Chery QQ6 473 Engine High-Voltage Ignition Coil S12-3707130BA Long Rod Design

Chery QQ6 (S12 series) and 473-engine-equipped models (e.g., some Flagship Yun and Sanyang) use original high-voltage ignition coil OEM 3707130BA. Long-rod design mounted above the cylinder head, directly connects to spark plugs, converting low voltage to high voltage to ensure ignition system operation. Installation difficulty: medium. Labor about 0.5-1 hour. Pay attention to the connection order of high-voltage wires. If vehicle exhibits weak acceleration, rough idle, hard starting, or engine check light on with aging high-voltage wires, replace to restore power stability.
