Motorcraft Spark Plug

View on Amazon

Are you on the lookout for the best spark plugs for Ford F150 Ecoboost? Is finding one becoming a hassle?

Why not go for something that is recommended by Ford itself? 

Yes. The SP 534 spark plug is a direct recommendation by Ford and works well as replacement plugs for the original.

Better yet, they can not only replace the coil-on-plug ignition system that is found in new vehicles but can also replace the old distributor-equipped system found in cars.

Multipurpose, nice!

Therefore, it is multipurpose. Thus, making it versatile and compatible with many Ford cars. Apart from Ford, it also fits many models of Mercury and Lincoln cars.

Now, you don’t need to worry about fuel consumption:

Additionally, it provides a perfect balance of performance and fuel-efficiency.

Gone are the days when you saw an increase in fuel consumption after installing new spark plugs.

SP 534/ SP 580 will relieve you of that worry too.

Installation is a piece of cake!

Unlike other spark plugs, this one comes pre-gapped at 0.035”. At least, that made our day. Setting the gap is one thing we hardly get right to the last degree.

So, this was a plus point. All you need to do is check the setting before you start the installation and you are good to go. However, to install it, you will need a 5/8socket.

To get consistent and high performance, we would recommend checking the spark plug after every 60,000 miles.

At this point, they would be needing replacement. Even if everything seems okay, go ahead and replace them. After all, it has its life, doesn’t it?

Once you replace the OEM plugs with these, you can say bye-bye to misfire and sparks.

Moreover, the chrome exterior promises better conductivity and allows current to pass better as compared to other materials.

Being made of dense iridium ensures it is durable and will last long. Therefore, you can rely on it!

As light as a breeze:

It weighs only 1.6 ounces. Other dimensions include a height of 9.398 cm, length of 2.54 cm, and width of 2.54 cm.

So, check if it is compatible with your vehicle or not in the manual.

The only downside to it is that if you are looking to customize the gap, it is not possible. You can’t change the gap specification.

Hence, if you are looking for something like 0.029”, this is going to be of no use to you.

Pros
  • Pre-gapped
  • Chrome exterior
  • Extended durability
  • Easy installation
  • Ford recommended
  • Lightweight
Cons
  • The gap cannot be customized

2. Bosch 9616 Double Iridium Spark Plug

Bosch 9616 Spark Plug

Copper plugs do well for your Ford, no arguing with that statement. But, if you just don’t want to settle for the average, go for iridium spark plugs.

Better yet, double iridium will promise better performance!

Iridium is the best you can get! It’s the newest technology and gives the highest performance when it comes to sparking plugs.

Therefore, the Bosch 9616 double iridium plug might just be the one for you.

The reason being, the firing pin is made of double iridium and comes with a ground inlay.

Together, they are engineered in such a way to boost the performance up to 4 times when compared with the normal copper plugs.

4 times, let that sink in!

Both of these give the car the performance boost it needs. Working together, they let current flow easily and quickly, hence firing up the car much sooner than the others.

The specifications are very precise. For instance, the firing pin is very fine, measuring only 0.6mm.

Additionally, the firing pin is welded to the base through 360-degree laser welding. As a result, breaking off or becoming loose is not a possibility.

This is the reason why it is durable and goes on when all other plugs die!

Equipped with the best OE spark plug technology, it can end up saving you fuel worth hundreds of dollars over a lifetime.

Not only this, the engine response is excellent.

The guarantee on it is the best:

You get a performance satisfaction guarantee. This means that if you are not satisfied with the performance of the plug and want to return it, you can do so within 7 years.

Interesting, isn’t it?

Moreover, it does not require any gapping.

Yes, it is true:

This is because it has a ribbed insulator design. It has been designed in a way to ensure there is no flashover. Therefore, increasing longevity.

As of now, all you need to do is open the hood and install the plug.

Anti-seize, what is that?

No more tension of applying anti-seizes. The rolled threads are encased in a nickel-plated shell.

The shell itself is corrosion-resistant and anti-seize, so no additional products are required.

The only downside we could find was that it is expensive as compared to the others.

That being said, the price does do justice to the exquisite quality and performance it provides.

Fit for:

It is vehicle-specific. But, the major brands it does with are many. For instance, Ford Escape, Buick, Chevrolet, Camaro, Malibu, Cadillac, GMC, Limited, Fusion F-150 Mustang, Lincoln Mazda Mercury, and many more.

Thus, making it versatile and highly compatible.

Pros
  • Durable
  • 4 times greater performance as compared to copper plugs
  • Laser tapered ground electrode
  • No need for gapping
  • Fits many vehicles
  • No anti-seize required

3. E3.74 Automotive Spark Plug

E3 Spark Plug

View on Amazon

With the latest technology, the E3 spark plug plays its role in reducing dangerous gas emissions. It reduces hydrocarbon by 42% and CO emissions by 58%.

Those are some figures, aren’t they?

The only catch is that these numbers work for 2 and 4 stroke engines.

Moreover, the best thing about it is that it takes the best from the traditional spark plugs.

For instance, surface gaps and cutback electrodes.

Interestingly, it has a patented design that ensures performance and fuel-efficiency by combining the new DiamondFire electrode technology. Thus, it creates a better spark.

But, how does it happen?

It has an open section which works wonders for letting the current pass through.

Moreover, this terminal end is made of nickel. Thus, it is corrosion-resistant and protects the rest of the engine too.

Offering the deepest projections on the market, this plug protrudes inside the combustion chamber.

Consequently, it offers higher ignitability as compared to others. The reason being, the spark comes near to the most robust fuel/air mixture.

Therefore, making it easy and quick for the spark to pass through.

Firstly, the combustion wave ends up leaving the spark area at higher speeds. Now, the elevated edges come into play.

They provide a sort of chimney effect, which allows the next round of combust fuel/air to come in.

It is a domino effect:

The rule is simple. Just like a domino effect, higher ignitability leads to better performance by reducing fuel consumption.

Overall, it gives a 4% to 13% improvement in fuel efficiency.

One thing that makes it stand out from the rest is that E3 plugs don’t follow the common one size fits all strategy.

They have been carefully tailored with optimized gaps to give a power increase. Talking in numbers, you get a rough 6% – 12 % increase in total.

Edge to edge spark is the new thing:

Undoubtedly, it is the best way for a spark to go ahead. Moreover, the sharp edges initiate electron migrations.

Furthermore, these fast electrons and matter collide. As a result, the entire electrons come into play and create a plasma channel.

It makes the movement of the spark easier throughout the spark plug. This cycle continues and is the reason for the almost zero carbon footprint.

Uniquely designed, the two supporting legs on the plug allow for better heat dissipation. The middle, nickel alloy core also plays its role in heat dissipation.

It comes with a limited warranty of 5 years. You need to change and check the spark plugs after every 100,000 miles.

The only issue is that they give a sort of a jerk to the engine at times. It’s a slight one, but after every 10-15 times, the engine gives a jerk.

Pros
  • Leads to higher combustion
  • DiamondFire Technology
  • Reduced carbon emission
  • Higher fuel efficiency
  • Greater longevity
  • 5-year warranty
Cons
  • Sometimes gives a jerk

Versatility is its forte:

It can be used as a direct replacement for not only Ford but also Lincoln and Mercury. With a chrome exterior and platinum interior, it is one power plug.

Platinum has a very high melting point. Therefore, it provides high resistance to erosion and keeps the engine safe.

Additionally, it has a gap of 0.054” when it comes out of the box. Due to high performance, you will need to get the plugs serviced at 60,000 miles and then 100,000 miles.

There is no more tension of misfires or any acceleration issues when you buy this plug.

The only downside to it is that it comes as a standalone plug. There is no installation hardware or complete kit.

Pros
  • Better fuel consumption as compared to the others
  • Perfect OEM fit for Ford
  • Versatile 
  • Erosion resistant because of the high melting point of the platinum core
  • No more misfire

View on Amazon

Who hasn’t heard of NGK? It is a big brand that has made a huge name in a little time.

NGK # 6509 is specially designed for people who value performance over anything else.

Got your attention, haven’t we?

The center electrode is made of fine wire iridium. Therefore, the sparks are consistent and the combustion cycle does not break.

As a result, they last longer and are durable. Best of all, the spark is consistent and does not go out. Hence, there are no misfires or jerks.

When compared to the platinum-centered spark plugs by Motorcraft reviewed above, we can see both have a very high melting point.

But, iridium takes the lead!

The iridium alloy has a melting point of 2,466 degrees Celsius. Seems almost impossible to melt, right?

Because of this, all the high-performance, top-of-the-line vehicles prefer iridium over the other materials.

So, it works for all the engines of today. After all, the engines require more power and torque when compared to the ones 50 years ago.

The exterior plating is made of trivalent metal. Thus, the plug exhibits anti-seize and anti-corrosion properties.

Higher longevity: a dream come true!

If you look closely, the insulator nose is longer than normal. Therefore, the structure limits fouling.

As there is less built-up of unwanted debris and dirt, the life of the spark plug is increased in the long run.

The trick for good performance lies in the life of the flame and how long does it expand.

For this, the electrode shape is tapered cut and made specially keeping in mind the nature of the flame. It encourages quicker flame expansion.

The flame travels faster and reaches the air/fuel mixture sooner.

Additionally, the plugs are pre-gapped and you don’t need to spend precious time trying to get the gap right.

Consequently, it makes the installation process easier. Lastly, it comes in a pack of 6.

The only downside is that the check engine light comes on very frequently. Yes, that is a hassle.

Once you switch the engine off and on again, it goes off and there is no issue.

You can get free shipping if you are living in the USA or the areas nearby.

Pros
  • Iridium center promises higher durability
  • High melting point ensures longevity
  • Anti-corrosion
  • Anti-seizing
  • Versatile
Cons
  • Check engine light comes on

Furthermore, chrome material that is used in the making of the exterior of the plugs also enhances the power and potential of the engine.

So, now it’s up to you which one you want to choose.

Weight - Compact and Easy to Handle

These tools are lighter in weight that are quite compact in shape and size. You can easily handle them and replace them manually. So, choose the one that is lighter in weight and does not give you a tough time.

Heat Capability - How does it control?

These tools tend to tolerate the high temperature because their major function is to produce a spark whenever you start the car.

So, you should choose the tool that has a high capacity to tolerate the heat change to prevent any kind of damage.

However, the spark plugs can also work in low or cold temperatures as vehicles might not start in harsh climates.

So, for that, you need a spark plug that can also tolerate the cold temperature and will improve the ignition.

How to Use it? - Be Aware!

You should go for the spark plug that suits your vehicle that’s the primary schema.

Hence, for most trucks or F150 Automotives, these spark plugs are considered to be flexible and adjustable enough. Plus, these tools should be easy to use, easy to plug-in, and easy to remove. 

How does it Work? - Learn!

Before purchasing this tool you should know a little bit about their working, performance, and capability.

Therefore, you must follow these steps and install the plugin the right way.

First of all, make sure you have chosen the exact type of spark plug for your vehicle that you were looking for and is suitable.

This tool should be fixed in the engine’s head. Then, the wire or the ignition coil will be mounted to the electrode tip of the engine chambers and to the plugs terminal side.

Afterward, the gasket ensures the sealing of the combustion process, which prevents the escape of pressure. You have to mount the spark plug rigidly.

When the user starts the vehicle, the ignition system of the vehicle sends an electrical current via the plug within a limited period.

Lastly, with the creation of the current, it passes through the plug and flows, through an evident spark. It jumps from one electrode to another as it is present at the tip of the spark plug.

Stay Simple, Stay Upgraded!

Tip: They do not need any maintenance, so just use it for the given lifespan and then change.

Note: Use the spark plug that matches your vehicle engine, otherwise, it might damage the engine.

Maintenance for these Plugs:

Cleaning of Spark Plugs for f150 EcoBoost

Check the plugs for any sign of wear and tear, if they wear out, you need to change or replace them as soon as possible, or else it will affect the performance of your vehicle.

However, when you remove the plugs for testing, maintenance, or repair, follow the given steps:

Grasp the boot of your plug and twist it softly about 90 degrees anti-clockwise. Move the boot and cord of the plug away from your plug.

You can also use a plug boot removal kit to remove your spark plug, if possible. Do not catch or hold your plug cords or drag them vigorously.

However, before extracting spark plugs, air-blast or brush the dirt or any debris off the sides of your plugs.

IMPORTANT NOTE:

Use a mask when you apply air to the spark plugs to shield the eyes from debris.

Moreover, use the right socket size (depth) for 1 or 2 turns if you want to loosen your spark plug.

NOTE: Allow the engine to cool to remove the plugs from the aluminum heads.

However, when you withdraw the plug, the engine heat, coupled with a plug that is already hot, will allow it to dismantle the head of the cylinder.

Then, remove each plug and put the cylinder number of each one of them in the tray. It will help you define and link the cylinder that involves some unusual circumstances.

Moreover, to decrease the risk of tracking; possibly exterior, on the tower of your plug, add dielectric grease into the boot field.

The grease, however, also facilitates a successful transfer of heat between the screw of the terminal (spark) and the boot terminal.

What you can do is that:

Use a guide for gapping when adding new plugs to ensure all the new plugs are of the right gap.

However, the plugs are mostly pre-gapped at the time of their manufacturing.

Never try to gap the plug yourself or else you may get the plug destroyed. Replace every inaccurately gapped socket with properly gapped connectors.

However, install glow or spark plugs at the right torque according to the specifications of the manufacturers.

Frequently Asked Question:
