NGK Honda Ruckus / Metropolitan Iridium Spark Plug 49cc/50cc

Upgrade your Honda Ruckus or Metropolitan spark plug to iridium for cleaner combustion, better throttle response, and a plug that lasts up to 10× longer than stock.

The Details

Iridium spark plugs burn cleaner and resist wear thanks to their higher melting point — about 2500°F — which means more consistent firing and a longer lifespan. Performance gains are modest (typically 1–3%), but the smoother throttle response and long-term reliability make it one of the smartest and cheapest upgrades you can do on a Ruckus or Metro.

Important Things to Note

• Designed for Honda Ruckus and Honda Metropolitan engines
• Always gap and torque your plug correctly during install
• If your current plug is fouled, diagnose the cause before swapping
