- In addition to these benefits, double iridium spark plugs enhance engine performance by providing a cleaner burn. This results in smoother engine operation, reduced engine knocking, and enhanced responsiveness. They also contribute to a quieter, more comfortable ride due to their ability to maintain a stable spark under varying engine conditions.

It is important for the spark plug to produce a strong and consistent spark in order for the combustion process to be efficient. Over time, the spark plug can become worn or dirty, which can affect its performance. This is why it is recommended to regularly inspect and replace spark plugs as needed to ensure optimal engine performance.

The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
