Spark Plug Replacement Cost
Spark plug replacement costs can range all the way from $2-$100. The prices ultimately depend on the type of spark plugs needed and labor charges. For example, standard copper spark plugs cost $2-$10 each, while iridium plugs can cost up to $100 each.
How Much Does Spark Plug Replacement Cost?
As mentioned, replacement costs for spark plugs will vary widely. Labor charges will differ based on the complexity of each engine. For example, V6 and V8 engines cost much more than four-cylinder engines. The average labor charges will come in between $40-$350.
It’s recommended to replace all the spark plugs at the same time to avoid dealing with different replacement cycles, helping to achieve optimal performance. In addition, replacing spark plug wires, coil pack, fuel filter, and oxygen sensor can impact the overall performance of the spark plugs. An old fuel filter can cause buildup of carbon and oil around the plugs. This will dull their effectiveness.
Here are the average prices of common spark plug types:
- Standard copper spark plugs: $2-$10 each.
- Silver spark plugs: $5 each.
- Platinum and double platinum spark plugs: $10-$20 each.
- Iridium plugs: $20-$100 each.
When you factor in both parts and labor for this replacement, the service will cost anywhere from $100-$500, with an average of $300, according to JDPower.
When To Replace Your Spark Plugs
The frequency of spark plug replacements will depend on the type and maintenance needs. Automakers recommend replacing these plugs every 30,000-40,000 miles. Platinum-tipped spark plugs should be replaced every 60,000 miles, while iridium plugs need to be replaced between every 100,000-120,000 miles.
Let’s take a look at a few signs of worn-out spark plugs, prompting the need for replacements.
Hard To Start Vehicle
The spark clause could be the issue when a vehicle is struggling to start up. Even with a good battery, your engine will have to work harder to make up for weak plugs. In some cases, the vehicle will not start up because the plugs don’t generate enough spark to turn the engine over.
Slow Acceleration
The vehicle fails to respond to the throttle when accelerating or struggles to pick up speed. This is the time to inspect the spark plugs.
Rough Idling
The engine emits a knocking and rattling sound when idling or loud noises emanate from the engine due to the added strain on your engine cylinders.
Less Efficient
Since there is no effective fuel or air mixture combustion, the engine will suck more fuel into the combustion chamber. This will make the vehicle run correctly, which results in poor fuel economy.
Engine Misfires
Overworked spark plugs often lead to engine misfires. Misfires can lead to the transfer of raw fuel into the exhaust due to incomplete combustion, which is a source of catalytic converter issues.
