What does the trivalent metal plating do on these spark plugs?

The trivalent metal plating on these NGK spark plugs offers excellent resistance to corrosion and seizing. This feature ensures that the plugs are easier to install and remove, even after extended periods in the engine.

Why is the copper core important in these spark plugs?

The solid 98% pure copper core is crucial for effective heat dissipation and conductivity. This helps the spark plug maintain an optimal operating temperature, contributing to reliable performance and longevity.

What does it mean that this plug has a 'hotter heat range' for certain Suzuki models?

A hotter heat range means the spark plug transfers heat away from the firing tip less efficiently. For specific 1988-1998 Suzuki M/C applications, this hotter range is specified by the manufacturer to help prevent fouling and ensure proper ignition under certain operating conditions.
