For Nissan Sunny, Tiida and other models with QG13 or QG15 engines, ignition coil 22448-4M500 can be selected; the high-voltage pack is directly mounted above the spark plug on the cylinder head, converting low voltage to high voltage to ignite the mixture. OEM number 22448-4M500, suitable for OEM-quality compatibility. Installation difficulty is moderate; estimated work time about 1 hour; observe proper disassembly order. If idle is rough, acceleration is weak, fuel consumption rises, or the engine warning light illuminates, this usually indicates ignition coil aging or breakdown; replacement is recommended.
