Does replacing spark plug wires improve performance?

Your vehicle may experience engine idling problems, poor acceleration, and many other combustion-related problems. The problem may not be in the engine, old spark plug wires are known to cause such malfunctions. Increased carbon emissions due to incomplete combustion of the air-fuel mixture and low power are also associated with faulty or worn spark plug wires. Using new and serviceable spark plug wires can greatly improve your vehicle's overall performance. The new cables properly transfer electricity to the spark plug, which in turn generates enough spark to efficiently burn the air/fuel mixture.

So yes, changing spark plugs improves performance. I have replaced countless spark plugs and spark plug wires for my clients in the garage. I'm going to discuss the various benefits of using new spark plugs. It is important to note that changing the spark plugs also requires changing the wires.

Generally speaking, spark plugs and spark plug wires are integral components of any vehicle's combustion or ignition system. They are responsible for generating the sparks needed to ignite the air-fuel mixture. Thus, if they are worn out, the combustion system may not work properly. But replacing them has many benefits, including: increased fuel efficiency, proper fuel combustion, comfortable engine starting, reduced carbon emissions, and improved power.

We will discuss each benefit in detail later in this guide. But in general, always check the condition of the spark plug and its wires. If you notice any abnormal phenomena such as large gaps, install a new set of spark plugs and cables immediately.

5 benefits of changing spark plugs

The spark plug receives electricity from other parts of the ignition system and generates a spark. An electrical spark carries a high voltage current from the ignition coil to the combustion chamber to ignite the air/fuel mixture.

Spark plugs, like any other material, are subject to physical wear or tear. So when your spark plug gets old, it's best to replace them with new ones.

It is important to understand that changing spark plugs requires new cables. This is because old spark plug cables cannot carry the high voltage current from the ignition coil to the cylinder.

There are many benefits to using fresh spark plugs in your ignition system. We will discuss five main ones.

1. Optimal combustion engine performance

Since the spark plug is one of the main components responsible for the combustion of the air/fuel mixture, damaged or worn spark plugs can damage the ignition system. This will affect the car's gas mileage and the car will consume more energy.

A new, working spark plug will improve your car's performance. So get new sets of spark plugs regularly to keep your car in good condition. You will also avoid any repairs needed due to poorly functioning spark plugs.

2. Improved fuel efficiency

According to the National Automotive Service Excellence Institute, worn spark plugs can lead to engine misfiring. What results in a 30% reduction in fuel consumption for your vehicle. Constant maintenance and refueling costs are also associated with bad spark plugs. Essentially, the gross maintenance costs will be too high for the owner.

The engine will churn more fuel before starting combustion if the spark plug is faulty. This is due to insufficient voltage being applied to the air/fuel mixture to cause ignition. Since spark plugs lose traction over time, it would be best to constantly check and replace them.

The new spark plugs will improve fuel efficiency and therefore restore both fuel economy and gas mileage.

3. Flawless startup performance

Old spark plugs affect vehicle performance. They can lead to rough idling, poor acceleration and engine idling.

Notably, aging spark plugs have large spark gaps due to wear. The consistency of the combustion system may be affected. As a result, the engine idles and accelerates poorly.

Luckily, you can prevent all of these problems by using newer spark plugs.

4. Reduce carbon emissions

Bad spark plugs put a lot of stress on a car's engine. However, fresh spark plugs have the correct gap size and will perform at optimum power. This optimum performance reduces carbon emissions while saving fuel.

For these reasons, the EPA strongly recommends regular vehicle maintenance. Consequently, higher levels of carbon in the atmosphere lead to abnormal rates of global warming, which is dangerous for plants and animals. (1)

5. Improved power

Your car's power and overall engine efficiency will increase exponentially if you use newer and more efficient spark plugs. It's practical, try using branded spark plugs and you'll notice faster engine response when driving.

Ideally, spark plugs do not increase power; they just restore it to the best burning level. The car will run like new, with optimal acceleration and fuel efficiency. (2)
