The greatest benefit of changing your spark plugs is that your engine will run better, provide you with improved gas mileage, and may reduce the pollution from the vehicle.
What are the benefits of new spark plugs?
New spark plugs provide a lot of other performance benefits as well: Consistent production of optimal combustion. Fully functioning spark plugs help support a fully functioning combustion system. Get this operating successfully, and a lot of performance issues you’re experiencing could be a distant memory. Better fuel economy.
What happens when you replace spark plugs?
When you replace your spark plugs, you may notice that your car feels more responsive. Changing spark plugs is a key part of keeping your engine in good working order.

How does a spark plug work?
A spark plug does exactly what its name suggests: It’s responsible for creating the spark that an internal combustion engine needs to start and run. When electrical voltage is sent to a spark plug, that electricity arcs the small gap between the two electrodes at the firing end, igniting the compressed fuel-air mixture inside the cylinder.
Do spark plugs increase horsepower?
A new spark plug will also have a significant impact on the car’s horsepower. Spark plugs will not actually increase the car’s horsepower, but they do bring the car’s system to its optimal combustion state and thus improve the current flowing through the wires in the system.
Do spark plugs affect fuel economy?
If spark plugs are misfiring or performing poorly, your gas mileage will be affected. Spark plugs are responsible for sparking engine combustion. They can’t do that if they aren’t working efficiently. Bad oxygen sensors and air filters can reduce gas mileage by as much as 20%!
Can bad spark plugs affect gas mileage?
The National Institute for Automotive Service Excellence indicates that bad spark plugs can decrease fuel economy by up to 30%, and can cost drivers up to about 94 cents per gallon at today’s prices. 1 If a car’s gas mileage suddenly drops, there’s a good chance it’s because of misfiring spark plugs. 8. Check the Alignment
Do new spark plugs burn more fuel?
However, any new spark plug that is gapped correctly will burn the fuel/air mixture with great fuel efficiency. Your vehicle/engine’s fuel economy relies on much more than just the spark plugs to burn the fuel/air mixture efficiently. Does OEM make a difference when replacing spark plugs?
How much spark plug gap should I increase?
If you drive your car normally and tune the engine regularly, you can increase the spark plug gap by about 0.010″ for better performance and better fuel economy. However, if you drive at full throttle most of the time, you should reduce the gap by about 0.010″ for better performance.
How much does it cost to replace spark plugs?
The National Institute for Automotive Service Excellence just recently revealed that old and bad plugs can decrease a vehicle’s fuel economy by as much as 30%. At current prices, that can cost drivers as much as 94 cents per gallon. Suffice to say, it is essential to replace your spark plugs regularly.
How important is a spark plug?
Spark plugs emit a bolt of electricity across a small gap igniting the fuel and air mixture that puts the pistons in motion and gets your vehicle up and running. It’s a crucial job that spark plugs have because if they’re worn out they won’t emit a spark and start your engine or can even cause significant damage.
