When it comes to car engines, there are a lot of things that people don’t know. For example, how many spark plugs in a v8? How do you change the air filter on your car? If you’re not sure how to answer those questions, or if you just want to learn more about car engines in general, then keep reading. In this blog post, we’ll explain everything you need to know about car engines and how they work. We’ll also cover some of the most common myths and misconceptions about car engines. So whether you’re a complete beginner or an experienced mechanic, read on for all the information you need!
What is a Spark Plug of Engine?
A spark plug is a device that helps deliver an electric current to the engine’s spark plugs. The spark plugs then ignite the air/fuel mixture in the cylinders, which powers the car.
Spark plugs are typically made of metal, such as copper, iron, or steel. Some spark plugs also have a ceramic core.
How to Know if Your V8 Is a Twin Spark Engine?
The easiest way to check if your gasoline engine has dual ignition technology is to check your owner’s manual.
Alternatively, you can visually inspect your car’s engine. That’s it:
Open your hood and remove your hood. Just make sure your car has been off for a while so your engine doesn’t get hot.
Count each spark plug wire (usually the blue, red, or black wire) next to each cylinder head. Each spark plug has one spark plug wire.
If you can’t see the spark plug leads now, your V8 engine is using a coil pack. They are located on top of the V8 engine, away from the crankshaft, and each spark plug has a coil pack.
So if you count more than 8 leads or coil sets, you have a twin spark engine with 16 spark plugs in your V8 engine.

How to Replace Spark Plugs in a V8 Engine
If your car has a V8 engine, then it likely has eight spark plugs. To replace them, you’ll need to locate the spark plug wires and remove them from the plugs. Once the wires are removed, you can unscrew the old plugs and screw in the new ones. Be sure to use the correct size and type of spark plug for your car.
Spark Plug Removal:
To be able to remove the old spark plugs from the engine, you need to be able to loosen the spark plugs from the cylinder and pull them out of the engine.
The good news is that they make tools specifically designed for spark plug removal, allowing you to insert one end of the tool into the cylinder wall to be able to loosen the spark plug. Then, a magnet is built into the base of the tool, so you can remove the spark plug from the engine cylinder by using the magnet to pull the spark plug up and out of the cylinder wall.
After removing the old spark plug, you can now reinstall the new spark plug. Some spark plugs require an anti-seize compound on the spark plug threads to make it easier to remove next time, but some spark plugs may already have some application applied, or may not require application when installed.
Spark Plug Gap:
The spark plug gap is the distance between the end of the spark plug electrode and the ground strap or metal shell that helps complete the electrical circuit. An incorrectly gapped spark plug can lead to engine misfire, poor fuel economy, and increased emissions.
Install Your New Spark Plugs:
Once you have the new spark plugs, it’s time to install them.
Do not over-tighten the spark plugs, as this can damage the threading in the cylinder head and cause problems down the road.
Tighten the spark plug until it is snug, then use a torque wrench to tighten it to the manufacturer-specified torque. This is usually between 13 and 18-foot pounds, but always check your owner’s manual or service manual to be sure.
Finally, once the spark plug is tight, reconnect the spark plug wire by snapping it onto the terminal of the spark plug. Be sure that the boot is fully seated on the spark plug before moving on to the next one.

FAQs About Spark Plugs V8 Engine
Do Spark Plugs Have A Shelf Life?
Spark plugs can’t and won’t last forever for several reasons we’ll discuss later. When spark plugs and their components interact with various substances such as air, fuel, liquid mixtures, etc., deposits begin to form on them.
Can A Spark Plug Unscrew Itself?
While a spark plug can unscrew itself, it’s not a common occurrence. If you’re concerned about this happening, you can use a little anti-seize compound on the threads to help keep them in place.
What Causes Weak Spark On The Spark Plug?
There are a few things that can cause a weak spark on the spark plug, such as deposits on the electrode, an incorrect gap setting, or worn-out spark plug wires.
Can You Over-Tighten Spark Plugs?
You can over-tighten spark plugs, which can damage the threading in the cylinder head and cause problems down the road. To avoid this, tighten the spark plug until it is snug, then use a torque wrench to tighten it to the manufacturer-specified torque. This is usually between 13 and 18-foot pounds, but always check your owner’s manual or service manual to be sure.
Do Spark Plug Wires Go Bad With Age?
Spark plug wires can go bad with age, and when they do, they can cause all sorts of problems like engine misfires, poor fuel economy, and increased emissions. If you suspect that your spark plug wires are bad, it’s best to replace them as soon as possible.
Can I Use A Different Spark Plug?
You can use a different spark plug, but it’s important to consult your owner’s manual or service manual first to be sure that you’re using the correct type of spark plug for your engine.
Do I Need A Torque Wrench For Spark Plugs?
If you’re going to be changing your own spark plugs, it’s a good idea to have a torque wrench on hand. This will help you to avoid over-tightening the spark plugs, which can damage the threading in the cylinder head.
Can You Use A Normal Socket For Spark Plugs?
Yes, you can use a normal socket for spark plugs, but it’s important to make sure that the socket is the correct size. If the socket is too large or too small, it could damage the spark plug.
