Spark plugs are responsible for the electric spark that ignites the air-fuel mixture in the combustion chamber by carrying a high voltage current from the ignition coil. As your spark plugs start to wear out, you need to replace them with fresh spark plugs.
Note: A spark plug replacement is usually accompanied by getting new wires. A worn spark plug wire often fails to properly transmit the high voltage current from the ignition coil to the cylinder head.
Spark plug replacement not only yields higher results for your vehicle but also offers several other benefits. These include:
1. Optimum Functioning Of The Combustion Engine
Spark plugs are responsible for the combustion of the air-fuel mixture inside the combustion chamber. An old spark plug can mess with the car’s gas mileage and require more power to keep the vehicle running.
Properly functioning spark plugs positively affect your car’s performance. Getting a new set routinely ensures that your engine stays in good shape, and you save hundreds on repair in the long run.
2. Increased Fuel Efficiency
The National Institute of Automotive Service Excellence reported that an old spark plug or faulty plug could lead to engine misfires, resulting in a 30% lower fuel economy for your car. A worn spark plug will also increase the drivers’ costs. These included maintenance, fuel refills, etc.
Without a strong enough spark to fully ignite the air-fuel mixture, the engine churns more fuel to start the combustion. Spark plugs are bound to get less efficient with time. But changing them can prevent this and restore your car’s fuel efficiency, fuel economy, and gas mileage to its original state!
3. Smooth Start-Up Performance
As your spark plugs age, they start affecting your car’s performance. An old spark plug can cause rough idling, engine idling, and poor acceleration.
You’ll also notice that worn spark plugs have a wider spark plug gap due to wear. This, in turn, interrupts the consistent combustion system leading to rough idling, poor acceleration, and engine misfire.
But all of this goes away when you get a new spark plug set!
4. Lower Carbon Emission
Worn spark plugs put a lot of pressure on your engine. Since new spark plugs should be appropriately gapped at installation, they’ll operate at optimum power. This results not only in improved fuel economy but also in reduced harmful emissions!
In fact, the Environmental Protection Agency reports that regular car maintenance (especially replacing a worn-out spark plug) can substantially reduce your car’s harmful emissions.
5. Improved Horsepower
Finally, new spark plugs can greatly improve your car’s horsepower and overall engine performance. When you change your worn-out spark plug with fresh spark plugs, you’ll notice a much faster engine response when driving.
While spark plugs don’t technically increase your engine’s horsepower, they bring it back to its optimal combustion level. In simple words, your car will run as if it’s new with optimum acceleration control and improved fuel economy!
