One of those routine maintenance things is changing the engine’s spark plug to ensure a better performance. It’s been a while since ford has introduced its EcoBoost engine.

1. Motorcraft sp-534/sp-580 spark plug – 2.7 L engine 2011-2020

If you randomly search on the internet with the keyword best spark plugs for ford f150, this is the most common result you will find. It doesn’t really matter whether you add the word EcoBoost with the keyword or not. This is undeniably the best spark plug you can find online for your Ford F150 EcoBoost 2.7L engine variant.

While researching this content, it was really hard for me to find the actual spark plugs because there’s an issue regarding them that most don’t last long enough. F-150 owners know that they will be pushing their cars to their limits. So, the spark plug has to have a certain endurance level for maximum distance coverage.

The factory-grade spark plugs that come with the car usually need a change after 60k miles. While changing the spark plug, most people faced this problem that other spark plugs cause misfire while cruising at 60 mph. When they switched to this, it was okay for 70k miles and didn’t cause any misfire whatsoever.

People have this fascination for OEM spark plugs, but to be honest, when compared with this one, most people have agreed that the value for money of the Motorcraft spark plugs is way better than that offered by OEM.


? Pros:
  • Reported to give certain Horsepower increase right after installation
  • Recommended change is after 60,000 miles, which is at least 10,000 miles more than competitors
  • Maximum recorded use was up to 90,000 miles on an EcoBoost engine.
  • Increases fuel efficiency by 2 miles per gallon
  • Can be used in a 3.5L EcoBoost engine as well


? Cons:


  • No specific gap level mentioned, have to select that according to your own discretion
  • Some have reported problems with delivery issues, didn’t get the exact amount what they ordered

2. Motorcraft sp-550 spark plug – 3.5 L engine 2011-2020

EcoBoost engines are designed to ensure better performance with lower fuel consumption. With an EcoBoost engine, you will get more horsepower and better fuel efficiency than normal engines.

But when we expect an engine to deliver something like this, it’s obvious that it will take a toll on every part of the engine that is directly connected with power and efficiency.

The spark plug is that part of the engine that takes the most toll. So, you cannot just pick up any spark plug while changing the existing ones.

As I’ve mentioned earlier, the stock spark plugs give up to 70,000 miles; to get something similar to that, you need the best spark plugs available for your ford F150 EcoBoost 3.5L engine variant.

The Motorcraft sp-550 spark plugs, mainly manufactured by NGK with their similar high-grade quality but lower. That means monstrous value for money.

Yes, it won’t be as good as NGK’s flagship product. But undeniably better than almost any other product that you can put your hands on.

This product comes with a full manufacturer warranty for a certain period for quality assurance. Unlike most other spark plugs, this is not a dedicated one.

This means this spark plug can fit several other models and different engines as well with a proper gap measurement.

What’s best about this specification is that it delivers the same performance level on every vehicle, even better on non-EcoBoost engines.


? Pros:
  • Manufacturer warranty, duration unknown
  • Fits several types of engine models
  • Increases engine power and performance
  • Stick shift response is accurate
  • Pre Gapped accurately for EcoBoost engine
? Cons:
  • Mileage coverage is unknown, reported to be functional for up to 60,000 miles
  • Some say recommended mileage is 15,000 only but for extreme usage.


3.NGK iridium ix plug number 6509 spark plug – 3.5 L engine 2011-2020

The build material for spark plugs is important because a car engine depends on the spark plugs to deliver maximized performance.

So, if the spark plugs don’t have a certain amount of build endurance, they will get shot long before you expect them to last.

NGK came up with a solution to that. It’s not that nobody thought about the build material of spark plugs, but NGK decided to go for the highest build endurance level with Iridium spark plugs.

So far, people have loved the fact that instead of platinum infusion with metal, car parts manufacturers are now focusing on making iridium spark plugs.

It’s because platinum is an expensive metal that automatically increases the price of spark plugs. Then again, you could go for non-platinum infused spark plugs. Thus you’ll have to sacrifice the endurance assurance.

But iridium spark plugs have insane value for money. Iridium is a non-expensive tough metal that is best for making spark plugs for cars that require high endurance levels.

So, if you consider buying any spark plugs for endurance, this is the one to go for getting better performance and efficiency.


? Pros:
  • Best quality build material
  • Increases engine performance
  • Best value for money
  • Increase fuel efficiency
  • Recommended change is more than 60,000 miles
? Cons:
  • No actual record of longevity
  • Some batches had an Issue with the ceramic insulator ring to get cracked

Buyers Guide


Things to look for before buying the Best Spark Plugs for f150 EcoBoost

Spark plugs are an integral part of your engine. You can’t literally drive your car without changing them when it’s time. The engine starts to misfire; the power lowers, fuel efficiency decreases.

And most importantly, the car might stop and not start at any point. So, when you’re buying spark plugs for your car, you have to be very cautious. That’s why we recommended the best ones you can find all over the internet.

EcoBoost is a very complicated engine. So, most reviewers are not even comfortable enough to recommend spark plugs for EcoBoost engines. How did we manage to do that? You’ll understand by taking a look at this buyers’ guide.

Build material

If you’re expecting a long service from any spark plugs, you have to consider the build material of them. Because the amount the pressure a spark plug gets from the engine is something worth having a better endurance for.

Most importantly, we are talking about EcoBoost engines here. EcoBoost engines are designed in such a way that they push the engine block over the limit to get things done.

Better fuel efficiency and power require better parts of the engine, which can endure extreme fatigue.

Spark plugs being a very important part of the power and fuel efficiency, definitely need to have a very good build quality.

Recommended Miles

Spark plugs are not a part that you can change every now and then. Core engine parts are made in a way that you don’t have to change them too frequently.

But when it comes to an EcoBoost engine designed for busting the engine out to its limits, parts wear off quicker than quicksand.

So, when buying spark plugs, do check for recommended miles. We recommend using spark plugs that have 60,000 miles on them. That’s great value for money if you can procure that mileage from spark plugs.

Performance Increase

Spark plugs do one thing. They are present in a car to keep the engine properly functional. When spark plugs function properly, they keep the performance of the car high and fuel consumption low.

The basic build of an EcoBoost engine is made to ensure better performance with lower fuel consumption.

EcoBoost engines are known for being highly fuel-efficient. Ford F150’s are fuel-hungry cars. Bigger engine blocks with more power mean more fuel consumption.

EcoBoost engines are designed in a way for people who want to save money and still enjoy the power deliverance of Ford.

If you are not conscious about what spark plugs you are putting in the engine, that might negate the only thing you bought an EcoBoost version for. That is to decrease or normalize the power level and fuel efficiency.
