How Much Does It Cost To Replace an Ignition Coil?

The typical expense for replacing an ignition coil ranges from $150 to $300, accompanied by additional labor charges falling between $70 and $140. Consequently, the comprehensive service bill may amount to a total of up to $450. In the context of newer vehicles, where each spark plug often has its dedicated coil, labor costs and the overall replacement expenditure are elevated.

The Role of the Ignition Coil:

Before we explore costs, let’s grasp the ignition coil’s role. The ignition coil is a vital component responsible for converting low-voltage power from the battery into the high-voltage power needed to spark the spark plugs. This ignition spark is crucial for combustion in the engine, driving your vehicle.

Signs Your Ignition Coil Needs Replacement:

Recognizing the signs of a failing ignition coil is key to addressing issues promptly. Common symptoms include engine misfires, rough idling, a decrease in fuel efficiency, and difficulty starting the vehicle. If you notice any of these indicators, it’s advisable to have your ignition coil inspected and replaced if necessary.

Factors Influencing Ignition Coil Replacement Cost:

Several factors contribute to the overall cost of ignition coil replacement:

  1. Car Make and Model: The type of car you drive plays a significant role in determining the cost. Luxury or imported vehicles may have more expensive replacement parts.
  2. Number of Cylinders: The number of cylinders in your engine affects the number of ignition coils required. A vehicle with more cylinders will have a higher replacement cost.
  3. Labor Charges: Labor costs vary based on your location and the shop you choose. Higher labor rates in certain areas can increase the overall expense.
  4. Quality of Replacement Parts: Opting for higher quality or OEM (Original Equipment Manufacturer) replacement parts can influence the cost. While they may be more expensive, they often provide better performance and longevity.

How to Lower Ignition Coil Replacement Costs:

  1. DIY Repairs: If you’re comfortable working on your car, replacing the ignition coil yourself can significantly reduce labor costs. However, ensure you have the necessary tools and expertise to complete the task.
  2. Shop Around for Parts: Compare prices from different suppliers for ignition coil replacement parts. Some online retailers or local auto parts stores may offer competitive rates.
  3. Multiple Coil Replacement Kits: If your vehicle has multiple ignition coils, consider purchasing a kit that includes all the needed coils. These kits are often more cost-effective than buying individual coils.
  4. Seek Multiple Quotes: Before committing to a specific auto shop, obtain quotes from multiple mechanics. This allows you to gauge the average cost in your area and potentially negotiate a more reasonable price.
  5. Regular Maintenance: Regularly servicing your vehicle and addressing ignition issues promptly can prevent more significant problems, potentially reducing long-term repair costs.

Recognizing Signs of a Faulty Ignition Coil While Driving:

When an ignition coil malfunctions, various symptoms manifest during driving, serving as crucial indicators. These include:

  1. Check Engine Light: A prominent sign of a problematic ignition coil is the illumination of the check engine light. Persistent misfires within the cylinder associated with the faulty coil often accompany this warning. Prompt attention to these symptoms can streamline the repair process.
  2. Elevated Emissions: An increase in emissions is a significant giveaway for a faulty ignition system. Consistently higher emissions, especially marked by a raw fuel smell or black smoke from the tailpipe, signals the need for a closer examination to determine if the ignition is the culprit.
  3. Decreased Fuel Efficiency: Declining fuel efficiency, coupled with difficulties during startup, indicates potential issues with the ignition. A malfunctioning cylinder puts strain on others, causing accelerated fuel consumption. Monitoring these patterns is crucial for early detection.
  4. Engine Startup Issues: If your car key turns in the ignition but the engine fails to start, a faulty ignition may be the cause. Older vehicles, particularly those with points systems, electronic coils, or distributor-less coils, are more susceptible to ignition failures. In severe cases with multiple faulty coils, the vehicle may not attempt to start at all.
  5. Acceleration Challenges: Difficulty accelerating, especially when pressing the gas pedal, can point to a problematic ignition coil. Inefficient operation in one cylinder due to a faulty component causes overall engine struggle. Signs include struggling on highways or engine stuttering during rapid acceleration.
  6. Rough Idle: A telltale sign of a faulty ignition coil is a rough idle. Shaking or vibrating more than usual when the car is stationary indicates misfires in one or more cylinders. If paired with other unusual engine behaviors, seeking professional inspection is advisable.
  7. Backfiring: Backfiring, where combustion occurs in the exhaust pipes without passing through the engine, can result from a bad ignition coil or spark plugs. This imbalance in fuel and air within the cylinders may manifest as loud noises from the exhaust pipe during driving.
  8. Jerking and Vibrating: Sensations of jerking and vibrating while driving may suggest a faulty ignition coil. Insufficient spark provision for smooth combustion in all cylinders contributes to these symptoms. Early diagnosis is crucial to prevent worsening issues.
  9. Loss of Power: A failing ignition coil can lead to a noticeable loss of power while driving. Insufficient energy reaching the spark plugs hampers combustion and power output. Sluggish performance or a discernible power loss indicates potential ignition coil issues.

What Can Cause Ignition Coil Failure?

Ignition coil failure can occur due to various reasons, each contributing to potential damage and malfunction. The primary causes include:

Damaged or Worn Spark Plugs:

One of the leading causes of ignition coil failure is the presence of bad spark plugs or plug wires. This can result in excessive current flow through the ignition coil, leading to burnout. An imbalanced fuel-to-oxygen mixture, either excessively rich or lean, can also contribute to premature ignition coil failure. Additionally, engine heat and vibrations over time can contribute to coil damage.


Prolonged exposure to vibrations can lead to damage in the ignition coil windings or insulation. This damage can result in shorts or breaks in the secondary windings. To prevent this, it’s crucial to purchase ignition coils from certified suppliers who offer high-quality products and warranties.


Excessive heat, caused by factors such as high current or under-voltage, can hinder the ignition coil’s ability to conduct electricity. If you suspect issues with the coil due to decreased responsiveness in your car, it’s essential to monitor the temperature and take immediate measures.

Wear and Tear:

Wear and tear, often associated with reduced insulation between the coil windings, is a common reason for ignition coil failure. This wear can lead to overheating, impacting the coil’s performance.

What To Do After Changing an Ignition Coil?

After changing an ignition coil, it’s important to follow these steps:

  1. Clean the Area: Clean the area around the coils to remove any debris or contaminants that may affect their performance.
  2. Check for Loose Wires or Parts: Ensure there are no loose wires or components in the ignition system. Secure all connections to prevent potential issues.
  3. Ensure Proper Seating: Confirm that all coils are properly seated and securely in place. Proper seating is crucial for optimal performance.
  4. Test the Ignition System: Conduct a thorough test of the ignition system to verify that the replacement was done correctly. Check for any signs of malfunction or irregularities.
  5. Idle and Test Drive: Allow the engine to idle for a few minutes to facilitate the breaking-in process for the new coils. Subsequently, go for a test drive to ensure the vehicle is running smoothly, without any noticeable issues.

By following these post-replacement procedures, you can contribute to the longevity and efficiency of your ignition system.
