The E3.12 spark plug is a 14mm plug with a 0.375 - inch reach and a gasket seat. It's specifically designed for Comer C - 50, C - 51, and C - 52 engines in kid karts, offering reliable ignition performance.

Using this spark plug is easy. First, make sure your kid kart's engine is turned off and cooled down. Then, carefully remove the old spark plug and replace it with the E3.12. Tighten it gently but firmly. When using your kid kart, always keep an eye on the engine's performance. If you notice any issues like rough idling or poor acceleration, it might be time to check the spark plug. For maintenance, it's a good idea to inspect the spark plug regularly. Clean it if it gets dirty, and replace it if it shows signs of wear. This will help keep your kid kart running smoothly.
