Spark plugs are very essential parts of V6 engines. Without spark plugs, internal combustion engines will not work. Also, most people are curious about the question of how many spark plugs are in a V6 engine. Here you can find detailed information about this question. But also, you can get the simple answer that you need immediately.
Simple Answer: 6 Spark Plugs in V6 Engines Mostly
So, as you understand that the number of cylinders is equal to the number of spark plugs. Because each cylinder needs one spark plug to ignite the air-fuel mixture inside the cylinder. This is the general number of V6 engines.
But as you see above, said that “mostly”. Why? Because there are exceptions to consider. There are two sparks plug V6 engines available in the market. So, these engines shave two spark plugs for each engine cylinder that they have. So this means some V6 engines have 12 spark plugs!
Why Some V6 Engines Have 12 Spark Plugs?
There is a very big advantage of the two spark plugs in one cylinder. The ignition will be much more efficient and burnşing of the air-fuel mixture become easier. So, the engine will expense much less air-fuel mixture in general. If you want to create a high-power engine, you can use two spark plugs. Because sending the same amount of fuel and you will get much more better and accurate ignitions.
But also there is a very big downside of the 12 spark plugs or 2 spark plugs for each cylinder. The most important disadvantage is increased maintenance costs. Because the ignition and electrical system of these systems is generally much more complex than the normal applications.
So, at the expense of high maintenance costs, you will obtain much more power.
What are the Examples of These Engines?
In the market, we can give two important engines that are available in the market.
- 2004 Mercedes CLK 240: This is a very good high-end powerful car that has a V6 engine with 12 spark plugs. They used the technology that we explained about the V6 engines.
- 2004 Chrysler Crossfire: Also in some American cars, they use twin spark plug technology. This is a car that used a V6 engine with 12 spark plugs.
- 2006 Mercedes S350: Also this one is the highest class of Mercedes cars. So, the high price o maintenance costs will not be a general problem for these people. And they added two spark plug technology to the V6 engine that this car has.
Most of the other V6 engines generally have 6 spark plugs.
So, How Does the Spark Plug Work?
At this point, this is the question that comes to mind. Because people are curious about why increasing the number of spark plugs makes the maintenance costs higher. To understand it, we need to understand how that system works.
First of all, yes the duty of the spark plug in a car is very simple. The only duty is to ignite the gasoline inside the cylinder. Buıy they need to do it in accurate and exact time. To do it, we need a distributor system.
A distributor system is a system that provides the ignition of the spark plugs in the required order and accuracy. It makes this with the motion that comes from the engine belt. All the spark plug cables are connected to that distributor system.
And also the distributor system is connected to a car battery for electricity supply. And if we increase the number of spark plugs, these systems will become more complex as you expect.
For twin spark plug systems, the ignition of the spark plugs is generally adjusted in a specific way. In general, they do not ignite at the same time. So, the distributor systems and the electrical systems of these applications can be somewhat different and complex. And the maintenance of these systems becomes more complex than ordinary applications.
How to Count the Spark Plugs in an Engine?
This is a very simple thing. Once you open the car hood, you will see the V6 engine standing in there. And you can see that there are black plugs that are attached to the top of the cylinders and engine head. The number of these black plugs is the number of spark plugs.
Or you can also look at the distributor system directly. Count the number of distributor plugs that will give you the number of spark plugs in an engine.
So, it is very simple to define it correctly.
Even Some V6 Engines Have 24 Spark Plugs!
Yes! This means every engine cylinders have 4 spark plugs! So this is a very different application if we can see. The 2013 Dodge Charger has 4 spark plugs per cylinder in the V6 engine. And this provides excellent engine performance. But in terms of the maintenance… We do not know.
How Much Does it Cost the Replace a V6 Spark Plug?
Replacement costs of spark plugs do not change according to the number of cylinders. The spark plugs are individual parts that we need to consider according to this.
The most important parameter that defines the spark plug price is the OEM or aftermarket part. Aftermarket parts are generally cheaper. But their lifespan and performance şs not generally the same with the OEM parts.
Another important parameter is the brand and model of the car. In general, it defines the general labor costs. Because dealing with Laöborgihini is not the same as dealing with Nissan Altima. So, if you have a high-end car, you will probably pay much more.
By considering all these parameters, we can say that the price range of replacement of V6 spark plugs can change between $150-$500 including all costs.
Last Words on How Many Spark Plugs in a V6
