How much does it cost to replace spark plugs on a 2017 Honda Civic?

Expect to pay about $150–$320 at a reputable independent shop in the U.S. or $230–$380 at a Honda dealership, as of 2025. DIY owners typically spend $40–$140 for a set of four iridium plugs, plus any tool costs. Final pricing varies by engine (1.5L turbo vs. 2.0L), local labor rates, parts choice (OEM vs. aftermarket), and shop fees and taxes.

What drives the price

Several factors influence the total you’ll see on an estimate or invoice. Understanding these variables helps explain why quotes can differ across shops and regions.

• Engine type: The 2017 Civic came with a 2.0L (K20C2) and a 1.5L turbo (L15B7); both use iridium plugs, but the turbo model’s parts and access can run slightly higher.
• Labor time and rate: Book time is generally 0.5–1.0 hour; shop labor rates commonly range $100–$180 per hour in 2025.
• Parts selection: OEM NGK/Denso iridium plugs usually cost more than reputable aftermarket equivalents.
• Regional costs and fees: Urban markets tend to charge more; shop supplies and environmental fees add a few percent.
• Condition-related add-ons: Seized plugs, damaged coil boots, or recommended intake/throttle-body cleaning can add time and cost.

Taken together, these factors usually keep most out-the-door totals within a predictable band, unless additional repairs are needed.

Typical price ranges by engine and provider

Here’s how common quotes break down for the two engines offered in the 2017 Civic, using current U.S. market rates.

• 1.5L Turbo (EX-T, Touring, some hatchback trims): Parts $80–$130; labor 0.7–1.0 hr ($90–$180) → Typical total $190–$330 at independent shops; $240–$380 at dealers.
• 2.0L Naturally Aspirated (LX, EX): Parts $40–$100; labor 0.5–0.8 hr ($70–$150) → Typical total $150–$280 at independent shops; $220–$340 at dealers.
• DIY: $40–$140 for a set of four iridium plugs (brand-dependent). Specialty thin-wall spark plug socket and a torque wrench may be required if you don’t already own them.

Quotes that land well outside these ranges often reflect extra work (like coil replacement) or unusually high shop rates; ask for an itemized estimate to verify.

Service interval and when to replace

Honda’s Maintenance Minder typically calls for spark plug service around 100,000 miles (often paired with code “4”), though the exact timing depends on the system’s algorithm and driving conditions.

• Replace at roughly 100,000 miles or when the Maintenance Minder calls for it.
• Earlier replacement may be warranted if you notice misfires, rough idle, sluggish acceleration, hard starts, or declining fuel economy.
• Both engines use long-life iridium plugs; gap is pre-set and generally should not be altered—follow service manual guidance.

Sticking to the recommended interval helps maintain performance, fuel economy, and catalytic converter health.

DIY vs. professional service

The job is straightforward for an experienced DIYer but benefits from the right tools and care. Consider your comfort level and the condition of the vehicle.

• Time: 30–60 minutes for a pro; about 60–90 minutes for methodical DIYers.
• Tools: Thin-wall spark plug socket, extensions, torque wrench, and a way to blow debris out of plug wells. Anti-seize is generally not recommended on plated iridium plugs unless specified by the plug maker.
• Technique: Work on a cold engine, replace one plug at a time, and torque to Honda spec from the service manual to avoid over-tightening or thread damage.
• Coils: Reuse unless cracked or misfiring; new coils add roughly $50–$120 each plus incremental labor.

If any plug feels abnormally tight, let a professional handle it to avoid cylinder head damage that can turn a small job into a costly repair.

How to get an accurate quote

Clear questions upfront lead to clearer, more comparable estimates across shops.

1. Ask for an itemized estimate showing labor hours, labor rate, parts brand/part numbers, shop fees, and taxes.
2. Confirm whether the quote uses OEM-equivalent iridium plugs (NGK or Denso are common OEM suppliers for Honda).
3. Request an out-the-door price and ask about any multi-service discounts if you’re bundling maintenance.
4. Clarify that ignition coils will only be replaced if testing shows a fault.

With this information, you can compare apples to apples and avoid surprise add-ons at checkout.

Bottom line

For a 2017 Honda Civic, most spark plug replacements fall between $150 and $320 at independent shops and $230 to $380 at dealers, with DIY parts typically $40 to $140. The 1.5L turbo tends to be on the higher side of the range, primarily due to parts cost and slightly longer labor. Staying on schedule—about every 100,000 miles—keeps the engine running smoothly and can prevent pricier issues down the road.
