Our Top 7 Best Spark Plugs For 2014 F150 Ecoboost Reviews – Expert Tested & Recommended
1. Champion Platinum Spark Plugs for Ford F150 3.7L V6 and 3.5L EcoBoost Models 2011 to 2014
🌟 Key Features That Stand Out
- ✓ Precious Metal Construction: Built with durable platinum to resist erosion and maintain a steady spark.
- ✓ Perfect Fitment: Specifically designed for 2011-2014 Ford F-150 models with the 3.7L V6 or 3.5L EcoBoost.
- ✓ OE-Quality Replacement: Manufactured to match original equipment standards for a seamless installation.
- ✓ Anti-Seize Coating: Features a specialized shell plating to prevent corrosion and make future removal easier.
💡 Why We Recommend It
The Champion Platinum spark plugs are a fantastic choice for F-150 owners who want a balance of performance and long-term reliability. Because the 2014 EcoBoost engine runs at high pressures, you need a plug that won’t give up under heat. These plugs offer a very consistent spark that helps eliminate the “stutter” many Ford drivers experience during acceleration.
What makes these stand out is the heritage of the brand. Champion has a long history with Ford engines, and these platinum versions are designed to minimize wear and tear on your ignition system. They are incredibly easy to install and usually come with the correct gap right out of the box, though we always recommend a quick double-check.
🎯 Best For
This product is ideal for: daily drivers who want a reliable, “set-it-and-forget-it” spark plug that mimics factory performance.
⚖️ Pros and Cons
✅ Pros
- Excellent resistance to heat and fouling
- Very affordable price point for a 6-pack
- Direct fit for 2011-2014 model years
❌ Cons
💬 What Customers Say
“I noticed an immediate improvement in my F-150’s idle. The truck feels much more responsive when I step on the gas.”
— Verified Buyer
“Installed these in about an hour. They fit perfectly and fixed the misfire I was having in cylinder four.”
— Verified Buyer
2. NGK Iridium IX Spark Plugs for Ford F150 3.5L EcoBoost V6 Engines 2011 to 2019
🌟 Key Features That Stand Out
- ✓ Fine Wire Iridium Tip: Extremely high melting point and better electrical conductivity for high-performance engines.
- ✓ Trivalent Metal Plating: Provides superior anti-corrosion and anti-seizing properties without the need for anti-seize paste.
- ✓ Quick Start Technology: Designed to improve ignition in cold weather or during rapid acceleration.
- ✓ Tapered Ground Electrode: Reduces quenching to ensure a more complete and powerful combustion.
💡 Why We Recommend It
If you are looking for the absolute best in spark plug technology, NGK Iridium IX is hard to beat. Iridium is much harder and more conductive than platinum. For a twin-turbo engine like the 2014 EcoBoost, this means the spark is more consistent and the plug can withstand much more abuse before wearing out.
We recommend these particularly for owners who have a slightly older truck that might have lost some of its “pep.” The fine wire tip allows for a more focused spark, which helps burn every drop of fuel. This usually translates into a smoother engine feel and potentially a small bump in MPG.
🎯 Best For
This product is ideal for: performance enthusiasts and those living in colder climates who need consistent, fast starts.
⚖️ Pros and Cons
✅ Pros
- Superior conductivity compared to stock plugs
- Long service life (often 100k+ miles)
- Reduces engine misfires under load
❌ Cons
💬 What Customers Say
“I’ve always used NGK in my F-150. These Iridium IX plugs cured my rough idle instantly. Highly recommend!”
— Verified Buyer
“A bit pricey, but worth it for the piece of mind. The truck runs like new again.”
— Verified Buyer
3. A-Premium Iridium Platinum Spark Plugs for Ford F150 3.5L EcoBoost V6 Engines 2011 to 2019
🌟 Key Features That Stand Out
- ✓ Dual-Material Design: Iridium center electrode and platinum ground core for the best of both worlds.
- ✓ Precise 0.032″ Gap: Optimized specifically for the tight tolerances required by Ford’s turbo systems.
- ✓ Extended Lifecycle: Engineered to last between 80,000 and 100,000 miles, reducing maintenance frequency.
- ✓ Wide Compatibility: Fits almost every 3.5L EcoBoost engine from 2011 through 2019.
💡 Why We Recommend It
A-Premium has built a reputation for providing high-quality replacement parts at a fraction of the cost of dealership parts. These spark plugs are the ultimate value play. They use a hybrid design that puts Iridium where the spark is most intense and Platinum on the core for stability. This combo offers great longevity without breaking the bank.
For a 2014 F-150 owner who wants to keep their truck in top shape but is on a budget, these are a no-brainer. The 0.032″ gap is exactly what Ford recommends for the Gen 1 EcoBoost to prevent “spark blow out” under boost, meaning you can trust these during heavy towing or highway merging.
🎯 Best For
This product is ideal for: budget-conscious owners who still want the high-performance benefits of Iridium and Platinum materials.
⚖️ Pros and Cons
✅ Pros
- Most affordable Iridium/Platinum hybrid
- Correct gap for EcoBoost engines
- Excellent long-term durability
❌ Cons
💬 What Customers Say
“I was skeptical because of the price, but these have been in my truck for 10k miles now and it runs perfectly.”
— Verified Buyer
“The packaging was great and the plugs were gapped correctly. Saved me about $40 over the local auto parts store.”
— Verified Buyer
4. OverstockDirect OEM Iridium Spark Plugs SP580X for Ford F150 3.5L EcoBoost V6
🌟 Key Features That Stand Out
- ✓ Genuine OEM Part: These are the exact SP580X (Motorcraft) plugs used by Ford dealerships.
- ✓ Maximum Durability: Designed specifically to withstand the high cylinder pressures of turbocharged engines.
- ✓ Validated Performance: Meets all Ford Motor Company factory specifications for emissions and power.
- ✓ Pre-Gapped Precision: Usually arrives with the factory-recommended gap for immediate install.
💡 Why We Recommend It
When it comes to the EcoBoost engine, many mechanics will tell you to “stick with stock.” Ford spent millions of dollars testing the SP580X plugs to ensure they work perfectly with the F-150’s computer system. If you want the peace of mind that your truck is running exactly as the engineers intended, these are the plugs for you.
Because these are OEM Iridium plugs, they are much better at handling the “heat soak” that occurs when you are towing or driving in heavy traffic. They help prevent pre-ignition and knocking, which are common issues in 2014 models if the plugs are worn out. It’s a premium product for a premium engine.
🎯 Best For
This product is ideal for: owners who prefer to stick with factory-original parts and want guaranteed compatibility.
⚖️ Pros and Cons
✅ Pros
- Official Ford OEM replacement part
- Highest level of quality control
- Superior heat dissipation
❌ Cons
💬 What Customers Say
“Don’t waste time with cheap plugs. These SP580X plugs are what the truck was designed for. Zero issues.”
— Verified Buyer
“Installed these on my 2014 EcoBoost at 90k miles. The old plugs were toasted. Huge difference in smoothness.”
— Verified Buyer
5. Ignition Coil Pack and Iridium Spark Plugs for Ford F150 3.5L EcoBoost V6 2011 to 2017
🌟 Key Features That Stand Out
- ✓ Complete 12-Piece Set: Includes 6 high-energy ignition coils and 6 performance iridium spark plugs.
- ✓ 3-Pin Connector Fitment: Specifically designed for the Turbo/EcoBoost models (does not fit naturally aspirated engines).
- ✓ Improved Fuel Efficiency: Engineered to deliver a consistent spark that reduces unburnt fuel and emissions.
- ✓ Plug-and-Play Design: Coils and plugs are ready for installation without needing complex tools.
💡 Why We Recommend It
If your 2014 F-150 has over 100,000 miles, it might be time to replace more than just the plugs. Ignition coils can weaken over time, leading to weak sparks and engine hesitations. This bundle from ENA provides a complete ignition overhaul. By replacing the coils and plugs at the same time, you eliminate the guesswork of tracking down a misfire.
The quality of these coils is quite impressive for the price point. They are built with high-grade silicone and copper to ensure they don’t crack under the immense heat of the EcoBoost’s engine bay. It is a cost-effective way to restore that factory-fresh power to your truck.
🎯 Best For
This product is ideal for: owners doing a high-mileage tune-up who want to refresh their entire ignition system at once.
⚖️ Pros and Cons
✅ Pros
- Massive savings compared to buying parts separately
- Solves complex misfire issues effectively
- Iridium plugs included for longevity
❌ Cons
💬 What Customers Say
“My truck was stumbling hard. This kit fixed it in under two hours. Much cheaper than the dealer quote!”
— Verified Buyer
“Plugs were gapped correctly and the coils snapped right into place. No more check engine light.”
— Verified Buyer
6. Ignition Coil and SP534 Double Iridium Spark Plugs for Ford F150 3.5L EcoBoost 2011 to 2017
🌟 Key Features That Stand Out
- ✓ Double Iridium Technology: Iridium on both the center and ground electrodes for maximum spark stability.
- ✓ 100,000 Kilometer Life: Rated for extreme longevity even in high-heat environments.
- ✓ Ferrite Noise Suppressor: Prevents radio frequency interference (RFI) for clear electronics operation.
- ✓ Advanced Thermoplastic: Coil connectors resist fractures caused by thermal cycling.
💡 Why We Recommend It
What makes this set unique is the “Double Iridium” plug design. In a standard plug, only the tip is Iridium. In these, both sides of the spark gap use this ultra-hard metal. This is a game-changer for the 2014 EcoBoost because it prevents the gap from widening over time, which is the number one cause of misfires in these trucks.
The coils included in this kit also feature a stainless-steel spring that provides better contact with the plug. This ensures that every bit of voltage from the coil reaches the spark plug without leaking. It’s a heavy-duty solution for a truck that works hard.
🎯 Best For
This product is ideal for: heavy-duty users and those who tow regularly and need the most stable spark possible.
⚖️ Pros and Cons
✅ Pros
- Double Iridium is the top tier of durability
- Reduces electrical noise/interference
- One-year product service guarantee
❌ Cons
💬 What Customers Say
“The build quality of the coils feels very solid. My F-150 hasn’t run this smooth in years.”
— Verified Buyer
“Great value for the money. Everything fit perfectly on my 2013 and 2014 trucks.”
— Verified Buyer
7. Replacement Ignition Coil Pack and Spark Plugs for Ford F150 3.5L V6 EcoBoost 2011 to 2017
🌟 Key Features That Stand Out
- ✓ Premium Material Standards: Manufactured to meet or exceed OEM specifications for reliability.
- ✓ Comprehensive Fitment: Covers Ford F-150, Expedition, Explorer, and even Police Interceptor models.
- ✓ Misfire Solution: Designed to correct issues like rough idling, stalling, and power loss.
- ✓ Complete Combo: Provides all 6 coils and 6 plugs in one convenient package.
💡 Why We Recommend It
The NPAUTO set is a fantastic alternative for professionals or DIYers who need a reliable ignition kit without the markup of a brand-name dealership. We like that this set is rigorously tested for the 3.5L V6 Turbocharged engine. These engines are known to be “picky” with their electrical components, and this kit handles the load well.
If you’ve noticed your fuel economy dipping or your truck struggling to start on cold mornings, this is a solid investment. Replacing both the coils and the plugs ensures that you aren’t putting a “new plug in a tired coil,” which often leads to the new plug failing prematurely anyway.
🎯 Best For
This product is ideal for: Ford owners who need a full ignition refresh and want a high-quality aftermarket alternative to OEM prices.
⚖️ Pros and Cons
✅ Pros
- Very consistent voltage output across all coils
- Direct replacement for multiple part numbers
- Durable construction for long-haul driving
❌ Cons
💬 What Customers Say
“I’ve been using these for six months and they haven’t missed a beat. Saved a lot of money over the dealer.”
— Verified Buyer
“The truck feels more powerful and the gas mileage improved by almost 2 MPG. Definitely worth the buy.”
— Verified Buyer
Complete Buying Guide for Best Spark Plugs For 2014 F150 Ecoboost
Essential Factors We Consider
When shopping for spark plugs for a turbocharged engine like the 2014 EcoBoost, the most important factor is the material and the gap. Turbo engines run much hotter and have higher cylinder pressure, which can actually “blow out” a weak spark. We recommend Iridium or Platinum plugs because they can handle this heat without melting or eroding too quickly. Furthermore, gapping is critical; for the 2014 model, a gap of 0.030″ to 0.032″ is generally the sweet spot to ensure the spark stays strong under boost.
Budget Planning
You don’t need to spend a fortune, but you shouldn’t go for the cheapest copper plugs either. A 6-pack of quality Platinum plugs usually costs between $30 and $40. If you want the longevity of Iridium, expect to pay $50 to $70. If your truck is reaching 100,000 miles, it is often more cost-effective to buy a bundle that includes ignition coils. These bundles range from $100 to $140 and can save you from doing the job twice if a coil fails shortly after you change the plugs.
Final Thoughts
Maintaining your ignition system is the easiest way to keep your F-150 feeling like a new truck. Whether you choose the factory-standard Motorcraft (OEM) plugs or a high-performance NGK set, the key is consistency. Make sure you check your gaps, use a bit of dielectric grease on the coil boots, and torque them to the proper specs. Your EcoBoost engine will thank you with better power and smoother rides.
Frequently Asked Questions
Q: How often should I change spark plugs in a 2014 F-150 EcoBoost?
A: While Ford suggests longer intervals, most EcoBoost owners and mechanics recommend changing them every 30,000 to 45,000 miles. Turbocharged engines are much harder on plugs than naturally aspirated ones.
Q: What happens if I use the wrong spark plug gap?
A: If the gap is too large, the spark might not be able to jump the distance under high boost, causing a misfire. If it’s too small, the spark may be too weak to fully ignite the fuel, leading to poor efficiency.
Q: Do I need to replace my ignition coils every time I change plugs?
A: No, but you should inspect them for cracks or burns. Most owners replace coils every 100,000 miles as preventative maintenance.
