Spark Plug Lead for CATERPILLAR® G3300 Series

1- The ignition coil connector contains four contact springs instead of two, leading to a more reliable connection. In addition to protecting against flashes, the resistant silicone casing also increases the durability of the connection with the ignition coil.

2- Silicone sleeve with excellent temperature and aging properties for cable outlet and spark plug well sealing.

3- Reliable terminal for best spark plug connection.

4- Much thicker insulator instead of plastic for highest dielectric strength.

5- Made from Teflon®.

6- Integrated silicone seal ring for best flash over protection.

Spark Plug Lead for CATERPILLAR® G3400 Series

1- The ignition coil connector has four contact springs providing a more reliable connection. In addition to protecting against flashes, the resistant silicone casing also increases the durability of the connection with the ignition coil.

2- Silicone sleeve with excellent temperature and aging properties for cable outlet and spark plug well sealing. The height of the spark plug insulators can be adjusted to compensate for length differences.

3- Made from Teflon® instead of much thicker insulating plastic for highest dielectric strength.

4- Ceramic spacer with 5 kΩ resistance for EMI suppression and reliable terminal for best spark plug connection.

5- Integrated silicone seal ring for best flashover protection, does not stick to spark plug insulator when removing Teflon® insulator.
