Spark plugs not given the kind of attention they deserve. Some might ignore its capacities. But truth be told, without appropriately working spark plugs, your vehicle, without a doubt, wouldn’t have the option to run by any means.
Vehicles run because of internal combustion, where the fuel burns to release potential energy converted into kinetic energy by the mechanical parts.
These little things known as the spark plug provides that little spark that ignites the fuel and gets the process going.
What are the Benefits of Changing Spark Plugs?
Sparks plugs go through wear and tear over time, and it starts to affect their performance. Replacement instantly restores the lost power, which optimizes the vehicle’s performance.
The benefits of changing spark plugs are:
- Increases efficiency and performance of the engine.
- Improves cold starting.
- Smoother engine.
- Improved ignition and starting characteristics.
- Improved acceleration.
- Better fuel economy.
If you are here to know more about the benefits of changing spark plugs, you are at the right place.
Increases Efficiency and Performance of the Engine
A worn-out spark plug often results in engine misfiring. There can be other issues like a buck, stall, rough running, or slow starting.
Getting a new plug will improve the engine’s performance and help it run at maximum capability.
Improves Cold Starting
Replacing the old spark plug also decreases cold starts, a typical winter problem. It is one of the significant advantages of changing spark plugs.
Dirty or old spark plugs require a comparatively higher voltage to generate a powerful enough spark for the engine to get going.
Continuous combustions mean your engine is running smoothly. It results in your vehicle running the way it should with zero hassle. Do you see where I’m going with it?
The continuous combustion will be ensured when the spark plug will produce enough charge continuously. Getting a new spark plug will provide that.
Improved Ignition and Starting Characteristics
The efficiency of the spark plug matters a lot because the better the plug performs, the lower the ignition voltage.
Therefore, another of the benefits of replacing spark plugs and coils is an overall improvement in starting the vehicle.
Here is something to remember when you are dealing in this area. It isn’t just about the spark plug. It’s the wires too.
The benefits of replacing spark plugs and wires include improved current flow through the system, leading to improved acceleration.
Better Fuel Economy
Regardless of how low your car is designed to consume, a worn-out spark plug reduces the fuel economy up to 30%.
As a driver, you must understand the importance of efficient fuel consumption. With a new spark plug, you can restore the original fuel efficiency of your vehicle.
What Heat Range Spark Plug Should I Use?
Spark plugs have different heat ranges because, in addition to generating a spark for ignition, it is in control of removing the heat from the combustion chamber.
Let’s have a deeper look into the mechanism. A spark plugs channels the heat through the insulator material and the metal housing to dissipate the heat. That heat then travels to the cylinder head, where the cooling system can take over the rest of the job.
So, the real question is, what range should you choose?
I recommend going for the factory recommended heat range. With the addition of every 75-100hp to the engine, you might go to the next colder step. The DENSO heat range moves up as the spark plug gets colder. An iridium power plug with a range of 16 is the hottest, whereas 34 is the coldest.
DENSO ranges: 20, 22, 24, 27, 31, 34
Now, you need to understand the range itself. To keep it simple, look at it this way.
The colder the spark plug is, the more heat it’ll be able to channel out. In terms of performance, a colder plug is better able and necessary to handle the high temperature caused by the forced induction, High RPM, and higher compression ratio.
With all these benefits of a colder one, it seems like the way to go but remember every vehicle is different and essential for the plug to reach its ‘self-cleaning temperature.
It is necessary to heat up to a particular range to prevent the spark and plug from fouling out
Now let’s talk about a plug that is ‘too hot. The most apparent drawback of the plug with a high-temperature range is overheating, leading to detonation, power loss, pre-ignition, and even permanent damage to the engine.
