Complete Buying Guide for Best Spark Plugs For F150 Ecoboost
Essential Factors We Consider
Choosing the best spark plugs for your F150 EcoBoost isn’t just about picking a brand. You need to think about material, heat range, and compatibility. Iridium and ruthenium plugs last longer and spark better than copper, which is key for turbocharged engines. Always check your truck’s year, engine size (2.7L or 3.5L), and whether it’s stock or modified. Getting the right fit prevents headaches and keeps your engine happy.
Budget Planning
Spark plugs range from affordable to premium. You can spend around $50 for a basic iridium set or over $100 for ruthenium or combo packs. My advice: don’t skimp. Cheap plugs might save money now but cost you in fuel economy and performance later. For most drivers, mid-range iridium plugs offer the best balance. If you’re keeping your truck for years, investing in ruthenium or a coil-plug set can pay off by reducing future maintenance.
Final Thoughts
At the end of the day, the best plug is one that matches your driving style and truck’s needs. For daily commuting, a reliable iridium plug like our Best Choice NGK set is perfect. For towing or performance, consider colder plugs or ruthenium options. And if you’re dealing with misfires, a combo pack with coils might be the smartest move. Take your time, read reviews, and you’ll find the right spark to keep your EcoBoost running strong.
Frequently Asked Questions
Q: How often should I change spark plugs in my F150 EcoBoost?
A: Ford recommends every 60,000 to 100,000 miles for EcoBoost engines, but it depends on your driving. If you tow often or notice rough idle, poor fuel economy, or misfires, check them sooner. Iridium and ruthenium plugs can last longer, up to 100,000 miles or more.
Q: Can I use copper spark plugs in my EcoBoost?
A: It’s not recommended. EcoBoost engines run hotter and under higher pressure, so they need durable materials like iridium or ruthenium. Copper plugs wear out faster and can cause performance issues. Stick with premium plugs for best results.
Q: Do I need to gap spark plugs for my F150?
A: Yes, usually. Even if plugs come pre-gapped, it’s smart to check with a gap tool. The correct gap for most EcoBoost engines is around 0.028 to 0.030 inches. Improper gapping can lead to misfires and poor performance.
Q: What’s the difference between iridium and ruthenium spark plugs?
A: Both are premium materials, but ruthenium is newer and even more durable. It handles heat and wear better, potentially lasting longer. Iridium is still excellent and more common. Ruthenium is a great upgrade if you want the latest tech and don’t mind paying a bit more.
Q: Should I replace ignition coils when changing spark plugs?
A: Not always, but it can be a good idea, especially if your truck has high mileage or you’re experiencing misfires. Coils wear out over time, and replacing both together ensures optimal performance. Combo packs like those in our list make this easy and cost-effective.
Finding the best spark plugs for your F150 EcoBoost doesn’t have to be a chore. From our top pick NGK Iridium IX to budget-friendly OEM options and high-tech ruthenium sets, there’s a perfect match for every need and budget.
