Helpful Comparison Short Insights
Choosing the right plug starts with knowing your engine. For drivers with the larger 2.0L or 2.5L L4 engines (non-turbo), options like the A-Premium Iridium Platinum (0.052″ gap) offer fantastic longevity and require less frequent changing. If you have the popular 1.5L EcoBoost engine, you absolutely must choose plugs specifically designed for that platform and the smaller 0.028″ gap, such as the dedicated options from TAUTOY or A-Premium 1.5L.
When your vehicle is suffering from consistent misfires or sputtering, consider replacing the entire ignition system. The Ignition Coil Pack and Spark Plug sets (like the LCWRGS for 2.0L/2.5L or the specialized kit for the 1.5L EcoBoost) provide the most reliable, comprehensive fix by refreshing both the plugs and the coils simultaneously.
For brand preference, Champion provides two excellent, reliable choices: their Platinum line is the budget-friendly workhorse, while the Iridium line offers the most extended life and superior spark performance for the non-turbo engines.
Final Verdict: Which Plug Is Right For Your Ford Fusion?
The choice of the best spark plugs for your Ford Fusion really boils down to your specific engine size and driving priorities.
- If you own a 2.0L or 2.5L L4 (Non-Turbo) and prioritize longevity: Go with the A-Premium Iridium Platinum Spark Plugs (L4 2.0L 2.3L 2.5L). Their 80,000 to 100,000-mile lifespan is hard to beat for long-term economy.
- If you own a 1.5L EcoBoost (Turbo) and prioritize performance and smoothness: Choose the TAUTOY SP539 91924 Spark Plugs Platinum Iridium (1.5L). The design focuses on efficient combustion, giving you quick throttle response.

Complete FAQs About the Top Spark Plugs for Ford Fusion.
How often should I replace the spark plugs in my Ford Fusion?
The replacement interval heavily depends on the type of spark plug installed. Standard copper plugs need changing every 30,000 miles. However, the premium iridium and platinum spark plugs recommended for the Ford Fusion, especially those engineered to OE standards, can last between 80,000 and 100,000 miles. Always check your owner’s manual for the specific recommendation for your model year and engine type.
What is the difference between Iridium and Platinum spark plugs?
Platinum spark plugs offer better durability and longevity than traditional copper plugs and are a great mid-range option. Iridium spark plugs are the premium choice; Iridium is stronger and harder than Platinum, allowing for a much finer electrode tip. This results in a more concentrated, powerful spark and provides the longest service life—often exceeding 100,000 miles.
Does the engine size (1.5L vs. 2.5L) affect the spark plug I need?
Absolutely. The Ford Fusion uses different spark plug specifications depending on the engine. If you have the turbocharged 1.5L EcoBoost engine, you require plugs with a much smaller gap (typically around 0.028 inches) and higher heat tolerance to handle the turbo pressure. Standard 2.5L L4 engines use a wider gap (closer to 0.052 inches). Using the wrong plug size or gap can lead to severe engine misfires or damage, especially in EcoBoost models.
Should I replace my ignition coils along with my spark plugs?
While spark plugs have a much shorter lifespan than coils, it’s often a good practice to replace both simultaneously, particularly if your vehicle is high mileage (over 100,000 miles) or if you are experiencing repeated misfires. Failing ignition coils can lead to hesitation, poor gas mileage, and ultimately damage the new spark plugs. Purchasing a bundled set (like the LCWRGS or 1.5L coil pack kits) is the easiest way to ensure a full refresh of the Ford Fusion ignition system.
Are pre-gapped spark plugs reliable, or should I check the gap?
Most high-quality spark plugs marketed as OEM replacements for the Ford Fusion (especially Iridium and Platinum types) come accurately pre-gapped from the factory, which is ideal. However, plugs can shift during shipping. It is always wise to double-check the spark plug gap size with a proper gapping tool, especially for the sensitive Ford Fusion EcoBoost models where the precise gap is crucial for optimal performance.
Can old or faulty spark plugs impact my gas mileage?
Yes, they definitely can. Worn-out spark plugs deliver a weak or inconsistent spark, leading to incomplete combustion of fuel in the cylinder. This inefficiency forces the engine to burn more fuel to maintain power, directly resulting in noticeable drops in Ford Fusion fuel economy and a decrease in overall performance. Replacing them is a key step in regaining lost efficiency.
