Choosing the Right Aftermarket Spark Plugs
When shopping for new spark plugs, you'll see different types and brands. For the 2014-2018 Escape, especially the EcoBoost turbo engines, it's important to choose a quality part. The original plugs are typically long-life iridium or platinum types.
Pro Tip: Always stick with iridium or platinum plugs for the best performance and longevity. They are designed for modern engines like the one in your Escape and last much longer than basic copper plugs. Owners and mechanics strongly recommend using OEM-quality plugs for the turbocharged EcoBoost engines.
Aftermarket Brand Tiers
Not all brands are created equal. Based on owner feedback and mechanic consensus, here’s how the available brands generally rank for your Ford Escape:
- Top Tier (OEM Quality): Motorcraft is the original Ford part and a guaranteed fit. NGK and Denso are highly respected Japanese brands that are often original equipment for many automakers and are considered excellent, reliable alternatives.
- Mid Tier (Reliable Options): Autolite is a well-known brand that works well with Ford vehicles. Bosch offers quality plugs, though some users have reported issues with certain platinum types in other applications. Champion is a long-standing brand that offers dependable performance.
- Other Brands: Accel is generally geared more towards high-performance or racing applications. ACDelco is the OEM brand for General Motors (GM) and is not a typical choice for a Ford vehicle.
How Much Does a Spark Plug Replacement Cost?
The cost can vary depending on the parts you choose and whether you do the job yourself. The replacement is a straightforward task for a DIYer with basic tools.

Note: Some shops, especially dealerships, may quote significantly higher prices. One owner reported a dealer quote of $650, so it pays to call around or consider doing it yourself.
Frequently Asked Questions (FAQ)
When should I replace the spark plugs on my Ford Escape?
The recommended service interval is typically between 60,000 and 100,000 miles. However, if you notice any failure symptoms like misfiring or rough idling, you should inspect them sooner.
Is it hard to replace the spark plugs myself? 🎬 See this step-by-step walkthrough for replacing plugs at home.
No, this is a great DIY job for beginners. It requires basic tools like a ratchet, extensions, and a spark plug socket. The job usually takes about an hour. You'll need to remove the engine cover and ignition coils to access the plugs.
Do I need to gap the new spark plugs?
Most high-quality iridium and platinum plugs come pre-gapped. However, it is always a best practice to verify the gap with a feeler gauge before installation to ensure it matches your engine's specification. An incorrect gap can cause misfires.
Should I replace the ignition coils at the same time? 🎬 Watch: How to replace both spark plugs and ignition coils.
It's not required, but it is a good preventative measure. The ignition coils sit directly on top of the spark plugs and must be removed to replace them anyway. If your Escape has high mileage or you are experiencing a distinct misfire, replacing the coils along with the plugs can save you from doing the job twice.
Are there any recalls for 2014-2018 Escape spark plugs?
No, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from Ford for spark plug issues on the 2014-2018 Ford Escape.
