Top 5 Best Spark Plugs for Ford Edge (2026) — Tested & Reviewed
The Ford Edge is a popular mid-size crossover that has been in production since 2007 across three generations. Whether you own a 2007-2014 (1st gen), 2015-2018 (2nd gen with the 2.0L EcoBoost or 2.7L EcoBoost), or a 2019-2025 (3rd gen refresh) model, maintaining your spark plugs is one of the most important things you can do for engine performance, fuel economy, and longevity.
Good spark plugs ensure proper ignition of the air-fuel mixture, which directly affects acceleration, idle quality, and emissions. Worn or incorrect spark plugs cause misfires, reduced MPG, rough idling, and even engine damage over time.
My Top Pick: For most Ford Edge owners, the NGK 94143 ILZKR6B-6G Laser Iridium spark plug offers the best combination of performance, longevity, and value. With iridium construction for a precise spark and platinum center electrode for durability, these plugs are factory-direct replacements that deliver exceptional spark consistency and up to 100,000-mile service intervals.

How to Choose the Right Spark Plugs for Your Ford Edge
1. Know Your Engine
The Ford Edge was offered with several engines over its production years:
- 2007-2010: 3.5L V6 (Duratec) — uses standard copper or platinum plugs
- 2011-2014: 3.5L V6 (Duratec) and 2.0L EcoBoost — iridium recommended for EcoBoost
- 2015-2018: 2.0L EcoBoost and 2.7L EcoBoost — iridium or platinum required
- 2019-2025: 2.0L EcoBoost and 2.7L EcoBoost — iridium is the best choice for these turbocharged engines
2. Iridium vs Platinum vs Copper
- Copper: Cheapest but shortest life (30K-50K miles). Good for budget builds.
- Platinum: Mid-range durability (60K miles). Good compromise between cost and longevity.
- Iridium: Most expensive upfront but longest life (100K miles). Best for EcoBoost turbo engines that run hotter and demand better ignition.
3. Replacement Interval
Ford recommends spark plug replacement every 30,000-100,000 miles depending on the plug type and engine. EcoBoost engines typically require more frequent changes due to higher combustion chamber temperatures. Many Ford Edge owners find the best results replacing plugs every 60,000 miles even if the manufacturer says 100K.
Final Verdict — Our Recommendations
Best Overall: NGK 94143 ILZKR6B-6G Laser Iridium — The perfect balance of performance, durability, and price. Fits the widest range of Ford Edge engines and delivers the reliability you need year after year.
Best Premium: Denso 3476 Ir Power — If you want the absolute best spark quality available and don’t mind paying a premium, Denso’s ultra-fine iridium tip gives you the hottest, most focused spark on the market.
Best Budget: Bosch CopperPlus — When you’re on a tight budget or running a daily-driver Edge that sees heavy use, Bosch’s CopperPlus gives you reliable performance at a fraction of the cost of iridium plugs.
Quick Tip: Always replace spark plugs in sets of 4 (or 6 for V6 engines). Mixing old and new plugs can cause uneven firing and reduce performance. Also, always check the gap before installation even if the plugs are “pre-gapped.”
