Complete Buying Guide for Best Spark Plugs For 2016 F150 3.5 Ecoboost
Recommended Best Deal Products
Essential Factors We Consider
When shopping for spark plugs for a turbocharged engine like the 3.5L EcoBoost, the most important factor is material. Iridium is the gold standard because it has a high melting point and resists electrical erosion better than platinum or copper. Another critical factor is the spark gap. Ford recommends a gap between 0.030″ and 0.033″ for these engines. A gap that is too wide can lead to “spark blowout,” where the high-pressure air from the turbos actually extinguishes the spark before it can ignite the fuel.
Budget Planning
You can find basic iridium plugs for around $30-$50 for a set of six. However, if your truck has high mileage, we strongly suggest budgeting for a complete coil and plug kit, which usually runs between $90 and $150. Replacing the coils at the same time as the plugs ensures that you aren’t putting brand-new plugs on a weak, failing coil, which would only result in continued misfires and wasted labor time.
Final Thoughts
Maintenance is the key to longevity for the 2016 F-150. Because the EcoBoost is a direct-injection engine, it is naturally harder on ignition components. Changing your plugs every 30,000 to 50,000 miles (even if the manual says 100k) is a cheap way to keep your truck running efficiently and prevent more expensive repairs down the road.

Frequently Asked Questions
Recommended Best Deal Products
Q: How do I know if my spark plugs are bad in my F-150?
A: Common signs include a rough idle, a “shudder” or hesitation when accelerating (especially in high gear), a decrease in fuel economy, and the presence of a Check Engine Light with codes like P0301 through P0306.
Q: Do I need to gap new spark plugs?
A: Even if the box says “pre-gapped,” you should always check them with a feeler gauge. For the 3.5L EcoBoost, aim for a gap of 0.032 inches to ensure the best performance under boost.
Q: Should I replace my ignition coils too?
A: If your truck has over 100,000 miles or if you are already experiencing misfires, it is highly recommended to replace the coils. Coil failure is common in EcoBoost engines due to the high heat under the hood.
Q: Can I use platinum plugs instead of iridium?
A: You can, but iridium is preferred. The EcoBoost engine’s high cylinder pressure will wear down platinum electrodes much faster than iridium, leading to a shorter service life.
