Special Spark Plug 12420480 (Genuine DEUTZ/MWM Part)

Part No. 12420480 is a dual iridium spark plug specially for DEUTZ MWM gas engines. It is an original genuine part for reliable ignition of natural gas, biogas and other gaseous fuels, compatible with TBG/TCG series gas engines.

1. Basic Information

  • Part Number: 12420480
  • Name: Gas Engine Spark Plug
  • Brand: DEUTZ / MWM
  • Applicable Models:

    DEUTZ MWM TBG 616/620 gas engines

    DEUTZ MWM TCG 2016/2020/2032 series

    Suitable for industrial gas units running on natural gas, biogas, landfill gas, etc.
  • Function: Ignite air-fuel mixture to ensure stable ignition, efficient combustion and low emissions.
  • Matching Parts: Core component of valve train and ignition system, used together with rocker arm assembly 12420479 and cylinder head gasket 12420482.

2. Material & Manufacturing Process

  • Electrode Material: Dual iridium electrodes (both central and ground electrodes). Features high melting point, excellent erosion resistance and long service life.
  • Shell Material: High-strength alloy steel with good corrosion resistance and vibration resistance.
  • Insulator: High-purity alumina ceramic, high temperature resistant and superior in insulation performance.
  • Resistor: Built-in 5kΩ damping resistor to suppress electromagnetic interference.
  • Operating Temperature: -40℃ ~ +650℃, applicable to gas engines under high explosion pressure and high temperature conditions.
  • Heat Rating: 77 (high heat rating for continuous heavy-duty operation).

3. Key Dimensions (Original Standard)

  • Thread Specification: M18×1.5
  • Thread Length (Insertion Depth): 20.6 mm
  • Hex Size: 20.8 mm
  • Electrode Gap: 0.3 mm (cold condition)
  • Sealing Type: Metal gasket sealing
  • Unit Weight: Approx. 0.5 kg

4. Functions & Features

  • Long Service Life: Dual iridium electrodes achieve a service life of 8000–10000 hours, reducing downtime and replacement frequency.
  • Stable Ignition: Precise gap and concentrated spark ensure reliable ignition under low temperature and heavy load, avoiding misfire.
  • Vibration Resistance: Reinforced shell and electrode structure adapt to severe vibration of industrial engines.
  • Wide Compatibility: Works well with natural gas, biogas, coal bed gas and other gaseous fuels, and resists carbon deposition and coking.
  • Low Interference: Built-in damping resistor protects ignition modules and electronic control systems.

5. Replacement & Compatibility

  • Genuine Alternative Part No.: 12420480 (No updated replacement part)
  • Equivalent Models:

    BO SCH: 0242356515 / MR3DII360

    DENSO: GL3-3 / GL35

    BERU: 18GZ5-77-5
  • Recommended Aftermarket Brands: BO SCH, DENSO, BERU. Thread specification, electrode gap, heat rating and electrode material must be fully matched.

6. Installation Instructions

  1. Inspection & Cleaning: Check the insulator for cracks, electrodes for erosion and oil contamination, and threads for integrity.
  2. Installation Torque: 70±5 Nm (cold condition). Do not over-tighten to prevent damage.
  3. Gap Check: Confirm the electrode gap is 0.3 mm before installation and adjust if out of tolerance.
  4. Sealing Check: Ensure the gasket is flat and threaded holes on cylinder head are clean to prevent air leakage.
  5. Replacement Cycle: Replace every 8000 operating hours or 12 months, whichever comes first. Complete set replacement is recommended.
