Motortech B4321 MHP spark plug- Box of 4

Suitable for MAN engines, can be used for biogas and natural gas applications

Key Design Features

• Removable threaded brass SAE terminal
• Long aluminum oxide ceramic insulator offers best
  flashover protection, especially in combination with
  PolyMot™ spark plug leads and extensions
  
• Integrated stress resistant monolithic resistor
  suppresses electromagnetic interference (EMI)
•  Unified hex size reduces amount of required
  service tools for installation
• J-type electrode design and use of higher erosion
  resistance materials ensure better combustion
  particularly on lean burn gas engines and longest service life
• Copper cored center electrode with laser welded IRIDIUM alloy disc
• Copper cored ground electrode with laser welded IRIDIUM alloy disc
