Like any other piece of power equipment, chainsaws need three key components to function. The key components needed to run are fire, fuel, and air. If any of these three components are not present in the correct specification, the chainsaw will not run properly, or it may not run at all.

The component that I will be discussing as the topic of this article is the spark plug. More specifically, what kind of spark plug does a Stihl chainsaw use.

Stihl Chainsaws use two different spark plugs depending on the chainsaw model. The NGK BPMR7A and the NGK CMR6H are the two spark plugs used in Stihl chainsaws.

The NGK BPMR7A spark plug is the correct spark plug for the following Stihl Chainsaws: 017, 019, MS170, MS180, MS191, MS192, 024, MS240, 025, MS250, 026, MS260, MS261, MS270, MS271, 028, MS280, 029, MS290, MS291, 031, MS310, MS311, 039, MS390, MS391, 036, MS360, MS361, 044, MS440, MS441, 046, MS460, MS461, 066, MS660, MS661, 088, MS880, MS881.
