Spark plugs ignite the fuel mixture and wear out as the electrode erodes. Copper plugs last around 30,000 miles, while iridium and platinum plugs often reach 100,000. Labour varies enormously: some four-cylinder engines are a twenty-minute job, while some V6 layouts need the intake manifold removed to reach the rear bank.
A single national average hides the thing you actually want to know, which is whether your car sits at the cheap or expensive end. Usually it is access rather than the part that moves the price: the same component can take an hour on one engine layout and most of a day on another.

The ranges above cover a spread of vehicles. Enter a VIN and the report gives the estimate for that exact year, make, model and trim, alongside what the car has actually been through: accidents, title brands, odometer readings and open recalls.
Worn plugs make the coils work harder, and a persistent misfire dumps unburnt fuel into the exhaust, which is what destroys catalytic converters. Replacing on schedule is far cheaper than the knock-on damage.
Expect $193–$645 in total: $77–$322 for parts and $116–$323 for labor. Figures are drawn from 20 popular vehicles, so your car may sit at either end.
Rough idle or a stumble under acceleration. Harder starting, particularly in cold weather. A misfire code on the diagnostic reader. Fuel economy drifting down over months.
Access is usually the reason rather than the part itself. Across the vehicles we sampled, a 2008 Ford Escape comes to $193–$260 while a 2017 RAM 1500 comes to $474–$644 for the same job.
Enter your VIN. The report includes the repair cost estimates for that specific year, make, model and trim, alongside its history: accidents, title brands, odometer readings and open recalls.
About these figures. Parts and labor ranges are supplied by a licensed vehicle-data provider and reflect a sample of 20 popular vehicles as of 2026-09-17. They are estimates for comparison, not quotes. What you actually pay depends on your vehicle, your local labor rate, whether the shop fits original-equipment or aftermarket parts, and what else is found once the job starts.
