How to clean spark plugs
The most expensive option is the outright replacement of the part. This is what most mechanics will propose. The price of the component varies to the brand and type of spark plug.
The least expensive option, with no need for disassembly and entailing the shortest service time, and which is an alternative to part replacement, is hydrogen treatment via the Carbon Cleaning station. This service works as a preventative treatment, recommended every 15,000 kilometers, but can also resolve existing problems in the engine.
