Do you operate a co-gen plant?  You need top quality spark plugs which outperform the competition.  DENSO is one of the world’s leading innovators for ignition technology.  DENSO provides a variety of different plugs perfect for co-gen applications.

DENSO is an automotive components manufacturer. They are one of the world’s leading innovators for ignition technology. A part that DENSO manufacturers is their Iridium CoGeneration Spark Plugs, an important part for the gas engine industry. This post will: describe Iridium Saver Plugs and give DENSO parts numbers.

There are three Iridium Saver Spark Plugs that DENSO offers. These three are: Iridium Saver, Iridium Saver Performer, and Iridium Saver DDI.


The first spark plug is the Iridium Saver. This uses original Iridium (Ir) and is the standard spark plug.

Spark Plug Failure Causes

A spark plug failure can be a result of many different things. This blog post will contain five possible reasons on why your spark plug is failing. These reasons include: carbon fouling, oil fouling, overheating, pre-ignition, and insulator breakage. Visual and written descriptions will be provided for each possible reason.

Normal Condition

Before outlining what spark plugs look when they’re failing, let’s start by looking at what a normal spark plug should look like.

Appearance:

  • The base of insulator becomes white or gray when using unleaded gasoline
  • Electrode may become burned
  • The base of insulator becomes light brown when using leaded gasoline
normal spark plug
Normal Condition

Carbon Fouling

Appearance:

  • Dried carbon deposited covering insulation base as well as electrode area

Engine:

  • Faulty engine stability at low speeds
  • Engine may die often
  • NOTE: nearly 90% of engine problems are a result from carbon fouling or oil fouling on forklift spark plugs

Causes:

  1. Incorrect thermal value
  2. Idling of the engine for too long / driving in cold temperatures
  3. Rich air-fuel mixture
  4. Clogged air filter
  5. Delay in ignition timing

Fixes:

  • Causes 1 or 2: use spark plug with a thermal value that is one level lower OR adjust engine idling.
  • Causes 3-5: perform complete readjustment and tune-up
spark plug failure
Carbon Fouling

Oil Fouling

Appearance:

  • Base of insulator and electrode becomes shiny black; covered with oil or gasoline

Engine:

  • Faulty engine stability at low speeds
  • Engine may die often
  • NOTE: nearly 90% of engine problems are a result from carbon fouling or oil fouling on forklift spark plugs

Causes:

  1. Leakage of oil into combustion chamber from frictional wear of piston rings, valve guides, or cylinder wall.
  2. Rich air-fuel mixture

Fixes:

  • For cause 1: if forklift spark plugs become wet, simply clean the plug and reinstall it. If not, the engine requires a complete overhaul.
  • For cause 2: adjust the carburetor.
spark plug failure
Oil Fouling

Overheating:

Appearance:

  • Base of the insulator will be burned and will appear bleach white from the heat
  • Electrode will be burned and become white / dark purple

Engine:

  • Engine horsepower decreases and speed falls when running at high speeds continuously as well as: driving for a long time uphill, or pulling too great a load

Causes:

  1. Incorrect thermal value of plug
  2. Use of low octane gasoline
  3. Ignition timing set too early
  4. Inappropriate cooling
  5. Poor air-fuel mixture

Fixes:

  • Cause 1: use a spark plug with a higher thermal value
  • Cause 2: use higher octane gasoline
  • Cause 3: adjust ignition timing
  • Cause 4: check the cooling system
  • Cause 5: adjust the carburetor
Overheating

Pre-ignition:

Appearance:

  • Electrode will be melted
  • Base of insulator is also melted, in extreme cases

Engine:

  • Caused by overheating
  • Temperatures in combustion chamber increase rapidly – destroying the spark plug as well as the piston head

Causes:

  1. Incorrect thermal value of plug
  2. Use of low octane gasoline
  3. Ignition timing set too early
  4. Inappropriate cooling
  5. Poor air-fuel mixture

Fixes:

  • Cause 1: use a spark plug with a higher thermal value
  • Cause 2: use higher octane gasoline
  • Cause 3: adjust ignition timing
  • Cause 4: check the cooling system
  • Cause 5: adjust the carburetor
Pre-ignition

Insulator Breakage:

Appearance:

  • Base of insulator has vertical crack
  • Appearance is similar to problems with overheating or lead fouling

Engine:

  • Engine horsepower decreases and speed falls when running at high speeds continuously as well as: driving for a long time uphill, or pulling too great a load

Causes:

  1. Incorrect thermal value of plug
  2. Ignition timing set too early
  3. Inappropriate cooling
  4. Poor air-fuel mixture

Fixes:

  • Cause 1: use a spark plug with a higher thermal value
  • Cause 2: adjust the ignition timing
  • Cause 3: check the cooling system
  • Cause 4: adjust the carburetor

How to Decode DENSO Spark Plug Numbers

How to decode spark plugs is a very common problem. This blog will outline how to decode DENSO spark plugs.

DENSO spark plugs follow a specific pattern that can be used for each and every DENSO spark plug. To decipher your DENSO spark plug, you must interpret each character within the part number. Below, a table can be seen that gives each possible character and defines what they mean. ***AN EXAMPLE CAN BE SEEN BELOW THE TABLE***

Table note: asterisks * indicate the number of characters after a specified character that need to be fulfilled in order for the description to be accurate. For example, letter A in special design could be used for part number W22EA. In comparison, letter A*** in special design could only be used for a part number with 3 characters after it such as part number QJ16AR-U, with R-U being the three characters used after ‘A’.

Here’s how to decode the Denso part numbers on our most popular spark plug. W16EXR-U11.

W 14mm thread size, 20.6mm hex size. This information was found in the second row in the table.

16 this is an indicator on a range. This means that the part number is more hot rather than cold. This information was found in the third row in the table.

E 19.0mm. This information was found in the third row of the table. This information was found in the fourth row in the table.

X Extra projected insulator nose. This information was found in the fifth row in the table.

R Resistor. This information was found in the sixth row in the table.

-U U-grooved ground electrode. This information found in the seventh row in the table.

11 1.1mm / 0.044in. This information was found in the eighth row in the table.

Second Example: SK20HR11

S: 0.7 mm diameter iridium. This was found by going to the first row of the table and finding the ‘S’ character. Note: because there are two letters before the first number, this means that we must use the ‘S’ in the first row rather than the ‘S’ in the second row.

K: 14×16.0 (ISO Small Hex plug). This was found by going to the second row of the table and finding the ‘K’ character.

20: heat range. This was found by going to the third row of the table and finding the ’20’ combination.

H: Electrode projection (8.5 mm). This was found by going to the fifth row of the table and finding the ‘H’ character.

R: With resistor. This was found by going to the sixth row of the table and finding the ‘R’ character.

11: 1.1 mm gap. This was found by going to the eighth row of the table and finding the ’11’ combination.
