Spark Plug Replacement Cost

No Comments

Spark plug replacement costs can vary widely, ranging all the way from $2-$100. Total costs depend on spark plug types and labor charges. Standard copper spark plugs, for example, cost only $2-$10 each. Iridium plugs cost up to $100 each.

Average Cost Of Spark Plug Replacement

With a wide range of costs for spark plug replacements, labor charges can ultimately make a big difference for the total bill. V6 and V8 engines will cost much more than four-cylinder engines when it comes to labor. Most labor charges will fall between $40-$350 overall.

The auto care professionals recommend replacing all spark plugs at the same time. This helps to avoid different replacement cycles, which can result in achieving optimal performance.

Additionally, the replacement of coil pack, spark plug wires, and oxygen sensor can impact the performance of your spark plugs. Oil fuel filter may cause buildup of both carbon and oil around the plugs. This dulls their overall effectiveness.

These are the common prices of 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 spark plugs: $20-$40 each.

When To Replace Your Spark Plugs

The frequency of this replacement will depend on type and maintenance needs of the vehicle. Automakers generally recommend replacing the plugs every 30,000-40,000 miles. Platinum-tipped plugs only need to be replaced once every 60,000 miles. Iridium plugs should be replaced every 100,000-120,000 miles.

Here are a few signs that you need to replace your spark plugs:

Slow To Accelerate

It’s time to get your spark plugs looked at whenever the vehicle fails to respond to the throttle when accelerating.

Hard To Start Car

If the car fails to start, it’s possible that worn out spark plugs are the root of the cause. Even with a new battery, the engine must work harder when weak plugs are present. The car may not start up at all if the plugs fail to generate enough power to turn the engine over.

Less Efficient

The engine will suck more fuel into the combustion chamber when there is no effective air or fuel mixture combustion. This can result in poor fuel economy.

Engine Misfires

Overworked and worn out spark plugs can cause the engine to misfire at times.

Rough Idling

If the engine emits a knocking or rattling sound when idling or you hear loud noises coming from the engine, it’s time to have your spark plugs inspected.
