FixChevrolet Silverado 1500 — Spark Plugs Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $220 – $591. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
Cost by model year
Newer model years cost more: the newest group runs about 2 times the oldest. If your quote is for a car in one of these groups, compare it with that row. Middle half of real Chevrolet Silverado 1500 invoices for each group, parts + labor:
| Model years | Typical cost | Median |
|---|---|---|
| 2004 and older | $195 – $446 | $315 |
| 2005–2009 | $209 – $516 | $358 |
| 2010–2014 | $198 – $590 | $369 |
| 2015–2019 | $360 – $728 | $527 |
| 2020 and newer | $498 – $856 | $642 |
Real repair reports
These reports are a recent sample of real, paid Chevrolet Silverado 1500 spark plug replacement visits — quoted the way the owner and the technician actually said it.
Car owners said
“Misfire diagnostics and repair-replace all spark plugs”
“Customer states vehicle has multiple miss fires. diagnose and replace spark plugs as needed”
“Install customer's spark plugs”
“Diagnose check engine lite”
“Spark plugs and diff and t-case services”
“Spark plugs/ fuel inducton service”
What this repair is
Spark plugs ignite the fuel in each cylinder. Worn plugs cause rough running, misfires, poor fuel economy, and eventually a flashing check-engine light. Modern plugs last 60k–100k miles; the price is mostly labor, which varies hugely by how buried the plugs are on your engine.
Is your quote fair?
If your quote lands between $220 and $591, it's inside the range where half of all real Chevrolet Silverado 1500 repairs of this kind land — and the typical job takes about 2 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
