We will also give you our recommendation for the top 3 spark plugs you can buy for your Jetta.

Let’s take a look!

What do spark plugs do exactly?

Spark plugs are an essential component of your car’s ignition system. They are responsible for providing the spark that ignites the air-fuel mixture in the cylinders. This mixture is then burned to create the energy that powers your car.

Each cylinder in your engine has a spark plug and they fire in a specific order. The firing order is usually stamped on the cylinder head or intake manifold so you can find it easily.

Spark plugs are made from a variety of materials, including copper, iridium and platinum.

Why good quality spark plugs are important

It’s important to use good quality spark plugs in your car for several reasons.

On the one hand, they create a stronger, more consistent spark. This is important because a strong spark is needed for proper combustion. If the spark is not strong enough, the air-fuel mixture may not fully ignite, which can lead to a loss of power and fuel efficiency.

Good quality spark plugs also last longer than cheap ones. This means you won’t have to replace them as often, saving you time and money in the long run.

Also, using good quality spark plugs can help prevent engine misfires. Engine misfires can cause all kinds of problems, including damage to your catalytic converter.

What to look out for when choosing spark plugs for your car

Now that we know why good quality spark plugs are important, let’s take a look at what you should keep in mind when choosing the right ones for your car.

First, you need to make sure that the spark plugs you choose are the correct size and type for your vehicle. (We’ve made this work for you with our recommendations below). If they are not the correct size or type, they may not fit or function properly.

Next, you need to consider the material from which spark plugs are made. Copper spark plugs are the most affordable, but they also wear out the fastest. Iridium and platinum spark plugs are more expensive but last much longer.

Finally, you need to decide how many spark plugs you want to buy. If you’re only replacing one or two, it might not be worth buying a whole set. However, if you are doing a complete tune-up, purchasing a set may be your best option.

A Volkswagen Jetta normally uses 4 spark plugs.

What is the correct gap for a VW Jetta spark plug?

The correct spark plug gap for a VW Jetta is 0.028 to 0.031 inches.

The correct spark plug gap is important because it ensures the spark plug fires correctly. If the gap is too large or too narrow, the spark plug may not work properly. This can lead to a loss of power and fuel efficiency and can even damage the engine.

Some spark plugs come pre-gapped, but most do not. You will need to check the spark plug gap and adjust it if necessary.

How often should you replace your VW Jetta’s spark plugs?

Typically, you should replace your VW Jetta’s spark plugs every 30,000 to 40,000 miles.

However, it’s a good idea to check your spark plugs every 20,000 miles or so to make sure they’re still in good condition. You may need to replace them more often if you drive frequently in slow traffic or in dusty or dirty conditions.

Failing to replace spark plugs can lead to all sorts of problems, including engine misfires, loss of power and poor fuel efficiency.

If you are not sure how to replace your spark plugs, consult a professional mechanic.

1. Park the car and turn off the engine.

2. Open the hood and locate the spark plugs. They are usually located near the top of the engine.

3. Use a ratchet or socket wrench to remove the spark plug wires. Some VW models have a coil pack instead of individual spark plug wires. If that’s the case, you’ll need to remove the coil pack first.

4. Inspect spark plugs for signs of wear or damage.

5. Use a spark plug opening tool to check the gap of the plugs. If the clearance is not within the correct range, you will need to adjust it.

6. Clean any dirt or debris from spark plugs and reinstall.

7. Reconnect spark plug (or coil) wires and close hood.

How to change VW spark plugs yourself

If you want to save some money, you can change your VW’s spark plugs yourself. It’s a relatively simple process that most people can do in about an hour.

You will need a few tools including a ratchet, socket and spark plug wrench. You may also need an extension cord if your spark plugs are hard to reach.

First, locate the spark plugs and unscrew them using the ratchet and socket. Be careful not to drop old spark plugs as they can be delicate. Then take out the old spark plugs and inspect them.

If they are damaged or worn out, it’s time to replace them. If they are in good condition, you can clean them and put them back.

To install the new spark plugs, screw them in by hand and then tighten them with the ratchet. Be careful not to over-tighten as this can damage the threads.

After all spark plugs are inserted, start the engine and check that it runs smoothly. If not, consult a professional mechanic.
