BYD 473QE 1.5L Ignition Coil 473QE-3705100 OEM Replacement for Improved Performance

BYD 473QE 1.5L engines (e.g., F3, L3, G3) owners; if acceleration response is slow or idle is unstable, ignition coil OEM 473QE-3705100 is a direct upgrade. Compared to OEM, uses high-purity copper windings and reinforced insulation resin packaging, with better high-temperature resistance and aging performance; measured service life about 30% longer. Converts low voltage to high voltage pulses to ignite the mixture and boost ignition energy. Replacement difficulty medium; disconnect old plug, follow sequence for installation.
