Measuring 36 x 28.8 x 4.8 inches, the coil features a robust male plug‑in connector that eliminates the need for wiring modifications. Constructed from high‑temperature resistant materials, it tolerates the heat cycles typical of mower operation while delivering a strong, consistent spark. The coil’s lightweight design—just 9.6 ounces—ensures it does not add unnecessary bulk to the engine assembly.
