Ever had to cut short a training session or a race due to a faulty spark plug? This will never happen again with the extremely robust factory spark plug and its special properties:
- Iridium centre electrode tip
- Reinforced earth electrode (against vibration and breakage)
- Special design with improved anti-rusting properties
We recommend use of the factory spark plug when fitting power-boosting parts, such as factory cylinder heads, factory silencers or the factory digital box.
