Choosing Quality Spark Plugs for a F150 Ecoboost

Vehicle Compatibility

If you require 2013 F150 Ecoboost spark plugs, it makes no sense to shop for 2011 Ford F150 Ecoboost spark plugs, or worse yet, for a different vehicle altogether. Instead, shop based on the make, model, and year of your vehicle, as well as the particular engine you have under the hood.

Heat Range & Insulation

There’s a time and a place for hot and cold spark plugs. By evaluating the heat range, you know what each model is rated for and what type of insulation to expect. Heat dispersal is less with the low heat range plugs, allowing the temperature to rise quickly. However, high heat range plugs have a center electrode that doesn’t rise quickly in temperature.

Gap Size

The majority of spark plugs come pre-gapped for your convenience. However, you should always use a spark plug gap tool to check the measurements. For most Ecoboost engines, the best gap seems to be 0.030”, but you should refer to your owner’s manual to be sure.

Spark Plug Coating

Copper spark plugs are the cheapest variety on the market. You can use these with your F150 engine, but you will have to change them more often. If you are looking for better protection, more performance, and longevity, consider platinum or iridium instead. These last longer but also come with a higher price tag.

Thread Size

Spark plug thread size is always expressed with two numbers. The first shows the thread diameter, while the second number indicates the thread pitch. If you use spark plugs that don't feature the right thread size, you could cause damage to your cylinders and might not be able to get the plugs installed. 

Warranty & Life Expectancy

F150 Ecoboost spark plugs are no good if they don’t last long. No one wants to perform a Ford F-150 tune-up more often than needed. Evaluate how long the spark plugs should last and take a look at the company’s warranty too. If the company is sure of the product being produced, it will offer a lengthy warranty.

Price

To ensure the best value, you want a long F150 Ecoboost spark plug change interval. The best spark plugs for 2.7 Ecoboost F150 might cost more upfront, but if you get more mileage out of them, they could be more economical in the long run. Evaluate your options by figuring out the per-mile cost.

If you want the best spark plugs for a 2014 F150 Ecoboost, who can you trust? The obvious choice is to look at Ford to determine what the automaker thinks is best. In this case, all parts for the company are made by Motorcraft, which would make its spark plugs the most logical option. In fact, these copper core spark plugs are the only replacement on the market that is not only designed by Ford Motor Company but also manufactured by the automaker.

These spark plugs provide the same level of performance you got from your truck when it was brand new. Replacing your old, worn-out plugs with this option will add performance you forgot about. You might notice some horsepower gains as well as some savings at the fuel pump. Plus, Motorcraft provides customers a one-year warranty for further protection.

These options make the perfect 2011 F150 Ecoboost spark plug replacement, but they are not designed to be a high-performance upgrade. If you are demanding more from your tune-up, you might prefer to look at one of our platinum or iridium options instead. However, most average drivers are going to find that these OEM replacement spark plugs fit the bill just right.

Pros

  • OEM replacement
  • Designed by Ford
  • Durable construction
  • 1-year warranty

  • Not as high-performance

You don’t have to look far to find the best spark plugs for a 2015 F150 3.5 Ecoboost. Motorcraft makes a superior set of double platinum spark plugs that will increase your truck’s performance over copper options. The fine wire double platinum design creates the same spark plug that was installed in your truck from the factory, so you already know what to expect. Plus, it is designed to last for up to 100,000 miles.

While this is a double platinum spark plug, it does include an iridium-enhanced center electrode, which further increases the wear resistance and improves durability. If you push your truck to extremes or do a lot of heavy towing, you want to know that the spark plugs are designed to protect your engine from wear. These 2015 F150 Ecoboost spark plugs are some of the most highly rated on the market.

Plus, you don’t have to spend a fortune to perform a tune-up with a set of these plugs. Additionally, Motorcraft extends a one-year warranty to customers to ensure satisfaction. The only problem has been some shipment issues, but that really doesn’t have anything to do with the company or the product. In fact, it’s not uncommon for spark plugs to show up damaged.

Pros

  • Increased performance
  • Designed specifically for Ford
  • Long service life
  • 1-year warranty

Cons

  • Shipment issues

Another option from Motorcraft as the best spark plugs for a 2016 F150 Ecoboost is this model. It can effectively replace your worn-out plugs and is engineered for your vehicle.

The high melting point ensures optional resistance from erosion while still maintaining superior performance. Because this is a platinum set of plugs, you may only get 60,000 miles of life from it before needing a replacement. However, if you don’t do a lot of towing or hauling, you could push the tune-up to 100,000 miles.

These plugs deliver the spark needed to effectively ignite the mixture of air and fuel in the truck's combustion chamber. If you are currently struggling with an engine that misfires, uses too much fuel, or provides poor performance, these should help resolve some of your problems.

As with all of the Motorcraft plugs, this model comes with outstanding customer reviews. Plus, you get a one-year warranty to ensure there are no defects. The only downside is the price.

To do a complete tune-up with these plugs, you might spend a little more than expected. However, you are getting a high-quality plug that is built to last. Your truck engine is worth the extra expense, especially if it prevents motor failure down the road.

Pros

  • Stock replacement
  • Designed specifically for Ford
  • Durable construction
  • 1-year warranty

Cons

  • Expensive

With this set of six, you can perform a complete tune-up to your Ford F150 and know that your engine is protected. Depending on how long you plan to keep your truck, this set might even outlast your ownership. That’s because iridium plugs are designed to go 100,000 miles without replacement. Just think of all the other things you can be doing with your time instead of changing spark plugs. However, if you are hard on your truck, you might find that more frequent tune-ups are necessary.

The best part about this set is the exceptional amount of highly rated customer reviews. Plus, there is a one-year warranty for further peace of mind. As with some other models, this set has experienced some damage with shipping, so it’s something to be aware of.

You don’t have to purchase your spark plugs from the Ford Motor Company. If you prefer an aftermarket option, E3 offers what you need. This copper spark plug is designed to inhibit carbon deposits for a longer plug life. This company is so sure these plugs will last longer that they offer a five-year/100,000-mile warranty. So what makes these copper plugs go so far?

It might be the DiamondFire electrode technology that is used to create a strong spark. With this design, you can count on a flame that extends further into the cylinder, which produces additional localized pressure. You could see a power increase and better fuel economy as a result. Additionally, this plug is manufactured to reduce emissions for a better environment.

The question is, how much are you willing to pay for this type of performance? Some people see the price of this plug and balk. After all, it isn’t comparable to the price of other copper plugs on the market, but it’s also not created the same.

In fact, this plug deserves to be in a class with the iridium options because of the extreme performance and benefits offered. You can effectively protect your engine with the help of E3.

Pros

  • Designed for performance
  • Improves fuel efficiency
  • Reputable company
  • 5-year warranty

Cons

  • Expensive

You don’t have to look far to get the best of the best. NGK is a leader in spark plug technology, and this set is perfect for your F150. That's why we label these the best spark plugs for a 2011 F150 Ecoboost.

The Iridium IX spark plugs come with an ultra-fine center electrode that is just thick enough to provide exceptional durability and a long life. However, it’s still thin enough to create a consistent and accurate spark that your truck relies on.

These 2012 F150 Ecoboost spark plugs are made from metal that is six times harder than platinum, which is why they can last so much longer. Because of the durability, engineers were able to reduce the voltage requirements needed for this spark. In most situations, you can expect these plugs to last up to 100,000 miles. However, if you plan to do a lot of towing or heavy hauling, it’s best to change them sooner.

With that in mind, it’s unusual that NGK only provides customers with a 60-day warranty. This is far less than any other warranty we’ve looked at for F150 spark plugs. Even Motorcraft provides a one-year warranty, with E3 offering the longest at five years. Still, NGK enthusiasts swear by the protection and are happy to give up the extra warranty time.

Pros

  • Iridium performance
  • Reliable spark
  • Highly rated
  • Long service life

Cons

  • Only 60-day warranty

People Also Ask (FAQs)

Do spark plugs really increase horsepower?

While spark plugs alone aren’t going to add significant gains, replacing old, fouled out plugs will make a difference. You might notice a slight increase in horsepower, as well as better fuel efficiency and a reduction of emissions.

What year Ford F150 has spark plug problems?

Thankfully, there have been only a few issues with spark plugs and the Ecoboost engines. However, Ford has some other complaints about spark plug problems. 2004-2008 Ford F-150 trucks don’t require a spark plug replacement until 100,000 miles when the truck is out of warranty. It turns out carbon deposits would cake around the electrode, causing the plugs to get stuck and break in half.

How much are spark plugs for a Ford F150?

It depends on the level of quality you choose. You can find copper spark plugs for $5 or less a piece, but you will have to change them more often. It doesn't cost much more to get platinum or iridium spark plugs, but they tend to last longer. Sometimes, buying high-quality plugs actually reduces your tune-up cost because you perform service less often.

How often should you change spark plugs in a Ford F150?

For everyday driving, the Ecoboost maintenance schedule states that the spark plugs in an Ecoboost engine should be replaced every 100,000 miles. If you do a lot of towing or push your truck to the extreme, you might consider changing them at 60,000 miles instead.

What do the numbers on the spark plug mean?

Spark plug numbering systems show consumers the heat range, shell materials, gap, and measurements. Each manufacturer has its own way of numbering spark plugs. 

Where is the best place to buy replacement spark plugs for an F150 Ecoboost?
