10 Best Spark Plugs for Better Performance and Gas Mileage

Spark plugs are associated with the ignition system of a vehicle. They create the electric spark which ignites the air and fuel mixture in the internal combustion chamber of the engine. Without this spark, there would be no combustion in the chamber. Then you wouldn’t be able to drive your vehicle because the engine cannot generate any power to move the wheels.\

For this reason, the spark plugs are vital components of the engine’s performance. They always need to be fully functional to operate the vehicle.

Engines have multiple cylinders where the combustion process takes place. Each cylinder has its own spark plug for the ignition of its air and fuel mixture. Sometimes there are situations where one spark plug might fail, resulting in that cylinder failing to ignite.

This doesn’t necessarily mean the entire vehicle will stop working, but it will certainly reduce the amount of engine power that is generated. You’ll notice things like weaker acceleration and engine stalling as you’re driving. That is why you need to make sure that all your spark plugs are working properly.

When most people shop for spark plugs, they assume that all spark plugs are the same. The truth is there are different types of spark plugs available. You can always tell the quality of a spark plug by its price and the material it is made from. This will go a long way in getting the best performance you can out of your engine.

Not only that, but it will also give you more gas mileage too. Remember that when the combustion goes well, the engine has an easier time of generating power. This means less demand for more power and fuel. So, choose spark plugs that will assist in giving your vehicle the best combustion possible.

Top 10 Best Spark Plugs

There are copper spark plugs, single platinum spark plugs, double platinum spark plugs, and iridium spark plugs. You might assume that iridium and double platinum are always the better choices, but not in all situations. The type of engine in your car and the manufacturer of the spark plugs are also things to consider.

Below are the top 10 spark plugs for providing better engine performance and gas mileage in a car.

1) Autolite HT15 Platinum High Thread Spark Plug

This Autolite spark plug model is used a lot in Ford vehicles. Its construction is solid steel with a tip made of platinum.
