PACK OF 10 CHAMPION N4C SPARK PLUGS

The Champion N4C is a spark plug particularly appealing for classic motorcycles, vintage projects, and simple engines where reliability is the top priority. It fits well in carbureted engines and less demanding setups that need to start consistently.

Features of the N4C

• Copper core that helps control the electrode temperature.
• Durable electrode, designed for less refined combustions and imperfect mixtures.
• Internal resistance to minimize electrical noise in old or refurbished installations.
• Anti-corrosion finish to protect the spark plug body against moisture and time.

Advantages in Classic Motorcycles

• More reliable starts after long periods of inactivity.
• Stable performance even in engines with veteran carburetors.
• Tolerance to imperfect mixture and idle adjustments.
• Good value for money for regular maintenance.

Ideal for Projects and Restorations

If you're updating a classic bike, a homemade scrambler, or a workshop project, the N4C is a straightforward option to kickstart the ignition system on the right foot. It pairs well with new cables and caps to ensure a healthy spark.

Installation and Maintenance

• Confirm that the N4C reference matches your engine.
• Adjust the electrode gap to the value recommended by the manufacturer or the tuner.
• Do not overtighten: respect the torque to avoid damaging the cylinder head.
• Regularly check the color of the spark plug to adjust the mixture and carburetion.

The Champion Brand in Your Classic

Installing a Champion spark plug in a classic motorcycle is almost a nod to automotive history. The N4C blends that tradition with modern materials to give you a reliable spark in an engine with years of battle under its belt.
