The short answer: replacing all six spark plugs on a 2013 Honda Pilot typically costs about 200 to 450 dollars, depending on plug type and local labor rates. Dealers tend to be higher, while independent shops are usually lower.
In more detail, the 2013 Pilot uses a 3.5-liter V6 engine with six spark plugs. The total price is driven by the type of plugs you choose (copper, platinum, or iridium), how long the mechanic must spend accessing the plugs, and regional labor rates. Copper plugs are cheapest but wear faster; iridium or platinum plugs cost more upfront but typically last longer. Accessing the plugs on this engine is moderately labor-intensive, so labor costs can form a large portion of the bill. If additional items (such as ignition coils, an oil change, or a diagnostic) are performed at the same visit, that can also affect the total.
What goes into the price
Costs can be broken into three main components.
- Parts: Six spark plugs. Copper plugs are the least expensive option, while iridium or platinum plugs carry a higher upfront price but longer life. For six plugs, expect roughly:
- Copper equivalents: about $12–$24 total
- Iridium/platinum equivalents: about $60–$120 total
- OEM or branded plugs: commonly in between or higher depending on the brand
- Labor: Accessing and replacing six plugs typically takes about 1.5 to 2.0 hours, depending on shop setup. At typical labor rates of roughly $90–$150 per hour, you’re looking at about $135–$300 in labor.
- Additional charges: Some visits include or add on items like ignition coils, a misfire diagnostic, an oil change, disposal fees, or small shop charges. These can add roughly $10–$60 or more to the bill, depending on what’s performed.
Overall, most customers can expect a total in the broad range of $200 to $450, with dealership pricing often toward the higher end and independent shops toward the lower end. The exact amount hinges on plug type, regional labor rates, and any extra services performed at the same time.
Plug types and price impact
Choosing the plug type affects upfront cost and maintenance intervals. Here’s how they typically compare.
Copper plugs
Cheapest upfront. Lifespan tends to be shorter, often around 30,000 to 60,000 miles depending on driving conditions. Some drivers opt for copper plugs when the manufacturer does not specify iridium or platinum, but many modern Honda engines benefit from longer-life options.
Iridium or platinum plugs
Higher upfront cost but longer service life, commonly around 60,000 to 100,000 miles with proper maintenance. Widely recommended for modern engines, including many Honda designs; many 2013 Pilot owners choose iridium or platinum plugs for fewer replacements and steady performance.
Always verify the manufacturer’s recommendation for your engine and model year before buying parts.
Summary
For a 2013 Honda Pilot, replacing all six spark plugs generally costs between $200 and $450, influenced by plug type, labor rates, and any additional services performed during the visit. Independent shops typically offer lower prices than dealerships, and you can save money by choosing the appropriate plug type for your driving needs and by comparing quotes from nearby shops. Planning ahead and using the manufacturer-recommended parts helps ensure reliable engine performance and value over time.
