In most Honda vehicles, spark plugs cost roughly $2 to $40 per plug depending on material, with a complete replacement typically ranging from about $100 to $300 including labor. Exact pricing depends on engine type, plug brand, and local shop rates.
Plug types and price ranges
Prices vary by the plug material and brand. Here’s a quick guide to typical single-plug prices you’ll see when shopping for a Honda.
- Copper core plugs: about $2–$6 each; the least expensive option, often found on older Hondas.
- Platinum plugs: about $8–$15 each; common in many newer Hondas for longer life.
- Iridium plugs: about $15–$40 each; higher-performance and longer-life option used on some modern engines.
- OEM vs aftermarket brands: NGK and Denso are common OEM suppliers for Honda; price varies by brand and retailer, with OEM sometimes commanding a small premium.
Most Honda four-cylinder engines use four plugs; six-cylinder models use six. Engine access and the number of components to remove can influence the total price beyond the plug cost.
How many spark plugs does a Honda engine have?
4-cylinder Honda engines
Most Honda passenger cars with four-cylinder engines have four spark plugs.
6-cylinder Honda engines
Most Honda V6 engines use six spark plugs. Some modern engines or hybrid configurations may have additional coil-on-plug arrangements, but the standard count is six for a typical V6.
Estimated replacement costs
When you factor in parts and labor, here’s a rough range you can expect for a standard 4-cylinder Honda. Prices vary by region and shop rate, and the exact number of plugs matters for total cost.
- 4-cylinder, copper plugs: parts about $8–$24; labor about 0.5–1 hour; total roughly $40–$140.
- 4-cylinder, platinum plugs: parts about $32–$60; labor about 0.5–1 hour; total roughly $70–$190.
- 4-cylinder, iridium plugs: parts about $60–$160; labor about 0.5–1 hour; total roughly $100–$260.
- 6-cylinder, copper/platinum/iridium: expect labor to be 1–2 hours; total ranges scale up by roughly $50–$150 depending on labor rate.
Note that performance-tuned models or engines with restricted access can push labor times higher, and some Hondas use coil-on-plug systems that affect replacement steps and cost.
Where to buy and how to save
Where you buy and how you shop can influence final costs. Here are common options and money-saving tips.
- Auto parts stores: National chains typically stock NGK and Denso plugs used on Hondas; look for promotions or member discounts.
- Online retailers and parts aggregators: Often cheaper per plug, with bundle deals for sets of four or six.
- Dealership parts counters: Reliable OEM fit but typically pricier; sometimes promotions offset the cost.
Saving tips include buying in sets that match your engine's plug count, checking for four-pack or six-pack deals, and confirming the correct heat range and gap specification for your specific Honda model before purchasing.
Summary
Spark plug prices for a Honda range from a few dollars per plug for copper units to up to around $40 or more for iridium plugs. A typical four-cylinder replacement (parts and labor) generally sits in the $40–$190 range, while six-cylinder engines run higher due to more plugs and longer labor time. Always verify your exact engine type and plug count, buy from reputable brands, and budget for labor based on local rates. Regular replacement helps maintain fuel efficiency and smooth operation.
