As an avid car enthusiast, I have learned the importance of having proper spark plug wires when upgrading to headers. Headers are a popular modification for performance cars, as they improve exhaust flow and increase horsepower. However, many people overlook the need for upgraded spark plug wires when installing headers. After experiencing this firsthand, I can confidently say that spark plug wires for headers are crucial for optimal engine performance.

One of the main reasons why spark plug wires for headers are necessary is because they prevent interference and misfires. Headers often create a lot of heat in the engine bay, which can cause stock spark plug wires to fail or malfunction. This can lead to a decrease in engine power and even damage to the engine over time. Upgraded spark plug wires are designed with heat-resistant materials that can withstand the high temperatures generated by headers, ensuring consistent and reliable ignition.

Additionally, headers tend to increase the distance between the spark plugs and distributor or coil packs. With longer wire lengths, resistance also increases, potentially causing weaker sparks and misfires. Upgraded spark plug wires have lower resistance levels, providing a stronger spark to ignite the fuel-air mixture in the combustion chamber. This results in improved throttle response and overall engine performance.

Furthermore, replacing stock spark plug wires with ones specifically designed for use with headers

My Buying Guide on ‘Spark Plug Wires For Headers’

When upgrading your car’s headers, it is important to also consider replacing your spark plug wires. These wires play a crucial role in ensuring efficient engine performance and can greatly affect the overall performance of your vehicle. As someone who has gone through the process of purchasing spark plug wires for headers, I have compiled a buying guide to help you make an informed decision.

Understanding Spark Plug Wires and Their Importance

Before delving into the specifics of buying spark plug wires for headers, it is important to understand their function. Spark plug wires are responsible for delivering electrical current from the distributor or ignition coil to the spark plugs. This current ignites the fuel-air mixture in the engine, creating combustion and powering your car. If these wires are faulty or old, it can result in misfires, reduced engine power, and even engine damage.

Factors to Consider

When shopping for spark plug wires for headers, there are several factors that you should consider to ensure you get the right ones for your car.

1. Compatibility

The first and most important factor is compatibility with your car’s make and model. Spark plug wires come in different sizes and lengths, so make sure to check if they are compatible with your specific vehicle before making a purchase.

2. Material

Spark plug wires are typically made from either copper or silicone. Copper wires are cheaper but have a shorter lifespan compared to silicone ones. However, silicone wires offer better insulation and can withstand higher temperatures.

3. Resistance

The resistance of spark plug wires determines how much electricity passes through them. Lower resistance means more electricity flows through, resulting in stronger sparks and better engine performance.

4. Number of Wires

Spark plug wire sets come with different numbers of wires depending on how many cylinders your car has. Make sure to check how many cylinders your car has before purchasing a set.

5. Brand Reputation

It is always advisable to go for well-known brands when purchasing spark plug wires for headers as they tend to have better quality control measures in place and offer warranties for their products.

Tips on Installation

Proper installation is crucial when it comes to getting maximum performance from your spark plug wires for headers. Here are some tips to keep in mind:

  • Always follow the manufacturer’s instructions.
  • Clean any dirt or debris from the area before installation.
  • Avoid twisting or bending the wire too much as it can cause damage.
  • Tighten all connections properly.
  • Use dielectric grease on both ends of the wire where it connects with the distributor cap and spark plugs.
  • If using heat shield boots, make sure they are properly installed.

In conclusion, upgrading your car’s headers without replacing its spark plug wires may result in subpar performance despite having new headers installed. By considering compatibility, material, resistance, number of wires, brand reputation, and proper installation techniques, you can choose the right set of spark plug wires for your headers and ensure optimum engine performance.
