I am a senior automotive technician at ASE and I can tell you that there are several brands but this brand has the best design of all. If you follow the instructions and use the appropriate tools to install them. The repair will last for the life of the engine. Whether it is a lawn mower head, an outboard motor or an aluminum head motor in your car. Available in all the sizes you need, these inserts are simply the best. A $4 stake and a bit of work versus an $800 bar head and a lot of work all for a cleaned spark plug hole. Your choice.
