OYEAUTO Iridium Spark Plug Ignition Coil Pack Set for Toyota Prius, Corolla, Matrix

Several potential symptoms may indicate an ignition coil problem. These include engine misfires, rough idling, poor fuel economy, difficulty starting the engine, a check engine light illuminating, exhaust backfiring, and fuel leaks.

The benefits of iridium spark plugs are numerous. They can improve the acceleration profile, provide more engine power, and enhance fuel economy. Iridium plugs also require less voltage than other designs, offering greater durability and corrosion resistance.

The package includes 4 ignition coils and 4 iridium spark plugs. It is important to note that when using iridium plugs, one should not touch or attempt to adjust them, as the delicate tip is easily broken. These plugs come pre-gapped, so it is crucial to ensure everything is in order. Additionally, there is a trivalent plating on the spark plug threads, and the use of anti-seize should be avoided, as it can affect the torque values and potentially cause issues.

The replacement coil pack numbers include UF596, UF619, 90919-02252, 90919-02258, 9091902252, 9091902258, 921-2126, 178-8502, 19205439, E1096, E1119, CLS1172, 36-8152, 19205156, 19205439, C1714, 5C1771, E1096, GN10341, and 673-1310.
