The Spark Plug

Function and choosing the right spark plug

The spark plug provides the necessary spark to ignite the air-fuel mixture in an internal combustion engine.

In addition to this basic function, the spark plug is also a good indicator for carburetor tuning. The color of the electrode can show whether the mixture is too lean or too rich.

  • A black electrode generally indicates a mixture that is too rich
  • A brown / tan electrode indicates the correct mixture
  • A light or whitish electrode indicates a mixture that is too lean (risk of a seized piston)

Which spark plug fits my engine?

When the spark plug is replaced, always check the owner’s manual. It will show which standard spark plug is installed from the factory.

This manual also includes another useful piece of information: the recommended electrode gap (usually between 0.6 and 0.9 mm). An incorrect gap can lead to misfiring.

Before even considering installing a hotter or colder spark plug, it must be ensured that the plug thread is compatible with the cylinder head and that the spark plug cap fits.

Hotter or colder spark plug?

A “hot” spark plug transfers only a small amount of heat away from the insulator tip. This is achieved through special thermal insulating materials or simply through a greater amount of insulating material. With “cold” spark plugs it is the opposite: they conduct heat away quickly and keep the insulator tip cooler.

When engine output increases, this usually leads to higher combustion temperatures. This means moving away from the ideal temperature range of the original plug, which can cause ignition problems. A colder spark plug helps counteract this effect.

Note: Installing a colder plug can also be useful when outside temperatures are very high.

Spark plugs in our shop:

Standard spark plugs, racing spark plugs, iridium spark plugs... A large selection of spark plugs from well-known manufacturers such as NGK and Brisk are available for all vehicle types. The most common references such as BR9ES, BR8HS, BR9EG or R6252K-105 are kept in stock all year round to supply as quickly as possible and, of course, at the best price.

If needed, matching spark plug caps as well as other ignition components are also available.
