What makes the trivalent metal plating beneficial?

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

What is the purpose of the copper core in these spark plugs?

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

Are these spark plugs suitable for all Yamaha models?

These NGK CPR9EA-9 spark plugs are specifically listed as compatible with certain Yamaha models such as the FJ-09, FJR1300ES, FZ-09, MT-09, Tracer 900, and XSR900 within specific year ranges. It's always best to verify fitment for your exact vehicle.

Product Details

The pure copper core in these NGK Standard spark plugs offers excellent heat dissipation and conductivity, helping to keep your engine running smoothly. These are the same kind of proven OE technology that customers have relied on for decades, designed specifically for original equipment applications. They come in a box of 10, making it easy to replace all your plugs at once for consistent performance across your engine.

NGK uses a high-grade alumina silicate ceramic insulator that creates a strong barrier for optimal dielectric performance, and the corrugated ribs help prevent flashover. You'll also find that the trivalent metal plating provides superior resistance to corrosion and seizing, which makes installation and removal much easier. The triple gasket sealing is also a notable feature, effectively preventing combustion gas leakage and ensuring a tight seal.

These plugs are a solid option for a wide range of vehicles, including models like the Yamaha FJ-09, FJR1300ES, and FZ-09. They are built for longer life and consistent performance, giving you peace of mind on the road.
