通用汽车点火线圈 68070492AB 替换68070492AC/AD 原厂KLP品质

GM original-style KLP quality ignition coil 68070492AB, directly replacing 68070492AC, 68070492AD and 68081914AC, compatible with multiple GM 4-cylinder engines. Mounted on the valve cover, directly connected to the spark plug, converts low voltage to high voltage to ignite the air–fuel mixture; essential for normal engine operation. Replacement difficulty: medium; typical labor 1–1.5 hours; pay attention to the sequencing of high-voltage harness connections. If acceleration is weak, idle jitter, check engine light on, or fuel consumption rises, the ignition coil may be aging or leaking.
