INSIDE IRIDIUM IX

A finer tip.
A precise spark.

NGK’s Iridium IX design uses a fine iridium centre-electrode tip. Its small diameter supports ignitability, while the iridium material resists electrode wear.

01 / IRIDIUM IX

Fine-wire design.

A fine iridium tip and anti-fouling design. Select the exact part recommended for your engine.

02 / OTHER IRIDIUM

Different by design.

Laser Iridium is a separate NGK range. Iridium branding alone does not make two plug codes interchangeable.

03 / MULTI-PLUG PACKS

Count every plug.

Some engines use more than one plug, sometimes with different centre and side codes. Check the complete pack contents.

Technology sources: Niterra India and NGK Iridium ranges. Construction and application vary by part.

THE CODE IS THE DETAIL

Every character
has a job.

Start with the complete plug reference, including its suffix. Then check it against your motorcycle’s exact year and engine.

Search my plug code ↗

Model, year and engine

Similar model names can use different plugs. Check the manufacturer’s application information for your version.

Thread, reach and heat range

These must match the engine’s requirements. A higher or lower heat-range number is not an automatic upgrade.

Resistor, gap and quantity

Confirm the specified resistor type and gap, plus the number of plugs required. Follow the exact installation instructions.

Can I choose any iridium plug for my motorcycle?

No. The full part number must match the engine application. Check thread diameter, reach, seat, heat range, resistor specification and gap. Use your motorcycle’s manual and the current NGK application information.

Are Iridium IX and Laser Iridium the same?

They are separate NGK product ranges. Choose by the exact plug code and approved application, rather than assuming one iridium plug replaces another.

Does one pack contain all the plugs I need?

Pack quantities differ. A single plug, a two-plug pack and a mixed three-plug kit are different listings. Read the exact contents on the product page before ordering.

How often should I replace my spark plugs?

Follow the motorcycle manufacturer’s service schedule for your engine and the specified plug type. There is no single replacement interval for every product in this collection.

Where can I check the official applications?

Use NGK India’s part finder and 2-wheeler iridium application chart. Match the exact year, engine and plug position where specified.
