How much does it cost to replace spark plugs in a Ford F-150?
Expect roughly $200 to $550 for a spark plug replacement on a Ford F-150, depending on engine type and local labor rates. The exact price varies with which engine your truck has, the spark plug type, and whether you choose a dealership or an independent shop.
To understand the pricing, it helps to break down the factors involved: engine configuration (six-cylinder vs eight-cylinder), spark plug type (copper, platinum, or iridium), labor costs, and regional pricing differences. This article covers current price ranges and practical considerations for F-150 owners as of 2025.
Engine options and spark plug counts
The F-150 comes with several engine choices, and the number of plugs depends on the cylinder count. The following estimates assume standard coil-on-plug ignition and typical replacement practices.
- Six-cylinder engines (such as 2.7L EcoBoost, 3.5L EcoBoost, and 3.3L Ti-VCT V6) usually require six spark plugs. Parts cost for a full six-plug set is typically about $40–$120, depending on plug type and brand. When you include labor, total replacement cost commonly ranges from about $190–$545.
- Eight-cylinder engines (the 5.0L V8) use eight spark plugs. Parts cost for eight plugs is typically about $60–$160. With labor, total replacement cost commonly ranges from about $210–$585.
These ranges reflect a mix of copper, platinum, and iridium plugs, as well as variations in shop labor rates. In practice, the bigger driver is usually labor time, not just the price of the plugs themselves.
What drives the price?
Several factors influence the final bill beyond the number of plugs. Understanding these helps you estimate and compare quotes from shops.
- Plug type and number: Copper plugs are cheaper, while platinum and iridium plugs cost more upfront. A six-plug set typically costs less than an eight-plug set, but iridium variants push prices higher for both configurations.
- Labor rates and time: Labor costs vary widely by region and shop type. Typical hourly rates range from roughly $100 to $180 per hour, and replacement time is about 1.5–2.5 hours depending on engine and access.
- Dealer vs independent shop: Dealerships often charge higher labor rates and may recommend OEM parts, while independent shops can offer lower rates and generic or OEM-appropriate parts.
- Additional work: If ignition coils, wiring, or intake components must be removed to reach plugs, labor time increases and the total price can rise.
In most cases, labor constitutes a larger share of the cost than the parts themselves, especially on modern coil-on-plug setups where plug access can be time-consuming.
DIY vs professional replacement
Replacing spark plugs yourself can save labor costs, but it requires the right tools and some mechanical experience. If you do it yourself, you’ll primarily pay for parts and basic tools (spark plug socket, extension, torque wrench, and lubricant or anti-seize as recommended by Ford). Professional service adds the benefit of torque accuracy, coil inspection, and a guaranteed install.
- Do-it-yourself cost: Parts only, typically $40–$170 depending on engine and plug type, plus tool costs if you don’t already own them. Time investment and the risk of cross-threading or damaging delicate ignition components are the main caveats.
- Professional replacement: Convenience, proper torque and gap checks, and a warranty on labor. Expect the higher end of the ranges above, especially in urban or dealer settings.
DIY savings can vary widely, but many owners save a few hundred dollars compared with dealer pricing, especially when dealing with multiple plugs and newer, iridium-type plugs.
Summary
For most Ford F-150 configurations, plan on roughly $190–$545 for a six-plug replacement and $210–$585 for an eight-plug replacement, including parts and labor. Costs fluctuate with engine type (six-cylinder vs eight-cylinder), plug material, regional labor rates, and whether you use a dealership or an independent shop. If you’re comfortable with basic auto work, replacing plugs yourself can cut costs further, but ensure you follow Ford’s torque specs and service guidelines to avoid misfires or damage.
Notes for readers
Prices cited reflect typical market ranges in 2025 and may vary by region, shop, and part supplier. Always obtain a written estimate that itemizes parts, labor, and any additional services before authorizing work.
Bottom line
Whether you choose to go with a dealer or an independent shop, the spark plug replacement on an F-150 is a routine maintenance job with costs largely driven by engine type and labor rates. Being aware of plug counts and potential extra labor helps you make an informed choice and compare quotes accurately.
