How much does it cost to replace spark plugs on a Honda Accord?
Typically, a spark plug replacement at a shop costs about 150 to 300 dollars for a Honda Accord.
DIY costs can be much lower if you provide the parts and have the right tools, but you’ll still need to budget for the plugs and any specialty tools needed for access and torque. This article explains the factors that influence price and provides current ranges for the main Accord engine options as of 2025.
What drives the cost
Several factors influence the final bill. Here are the main ones to watch when budgeting for a spark plug replacement:
- Engine type and accessibility: Accord models come with different 4‑cylinder engines (including 1.5L turbo and 2.0L turbo) and a hybrid option. Plug accessibility and labor time vary by engine, which affects pricing.
- Spark plug type and price: Copper plugs are cheaper but wear faster; platinum or iridium plugs last longer and are often required by newer engines. OEM vs aftermarket plugs can shift price significantly.
- Labor rates and time: Regional labor rates differ widely. A typical 4‑cylinder spark plug job ranges from about 0.9 to 2 hours in shop time, influencing the total labor portion of the bill.
- Additional services: If ignition coils, coil boots, or coolant-related work are needed, the price can rise beyond a basic plug replacement.
- DIY vs professional: Doing it yourself saves labor costs but requires the right tools and know‑how; mistakes can lead to engine misfires or damage.
Understanding these factors helps you compare quotes and decide whether to tackle the job yourself or hire a pro.
Typical price ranges by engine type
Here are typical ranges you may see for common Accord configurations in 2025, broken down by engine option and including both parts and labor:
- 1.5L turbo (most common 4‑cylinder): Parts for four iridium/platinum plugs typically run about $40–$80; labor is commonly around $100–$180. All‑in, expect roughly $140–$260, though prices can climb in high‑cost areas or at dealer shops.
- 2.0L turbo: Parts for four plugs usually $60–$110; labor about $120–$210; all‑in around $180–$320.
- Hybrid Accord (2.0L Atkinson‑cycle with hybrid system): Parts $60–$100 for four plugs; labor often $150–$250 due to coil and system access; total around $210–$350.
Note that these ranges are approximate and depend on your vehicle’s exact year, plug type, and local labor rates. Always request a written quote before authorizing service.
DIY versus professional: what to consider
DIY replacements can save on labor but require the right tools, torque specs, and care to avoid cross‑threading or damage to ignition components. If you’re not comfortable with working under the hood or disconnecting components, a professional replacement remains the safer option and helps protect your warranty and engine performance.
Maintenance guidelines
Honda’s recommended replacement interval depends on plug type and engine. For most Accords using iridium or platinum plugs, replacement is commonly advised around 100,000 miles; copper plugs typically require more frequent changes (often 30,000–60,000 miles). Always verify the exact interval in your owner’s manual or with a dealer for your specific model year and configuration.
Summary
For most Honda Accord owners, plan for a replacement cost in the $150–$300 range when using a shop, with DIY parts-only costs potentially as low as $20–$100 depending on plug type and tool availability. Costs vary by engine, plug type, and regional labor rates, so obtaining multiple quotes and confirming the exact plug specification for your model year is advisable.
