The Ford F-150 2.7 EcoBoost delivers impressive power and strong fuel efficiency, but its performance depends heavily on a healthy ignition system. Spark plugs play a vital role in combustion, throttle response, fuel economy, and overall engine reliability. A worn or low-quality plug can lead to misfires, rough idling, reduced acceleration, and poor gas mileage.
Drivers who tow heavy loads, commute daily, or push their trucks through demanding conditions often notice the difference that a quality set of spark plugs can make. Modern EcoBoost engines operate under high pressure and temperature, which makes spark plug selection more important than ever. The right option can support smoother operation, cleaner combustion, and long-term engine health.
This guide highlights the 5 best spark plugs for the F150 2.7 EcoBoost. Each recommendation focuses on durability, performance, compatibility, and value to help you find the ideal match for your truck.

Complete Buying Guide for Spark Plugs For F150 2.7 Ecoboost
Essential Factors We Consider
When selecting the best spark plugs for F150 2.7 Ecoboost, durability and ignitability are paramount. Because the Ecoboost uses twin turbos, the combustion chamber pressure is much higher than in naturally aspirated engines. We look for iridium or ruthenium tips, as these materials handle heat better and resist eroding over time.
Budget Planning
While you can find budget-friendly kits, remember that changing plugs on a truck can be a time-consuming task. Spending a little extra on high-quality iridium or ruthenium plugs often pays off because you won’t have to swap them out as frequently, saving you time and money in the long run.
Final Thoughts
Taking care of your ignition system is one of the easiest ways to keep your Ford running like new. Whether you choose the performance-oriented NGK Ruthenium plugs or a reliable OEM-style replacement, ensuring they are properly gapped and installed will keep your truck performing at its best.
Frequently Asked Questions
Q: How often should I change the spark plugs on my 2.7L Ecoboost?
A: Most experts recommend replacing the spark plugs every 60,000 to 100,000 miles, depending on your driving habits and if your truck is tuned.
Q: Do I need to gap my spark plugs before installation?
A: Yes, it is always best practice to check the gap on your new spark plugs against your vehicle’s service manual specifications before installing them to ensure perfect ignition.
Q: Will better spark plugs give me more horsepower?
A: While a high-quality plug can improve throttle response and stabilize idle, you generally won’t see a significant increase in horsepower without an ECU tune to optimize the new ignition timing.
