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.6 Best Spark Plugs for F150 Ecoboost Reviewed

6. NGK LTR6IX-11 # 6509
Best Spark Plugs for 2011 Ecoboost
Compatible Vehicles | 2011-2017 Ford F-150 3.5L |
Plug Material Coating | Iridium |

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.
