGK built the plug it left the factory with. That OEM relationship is what makes their iridium spark plug ngk range worth trusting over lesser-known alternatives: these aren't parts built to a generic spec, they're built to the same tolerances manufacturers use in production.
Within their lineup, the NGK Iridium IX spark plug is the one most riders reach for when upgrading from a stock copper plug, using a fine 0.6mm iridium alloy tip for sharper ignition and a longer service life.
- OEM to major manufacturers: NGK supplies spark plugs directly to Honda, Royal Enfield, Bajaj, TVS, and several other brands.
- Iridium IX technology: A fine iridium alloy tip, laser welded for durability and precise ignition.
- Decades of manufacturing expertise: In continuous production since 1936, with operations across five continents.
- Wide model coverage: Spark plug iridium NGK options available for most motorcycles sold in India.
What Makes the NGK Iridium IX Range Different
Standard NGK plugs use a nickel-alloy electrode, which works fine but wears down faster under heat and repeated firing. The Iridium IX line replaces that with a fine iridium alloy tip, laser welded onto the electrode for a stronger bond than a plug built by simpler methods. The result is a plug that fires more consistently over its lifespan and holds up to the heat cycles of daily riding better than a standard plug. It's the line most riders mean when they ask for an ngk iridium ix spark plug by name, and it's what you'll find stocked across most of the bike models on this page.
FAQs
Q1: What's the difference between NGK's standard plugs and the Iridium IX range?
A1: Standard NGK plugs use a nickel-alloy electrode, while the Iridium IX range uses a finer iridium alloy tip that's laser welded for durability. The Iridium IX plugs generally last longer and provide more consistent ignition, which is why they're the more popular upgrade choice.
Q2: Is NGK the original equipment brand for my bike?
A2: NGK supplies spark plugs to most major manufacturers in India, including Royal Enfield, Bajaj, TVS, Honda, and Hero, among others. Check your bike's spark plug part number against the listings here to confirm the exact NGK equivalent for your model.
Q3: How do I identify a genuine NGK iridium spark plug?
A3: Genuine NGK plugs carry a laser-etched part number on the ceramic insulator, along with the NGK logo stamped into the metal shell. If a plug you're considering doesn't have clearly marked, legible engravings, it's worth double-checking the source before buying.
Q4: Are NGK iridium spark plugs compatible with BS6 bikes?
A4: Yes, NGK's current iridium range is built to work with fuel injection systems and oxygen sensors used in BS6-compliant motorcycles, alongside older BS4 carbureted models. Always confirm the exact part number matches your bike's specification before ordering.
Q5: How long does an NGK Iridium IX spark plug typically last?
A5: Most riders get 20,000 to 25,000 kilometers out of an Iridium IX plug under normal conditions, though this varies with riding style and engine condition. Regular servicing and clean air and fuel systems both help the plug reach its full lifespan.
