What does the trivalent metal plating do?

The trivalent metal plating on these NGK racing spark plugs offers excellent resistance to corrosion and seizing. This makes installation and removal easier, helping to prevent damage to the cylinder head.

Why is the copper core important in these spark plugs?

The copper core within the center electrode is crucial for effective heat removal. It helps dissipate heat away from the plug's tip, preventing it from overheating during the high-demand conditions of racing.

How many spark plugs do I need for my Suzuki RM250?

These NGK racing spark plugs are sold individually. For your 1996-2000 Suzuki RM250, you will need to purchase a box of 4 to replace all the spark plugs.

Product Details

The NGK R6918B-7 racing spark plug features a special insulator nose design that helps improve throttle response, a notable benefit when you're pushing your 1996-2000 Suzuki RM250 to its limits. These plugs are built for extreme conditions, using a pure alumina silicate ceramic insulator that offers superior strength and better heat transfer than standard ceramic. This construction also includes corrugated ribs to prevent flashover, ensuring a consistent spark even under demanding loads.

NGK uses trivalent metal plating on these plugs, which provides excellent resistance to corrosion and seizing. This means they'll install and remove more easily, a practical advantage during maintenance or rebuilds. The copper core within the center electrode is key for effective heat removal, preventing the plug from overheating during intense use. Each plug is triple-sealed to prevent any leakage, ensuring reliable performance when you need it most. These are sold individually, so be sure to order four for your RM250.
