L7TJC Three-Sided Pole Spark Plug for Chainsaws & Garden Machinery

Keep your gasoline-powered garden equipment running at peak performance with the L7TJC Three-Sided Pole Spark Plug. Engineered for chainsaws, brush cutters, and lawn mowers, this spark plug delivers more reliable ignition compared to standard single-pole designs — thanks to its three-sided ground electrode that provides multiple sparking passages for consistent firing every time.

Made in Mainland China.

Why Choose a Three-Sided Pole Spark Plug?

Unlike conventional single-sided pole spark plugs, the multi-sided electrode design creates several ignition pathways simultaneously. This results in a stronger, more consistent spark, extended service life, and improved ignition reliability — keeping your outdoor power equipment starting smoothly season after season.
