How much does it cost to replace spark plugs in a Ford Explorer?
The typical price range for a spark plug replacement on a Ford Explorer is about $200 to $500, depending on the engine and where you service it. Expect higher costs at a dealership and lower prices at an independent shop or quick-lube center.
Ford Explorers have used a couple of different engines over the years, with four-plug configurations common in newer 2.3L EcoBoost models and six-plug setups found in some V6 variants. Because modern engines use coil-on-plug ignition, labor time—and therefore price—depends largely on how easy it is to reach the plugs and whether any ignition coils or boots need replacement. Plugs themselves vary in price by type (copper, platinum, iridium), which also drives the total. Regional labor rates and whether OEM (original equipment) or aftermarket plugs are installed will further influence the final bill.
What affects the price
Several factors determine the final cost beyond simply counting the number of plugs. Here’s what typically matters:
- Engine configuration (number of spark plugs: four for 2.3L EcoBoost, six for many V6 options).
- Spark plug type (copper vs platinum vs iridium) and whether OEM parts are used.
- Labor rate and location (dealer services tend to be higher than independent shops).
- Accessibility and required extra parts (coil-on-plug systems can require coil or boot replacement if worn).
In short, the price is driven by engine design, plug type, and how long the mechanic expects to work under the hood. Getting a few written estimates from different shops is the best way to gauge what you’ll pay in your area.
Typical cost ranges by engine configuration
Below are broad estimates that reflect common Explorer configurations as of 2025. These include parts and labor and assume standard coil-on-plug ignition. Actual quotes may vary by region and shop.
- Four-spark-plug configurations (most 2.3L EcoBoost models): Roughly $150 to $420 total, depending on plug type and local labor rates.
- Six-spark-plug configurations (3.0L V6 or other six-plug engines used in some Explorers): Roughly $250 to $650 total, with higher quotes possible at the dealership or in expensive markets.
Keep in mind that, in some cases, dealerships can price higher due to overhead, while independent shops may be able to offer competitive, lower-priced quotes. If your vehicle has especially tight access or if a faulty coil/boot is detected, costs can edge toward the upper end or beyond.
What to expect during the service
Here's a typical sequence when a shop performs spark plug replacement on an Explorer with coil-on-plug ignition:
- Verification of the engine type and the recommended plug type for your model year.
- Electrical system safety checks and engine coolant/air intake precautions as needed.
- Removal of ignition coil packs and spark plugs, followed by cleaning and proper torquing of new plugs.
- Inspection of coils/boots and replacement if wear is evident or suggested by the technician.
- Reassembly, in-engine tests, and a brief test drive to confirm smooth operation.
The exact steps can vary by model year and engine, but the general flow is consistent: access, replace, inspect, and verify the engine runs cleanly after service.
Ways to save money on spark plug replacement
If you’re looking to minimize costs, consider these practical steps:
- Ask for the recommended plug type for your engine and avoid unnecessary upgrades unless they’re required for reliability.
- Get multiple quotes from independent shops versus dealership service departments.
- Coordinate the service with other planned maintenance to reduce labor repetition (for example, if you’re already doing a valve cover job or ignition service).
- Inquire whether a bundled price is available for parts plus labor, and ask about any ongoing promotions or coupons.
Even when you’re shopping for price, balance cost with reliability. Using OEM-recommended plugs and a reputable technician helps ensure the job lasts and you won’t incur returns for misfires or leaks soon after service.
Getting a quote
To obtain an accurate figure for your specific Explorer model and engine, contact local shops with the following information: model year, engine type, current mileage, and whether you want OEM or aftermarket plugs. Request a written estimate that itemizes parts and labor, and ask if they’ll confirm that ignition coils or boots aren’t needed before starting work.
Summary
Spark plug replacement on a Ford Explorer generally falls in the $200–$500 range, with four-plug engines tending toward the lower end and six-plug engines toward the higher end. The exact price depends on engine type, plug selection, labor rates, and accessibility. Always compare multiple quotes and confirm what’s included (parts, labor, and any potential coil replacements) before proceeding. Regular maintenance and choosing the right plug type for your engine can help maximize reliability and minimize future service costs.
When to replace spark plugs on a Ford Explorer?
When it comes to changing spark plugs in your Ford vehicle, Yorktown drivers often wonder about the ideal frequency. While experts generally recommend replacement every 30,000 miles, the specific interval may vary depending on your model.
What year do Ford's have the spark plug problem?
If you are the owner of a Ford truck with a three-valve (3V) modular V-8 or V-10 engine built from 2004 thru 2007, you have either faced the misery of broken spark plugs-or you will.
How much does it cost to replace spark plugs on a Ford Explorer?
The cost to replace the spark plugs on a Ford Explorer can range from approximately $200 to over $850, depending on the model year and engine type. Factors like the specific model, the cost of parts, and whether you use an independent shop or a dealership will influence the final price, with dealerships generally costing more.

Factors that influence the cost
- Model Year and Engine: Newer models and engines, especially those with turbochargers or hybrid systems, often have higher labor costs due to complexity. For example, a 2019 V6-3.5L Turbo engine has a high cost, while an older 2010 V6-4.0L engine is on the lower end.
- Labor Costs: The time it takes to replace spark plugs varies significantly. Some engines require removing more components, which can increase the labor time and cost.
- Parts: The price of the spark plugs themselves can range from around $5 to over $15 per plug, depending on the brand and type (e.g., platinum, iridium).
- Type of Shop: Dealerships typically charge higher labor rates and use OEM parts, which can make their service more expensive than an independent mechanic.
Example price ranges
- Independent Shop: Often quoted between $300 and $500, depending on the complexity of the job.
- Dealership: Prices can range from $300 to over $850 for more complex models.
Why is changing spark plugs so expensive?
Spark plug replacement is expensive due to factors like increased labor, the cost of premium plugs, and the need to replace other parts at the same time. Engine design often makes plugs difficult to access, requiring technicians to remove other components like intake manifolds, which significantly increases labor time and cost. The materials in modern, high-performance plugs like iridium and platinum are more expensive than basic copper plugs.

Labor costs
- Difficult access: Many modern engines bury the spark plugs under other parts, requiring extra steps like removing the intake manifold or engine covers.
- More parts to remove: Some vehicles require removal of components like the exhaust manifold or ignition coils, adding to the time and complexity of the job.
- Time: The increased labor time directly translates to higher labor charges, as mechanics often charge by the hour.
Parts costs
- Premium materials: Modern vehicles often use high-performance spark plugs with iridium or platinum tips, which are more durable and efficient but cost more.
- Specialized plugs: Some vehicles require specific, specialized plugs for optimal performance, which can be more expensive to manufacture and purchase.
- Ignition coils: It is common to need to replace the ignition coils or spark plug wires along with the plugs, adding to the total parts cost.
Other factors
- Engine size: A larger engine with more cylinders (e.g., a V8) will have more spark plugs to replace, increasing both parts and labor costs.
- Part quality: The brand and quality of the spark plugs and other components can influence the final price.
