Stihl Chainsaw Spark Plugs, When you have a petrol-power tool, it is important to maintain the spark plug. STIHL chainsaws use NGK spark plugs, but there are a few key differences between them. STIHL’s spark plugs are more reliable and last longer than NGK’s. They are also tuned for the specific engine, preventing the early failure of the ignition module. Changing the STIHL chainsaw spark plug regularly will extend its life.
To change the spark plug on a Stihl chainsaw, first, remove the rubber connector. Remove the air filter cover if it is visible, and then remove the spark plug and gap it according to the manual. To remove and replace the spark plug, turn the ignition switch to the “On” position. Next, disconnect the black chain brake handle. After you have removed the black handle, insert the new spark plug.
