Top 5 Best Spark Plugs for Ford F150 EcoBoost
When it comes to keeping your Ford F-150 EcoBoost running at peak performance, choosing the right spark plugs is essential. The EcoBoost engine relies on precise ignition timing and consistent spark delivery to deliver its signature blend of power and fuel efficiency. Over time, factory spark plugs wear down, leading to misfires, rough idling, and reduced gas mileage. That’s why upgrading—or replacing—with high-quality spark plugs can make a noticeable difference in throttle response, engine smoothness, and long-term reliability. Whether you’re driving a 2.7L, 3.3L, or 3.5L V6 EcoBoost, we’ve tested and reviewed the best options available in 2024 to help you make a confident, informed decision.

Complete Buying Guide for Best Spark Plugs For Ford F150 Ecoboost
Essential Factors We Consider
Choosing the right spark plug for your Ford F-150 EcoBoost isn’t just about fit—it’s about matching material, heat range, and design to your driving habits. We evaluate electrode material (copper, platinum, Iridium, Ruthenium), gap specifications, compatibility with your engine size (2.7L, 3.3L, or 3.5L), and real-world performance data. OEM specifications matter, but so does long-term value. Always check your owner’s manual for the recommended replacement interval—typically every 60,000 to 100,000 miles depending on the plug type.
Budget Planning
Spark plug prices vary widely: basic copper sets start around $20, while premium Iridium or Ruthenium kits can cost $80–$120. Consider total cost of ownership—cheaper plugs may need replacement sooner, costing more over time. If you’re also replacing coils, combo kits (like #3 above) offer the best value. For most owners, spending $50–$70 on a quality set of Iridium plugs strikes the perfect balance between performance and affordability.
Final Thoughts
Your F-150 EcoBoost deserves spark plugs that keep up with its turbocharged demands. Whether you choose OEM Motorcraft for peace of mind, NGK for top-tier performance, or a budget-friendly bundle for a full refresh, the right choice will reward you with smoother operation, better fuel economy, and fewer headaches down the road.
Frequently Asked Questions
Q: How often should I replace spark plugs in a Ford F-150 EcoBoost?
A: Most EcoBoost engines use long-life Iridium or Platinum plugs rated for 60,000 to 100,000 miles. Check your owner’s manual—Ford typically recommends inspection at 60k and replacement by 100k, but severe driving conditions (towing, stop-and-go traffic) may require earlier changes.
Q: Can I use non-OEM spark plugs in my EcoBoost engine?
A: Yes—but stick to reputable brands like NGK, Denso, or Motorcraft. Avoid cheap copper plugs, as they wear quickly under high boost and can cause misfires. Always match the heat range and gap specification to your engine.
Q: Will new spark plugs improve my F-150’s fuel economy?
A: Absolutely. Worn plugs reduce combustion efficiency, forcing the engine to work harder. Fresh plugs restore optimal spark, which can improve MPG by 2–5%, especially noticeable in city driving.
Q: Do I need to replace ignition coils when changing spark plugs?
A: Not always—but if your truck has misfire codes, rough idle, or high mileage, replacing coils alongside plugs ensures a complete ignition refresh. Coil-on-plug systems in EcoBoost engines benefit from simultaneous replacement.
Q: Are pre-gapped spark plugs necessary?
A: For most modern plugs, yes. EcoBoost engines are sensitive to gap variance. Pre-gapped plugs save time and prevent installation errors. Always double-check with a gap tool if unsure.
