Spark Plug NGK BPMR7A

NGK is the top Japanese spark plug manufacturer. The BPMR7A plug suits many Stihl, Husqvarna and other branded chainsaws, lawn mowers and small engines.

Chainsaw spark plugs typically last 100–200 hours. As a rule of thumb, replace at around 100 hours to maintain peak performance and prevent hard-starting or weak combustion.

*Please check your owner’s manual for fitment before purchasing.
