Chain saw spark plug price:

International chain saw spark plugs usually cost about 10 yuan, and the quality is average in the spark plug series. Due to cost and loss reasons, it is rare to find full iridium or even platinum electrode materials. Most of them use a part of the electrode surface, which is considered relatively cheap. High-end.

Chain saw spark plug gap and number of poles:

There is only a gap of 0.6-1.0 mm between the center electrode of the chain saw spark plug and the ground electrode. Although the more ground electrodes there are, the wider the conductive contact surface will be. However, since the carbon deposits of the chain saw are relatively even, the number of poles will vary. There is a certain difference, but it can almost be ignored. In recent years, spark plugs with the number of poles as a selling point have appeared in the world, so you can choose appropriately.
