You might not give spark plugs a second thought, although they play a critical role in the operation of your vehicle. In fact, your car would most likely not be able to function at all if the spark plugs were not in good operating order.
Initially, you might think all V8 engines are thought to contain eight spark plugs. However, the quantity varies depending on the type of V8 engine used.
To answer the issue of how many spark plugs are in a V8 engine, you must first determine the type of V8 engine in your car.
In this article, our car experts will take a closer look at v8 engines, how many spark plugs are in a v8 and more.
What Is a V8 Engine?
V8 engines are known for having more power and acceleration. That is why V8 engines are said to be suitable for most sports cars.
They can deliver a lot of consistent power if you use your car mostly for hauling and towing.
The driver can feel the engine’s immense vigor and power by softly pressing on the accelerator, which is just one of the numerous reasons to get into a V8-powered vehicle and savor a refined and luxury ride with improved speed and efficiency.
How Many Spark Plugs in a V8 Engine
There are eight spark plugs in a V8 engine, one for each cylinder. However, several manufacturers in the United States and Europe use twin-spark or dual-ignition technology.
In such circumstances, the V8 motor has more than eight spark plugs. We can count the number of spark plug wires on our V8 engine to see the number of spark plugs.
There are eight spark plugs in the motor; hence there are eight wires.
Although most engines can get by with just one spark plug, some automakers have begun constructing engines with two spark plugs per cylinder.
Twin spark or dual spark engines are the names given to these engines.
A table displaying the number of spark plugs required by various V8 automobiles and trucks can be seen below. The most popular engines that use 16 spark plugs are those made by Mercedes and Chrysler.

How V8 Engines Work
In this video, you will learn how V8 engines function. Before moving on to the 3D-printed Chevy Camaro lS3 V8 details, you will learn first about the basics.
To start, V8 engines derive their name from the fact that they have a V-shaped cylinder block, which is 90 degrees in this case, and eight cylinders.
The numbering begins on the right with the front-most piston and progresses backward.
This engine follows the same basic principles as any other four-stroke gasoline engine. As the piston moves lower, it draws in air and fuel, then compresses that air and fuel as it rises upward.
The piston is then forced downward by a spark plug, which ignites the air-fuel mixture and ignites the spark plug. Before the cycle restarts, the piston pushes out the exhaust fumes on its way back up.
Since this is a V8 engine, the cycle is happening in eight different cylinders at different times. Instead of multiple cylinders firing simultaneously, you want them to be spread out, so that power delivery is smooth for this Chevy V8. Watch the video to learn more about it!

Difference Between V8 and V6
What are the differences between a V6 and V8 engine, aside from the number of cylinders? We’ll go through the distinctions between them and some of the benefits of each so you can decide which is best for you.
The V6 engine is lightweight yet powerful. V6 engines have been around since the invention of the internal combustion engine.
Despite its simplicity, it is less expensive to manufacture and weighs less. V6 engines produce more power and run more smoothly than four-cylinder engines.
The V8 engine is characterized by three words: timeless, loud, and powerful. The V8 has become more than just the engine that powers various automobiles throughout the years for various reasons; it has reached iconic status in its own right. Many drivers associate the V8 engine with America.
Advantages of Using More Spark Plugs in a V8 Engine
In a HEMI V8 engine, each cylinder has two spark plugs. Instead of wires, the HEMI V8 motor uses ignition coils.
Each ignition coil powers two spark plugs. As a result, each cylinder has two spark plugs, for a total of 16 spark plugs.
V8 engines using dual ignition technology feature two spark plugs for each cylinder. This increases horsepower while also lowering pollution. In regular driving situations, this also means higher fuel economy.
How to Change Spark Plugs in a V8 Engine
In this video, you will learn how to change the spark plugs on a supercharged five-liter v8 l405 Land Rover. Here, the expert recommended that the spark plugs be changed every 90 to 105 miles with normal driving.
The Land Rover that was used to show how to change spark plugs in the video has traveled 35,000 miles.
The expert changed the spark plugs at 35 because they are so easy to do. Aside from that, he mentioned how spark plugs in a v8 engine are good because they give you fuel economy and efficient performance. Most importantly, part of the maintenance of vehicles is changing the spark plug.
Remember to put your safety first at all times. Then unscrew the spark plug, remove the spark plug wire, and remove the coil on the plug.
Finally, replace the spark plugs. This will be covered in greater depth in the video. So, go ahead and watch!
Things to Keep in Mind Before Changing Spark Plugs in a V8 Engine
In any car, changing the spark plugs is as simple as removing the spark plug wire or ignition coil, removing the spark plugs, and replacing them with new ones. Modern engines will necessitate a different approach.
The most key point to remember is to let the engine cool completely before starting it. Because aluminum is more sensitive than steel, changing or removing the spark plugs must be done with utmost caution.
It’s critical to let the engine cool down before replacing the spark plugs if your V8 engine has aluminum heads.
Before installing each spark plug, double-check the gap. To establish the proper gap, consult the service manual.
Applying the proper torque when fitting the spark plugs is crucial. Overtightening the spark plugs is a common mistake that can damage or deform the aluminum head.
Always use a torque wrench and follow the torque specifications in the owner’s manual.

Tools Needed When Changing Spark Plugs
Whether you’re a vehicle enthusiast or just want to avoid car trouble, replacing spark plugs is a necessary element of basic maintenance. Simply said, ignoring your car’s plugs is a disaster in the making.
Remember to double-check your owner’s manual for the recommendation to replace it. The following are some tools that you can use.

Frequently Asked Questions (FAQs):
What is the number of coils in a V8?
An ignition coil is a device that provides voltage to the spark plugs in any engine. Any engine with four, six, or eight cylinders will have an ignition coil, regardless of how ancient or large it is.
A V8 engine may contain 1, 4, or 8 coils, depending on the manufacturer and year of production. Almost all older autos had a single-coil before the 1990s. Newer vehicle designs, on the other hand, are different.
Is V8 better than V10?
You might think that the higher the V-number, the better the sound quality. The right answer lies in this explanation of the V8 vs. V10 and V12 engines.
Sound quality is usually determined by its frequency, with high-frequency sounds being thinner in quality and low-frequency sounds being thicker and fuller.
This helps to explain why a V8 engine sounds so much better.
An engine must displace a greater gasoline amount; the more fuel displaced, the fuller the sound becomes.
It is a well-known truth that V10 and V12 engines have more cylinders – just stating the obvious – but it is also a reality that the cylinders in a V8 engine are larger.
What mileage do you need to change your spark plugs?
Spark plugs are replaced because they wear out, become dirty, and fail over time. When should you change your spark plugs?
Spark plugs are divided into two categories: conventional and long-life. Spark plugs are replaced every 30,000-50,000 miles on a standard vehicle.
Meanwhile, long-life spark plugs should be replaced every 60,000 to 150,000 miles depending on the vehicle.
The owner’s manual will provide the suggested replacement intervals. If there is an issue with the spark plugs, they may need to be replaced sooner.
Is it always necessary to gap spark plugs?
It’s vital to check the space between spark plugs while replacing them because it affects engine performance.
The gap is the distance between the center and side electrodes, which is set such that arcing happens at the correct voltage, igniting the fuel and producing the combustion that allows the engine to run.
Spark plugs used to need to be gapped; however, they are frequently pre-gapped these days. Double-check that the gap is set correctly to the vehicle’s suggested setting when installing spark plugs.
Why do some engines have two spark plugs for each cylinder?
Your engine will be more reliable, produce more power, and burn gasoline more evenly with two spark plugs per cylinder. When the three are combined, you get an ultra-reliable engine.
First and foremost, your engine’s two spark plugs per cylinder are due to its dependability. If you face a problem such as a spark plug fail, the other spark plugs will continue to fire on all cylinders when a spark plug fails.
Another significant advantage of having two spark plugs per engine is increased power. A “dual-flame front” is created when two spark plugs in a cylinder fire simultaneously.
Instead of igniting from a single spot in the cylinder, your fuel-air mixture ignites from two different sites on opposite sides of the cylinder.
In a dual spark plug setup, combustion is the final key aspect. The fuel-air combination burns top-down from the center outward when each cylinder has only one spark plug.
However, when two spark plugs are placed on opposite sides of the cylinder, the fuel-air mixture burns from the cylinder’s edges inward.
To summarize, an aviation engine with two spark plugs per cylinder is more dependable, produces more power, and burns fuel more evenly. When all three are merged, you get an extremely dependable engine.
Hopefully, you finally know how many spark plugs a V8 has. Most V8 engines will have eight spark plugs or one for each cylinder.
Some modern engines, such as those made by Mercedes or Dodge, contain two spark plugs per cylinder, for a total of 16 spark plugs.
It is preferable to replace all of your spark plugs at once rather than one or a couple at a time. It’s possible that if you don’t replace all of your spark plugs simultaneously, your engine will run rough. Be mindful and stay safe!
