Things to Consider Before Buying Spark Plugs for Horsepower
If you own a car or know the basics of a car engine, you already know the benefits of using spark plugs to increase the engine’s efficiency. And when it comes to getting the total horsepower from the engine, you should use the right spark plug. You’ll find so many spark plugs that are readily available in the market.
Your nearest auto parts stores can provide you with many types of spark plugs. But, when it comes to choosing the best one, you require industry expertise or product-related knowledge.
That is why we are here to provide you with all the necessary information about the factors you should consider before buying a spark plug. You should look for the following vital things before purchasing a spark plug for horsepower.
It is common sense that there are many types of vehicles that come in different sizes. So, different individuals may have different cars with a variety of sizes. Therefore, when it comes to buying a spark plug, you should check your vehicle size to find the most compatible spark plug.
You can read the owner’s manual for checking the compatibility issues and find the right sized spark plug for your vehicle type.
The next thing you should consider is the material of the spark plugs. You must go for a spark plug that can fulfill your needs. If you are using an older model vehicle, we recommend a copper spark plug for you.
Because the ignition will be done in those vehicles within a low voltage range, on the contrary, if you have a modern car, you should go for platinum or iridium spark plugs as they are so suitable for engines without distributors.
In a general sense, platinum spark plugs are best for delivering excellent performance. Iridium is also a good material, but it is a little bit expensive. Another rule of thumb is you should follow the recommendations of the vehicle’s manufacturer.
The heat range of the spark plug is also an essential factor which you should consider with utmost care. If the spark plug can insulate heat, it can be specified as hot. On the other hand, some spark plugs are good at conducting heat out of the tip to lower the temperature. You should always check the heat range carefully to buy the right product for your vehicle.
The next factor you should check carefully is the gap style of the tool. In a general sense, spark plugs are specifically designed to have a gap between the electrodes. In most of the cases, it can be done by using a gapper.
Now, some spark plugs come in a pre-gapped condition that doesn’t require any further gapping. You should try to choose this type of spark plug so that you don’t have to take any extra stress for gaping the tool.
The last but not the least essential considerable factor is the price of the spark plug tool. You already know that the right quality products may cost you some extra penny. But, you should also consider your budget when buying the device. However, you should never sacrifice the product quality for some extra bucks.
Frequently Asked Questions (FAQs)
What are the best spark plugs for horsepower?
Answer: Some spark plugs can bring back more horsepower in the engine. Without any doubt, iridium tipped spark plugs can give you the optimum performance when it comes to gaining the horsepower.
However, you should keep one thing in mind that spark plugs are not a standalone item that can increase the horsepower. It’s the engine that does the most of the part. But, a new iridium spark plug can certainly bring back some strength, which is lost over time due to the old spark plugs.
Can spark plugs affect engine performance?
Answer: Yes, of course. The engine performance of your vehicle somewhat depends on the type of spark plug you are using right now. If you are using a fouled spark plug or it has a lot of carbon build-up, they will be unable to completely burn the fuels which are injected in the engine cylinders.
It is one of the biggest reasons why some engines are using more fuels. That is why you should go for a good quality spark plug to get the maximum engine and fuel efficiency.
Can spark plugs make your car faster?
Answer: In a general sense, no, spark plugs will not make your car faster. If you want to increase the car speed, you may need to modify the car engine or gear ratios to handle extra speed. However, when it comes to a spark plug, it can create a stable spark which will help the engine to burn the fuel efficiently.
If you are a car owner or a professional mechanic, you need the best spark plug to improve the efficiency and regain the horsepower of your car engine. Now that you already know all the essential factors that you should consider before buying a spark plug for your engine, you can easily choose the best product.
