Give your Royal Enfield Continental GT 535 a reliable ignition upgrade with a genuine NGK Iridium spark plug.

Developed for the 535cc UCE single-cylinder engine, this NGK Iridium plug features a fine iridium centre electrode designed to provide excellent ignitability, easier starting, consistent combustion and reduced electrode wear.

The Continental GT 535 was Royal Enfield’s original modern café racer, introduced with a 535cc UCE single-cylinder engine and Harris Performance-developed chassis.

Why NGK Iridium?

NGK’s Iridium technology uses a fine centre electrode to help produce a strong, focused spark while reducing electrode wear. This can support:

• ⚡ Reliable ignition
• 🔥 Better ignitability
• 🏍️ Consistent combustion
• 🔑 Easier starting
• 🛡️ Reduced electrode wear
• 🔧 Long service life

⚠️ Important Fitment Note

This product is specifically for the Royal Enfield Continental GT 535, the earlier 535cc UCE café racer.

Do not confuse it with the later Continental GT 650 Twin.

The GT 650 uses the completely different 648cc parallel-twin engine and requires a different spark-plug application. Royal Enfield’s current documentation identifies the GT 650 as a 648cc twin-cylinder motorcycle.

Quantity

The Continental GT 535 has a single-cylinder engine, so one spark plug is required per motorcycle.

Optimized for Modern E20 Fuel

Frequently Asked Questions

How often should I replace NGK Iridium spark plugs?

Typically every 40,000–80,000 km depending on riding conditions and manufacturer recommendations.
