Car Coil Relocation: Pros, Cons, and Considerations

When it comes to automotive modifications, car coil relocation is not a topic that's commonly discussed. However, for car enthusiasts looking to improve their vehicle's performance or aesthetic appeal, coil relocation can be an interesting option. This article aims to shed light on the pros and cons of car coil relocation and provide important considerations for those contemplating this modification.

Understanding Car Coil Relocation

To understand car coil relocation, it's crucial to know what a car coil does. A car coil, also known as an ignition coil, is an essential component in a vehicle's ignition system. It functions by converting the low voltage from the car's battery into the high voltage required to ignite the fuel and air mixture in the engine's combustion chamber. In stock configurations, coils are typically installed on top of the engine or on the engine's cylinder head.

Coil relocation refers to the process of moving the ignition coils to a different location within the engine bay or even to another part of the car entirely. This modification is often performed for practical reasons or to achieve a specific aesthetic appeal.

Pros of Car Coil Relocation

1. Improved Engine Bay Aesthetics:

One of the primary reasons car enthusiasts choose to relocate their coils is to enhance the overall appearance of the engine bay. By relocating the coils, vehicle owners have the opportunity to create a cleaner and more organized engine bay. This modification can also provide better accessibility to other components, making maintenance tasks more manageable.

2. Increased Cooling and Ventilation:

Relocating the coils can potentially improve cooling and ventilation in the engine bay. In the stock configuration, coils are often located in close proximity to the engine, where heat levels can be high. Moving them to a cooler spot can help prevent heat soak issues and reduce the risk of coil failure due to excessive heat. Additionally, better airflow around the relocated coils can aid in dissipating heat effectively.

3. Enhanced Performance Potential:

In some cases, coil relocation can contribute to improved performance. By relocating the coils, enthusiasts can make room for other aftermarket performance components, such as upgraded intake systems, turbochargers, or superchargers. This extra space for modifications can unlock additional horsepower gains and allow for more extensive engine modifications.

4. Customization and Personalization:

Car enthusiasts often choose coil relocation as a means of customization. By moving the coils to a different location, owners can showcase their creativity and unique style. This modification can contribute to a personalized vehicle build, setting the car apart from others and expressing the owner's individuality.

Cons of Car Coil Relocation

1. Increased Complexity and Installation Difficulties:

Coil relocation is not a straightforward modification and may require advanced mechanical knowledge and skills. Relocating coils involves extending wiring, routing them through the engine bay, and finding suitable locations that ensure proper functionality. If not done correctly, this modification can result in poor performance, misfires, or even damage to the ignition system.

2. Potential Interference with Other Components:

Relocating coils may lead to interference with other components within the engine bay. Parts such as intake manifolds, air filters, or other engine accessories can hinder access to suitable locations for coil relocation. In some cases, modifications or relocation of other components may be necessary to accommodate the new coil placement.

3. Increased Vulnerability to Environmental Factors:

When relocating ignition coils, it is essential to keep in mind their vulnerability to environmental factors. Coils are designed to operate in specific conditions, including temperature and moisture levels. Moving them to a different location may expose them to excessive heat or moisture, which can impact their performance and lifespan. Proper weatherproofing and insulation measures need to be taken to ensure the longevity of the relocated coils.

Important Considerations for Car Coil Relocation

1. Consult with Experts:

Before deciding to relocate your coils, it is advisable to consult with automotive experts or professional mechanics who have experience with this modification. They can assess your specific vehicle and provide valuable guidance on the feasibility and potential challenges associated with coil relocation.

2. Select Proper Relocation Method:

There are various coil relocation methods available, ranging from simple DIY solutions to aftermarket kits. Each method has its advantages and limitations. It is crucial to select a method that suits your vehicle model, engine configuration, and specific requirements.

3. Understand Wiring Requirements:

Relocating coils involves extending the wiring harness, which can be complex. It is essential to have a good understanding of the electrical system and ensure proper connections and insulation to avoid electrical issues or potential hazards. If in doubt, it is best to seek professional assistance for proper wiring.

4. Test and Monitor Performance:

After completing the coil relocation, thoroughly test and monitor the performance of your vehicle. Pay attention to any changes in engine behavior, misfires, or other irregularities. If any issues arise, promptly address them to avoid potential damage to the ignition system or engine.


Car coil relocation is a modification that offers both aesthetic and performance potential. While it can improve the overall appearance of the engine bay and provide extra space for other modifications, it is not without its challenges. Proper consideration of the pros, cons, and necessary considerations mentioned in this article is crucial before embarking on this modification. With careful planning, expert advice, and proper execution, car coil relocation can be a rewarding modification for car enthusiasts seeking to enhance the look and performance of their vehicles.
