Pls CHECK your OE number and model before buying ? See more product details Some situations where you may need to replace your car's ignition coil: 1. The engine fault light is on: If the car's engine fault light is on and a fault code related to the ignition coil is detected by the diagnostic equipment, such as a misfire fault code, it may mean that there is a problem with the ignition coil and it needs to be replaced. 2. Engine shaking or insufficient power: An ignition coil failure may cause incomplete combustion in one or more cylinders, causing engine shaking, weak acceleration, and setbacks during driving. For example, when accelerating, you can clearly feel that the vehicle's power output is not smooth, and there is a "thumping" feeling. 3. Increased fuel consumption: Due to incomplete combustion, the car's fuel economy will decrease and fuel consumption will increase significantly. 4. Difficult starting: The decline in the performance of the ignition coil may cause insufficient ignition energy, making it difficult to start the engine and requiring multiple attempts to start. For example, in a cold or hot car state, the engine rotates when starting but cannot ignite smoothly. 5. Ignition coil appearance damage: If the ignition coil has obvious appearance damage such as cracking, burning, corrosion, etc., it also needs to be replaced. For example, there are black burn marks on the surface of the ignition coil or the plastic shell is cracked. 6. Aging and wear: After long-term use, the insulation performance inside the ignition coil decreases, or the parts are worn, which will also affect its normal operation. Usually after a car has traveled a certain mileage (such as more than 100,000 kilometers), the ignition coil may need to be replaced due to natural aging. !!!Note!!! The replacement methods of spark plugs and ignition coils may vary for different models. Before replacing, it is recommended to consult the vehicle's maintenance manual or consult a professional auto repair technician to ensure the correctness and safety of the operation. Here are the general steps to replace the car's spark plugs and ignition coils: 1. Prepare tools: spark plug wrench, socket, torque wrench (if available), rags and other tools. 2. Vehicle cooling: Make sure the engine is in a cool state to avoid burns. 3. Disconnect the power supply: Remove the negative connection wire of the car battery to prevent accidental electric shock and damage to the electrical system. 4. Remove the ignition coil: If the ignition coil covers the spark plug, you need to carefully remove the ignition coil first. Some may have fixing screws or clips, which can be removed by loosening them. 5. Remove the old spark plug: Use a spark plug wrench or socket to twist the old spark plug out counterclockwise. 6. Clean the installation area: Use a clean rag to remove dust and debris around the spark plug mounting hole. 7. Install the new spark plug: Gently put the new spark plug into the mounting hole, turn it clockwise a few times by hand, and then tighten it with a wrench according to the specified torque. Be careful not to overtighten or over-loosen. 8. Install the ignition coil: Reinstall the ignition coil back to its original position and ensure that the connection is firm. 9. Connect the power supply: Reconnect the negative terminal of the car battery.
