Apart from how expensive or exquisite your car is that would push the labor charges towards the high side. There is one more reason that can push the labor charges on the higher side, and that is how much time and effort would it require to reach out to the places where spark plugs are installed. Scenarios where mechanic has to to take off the motor mounts to rock the engine. In some makes raisng an engine might required to replace the plugs.

Dealer vs Independent Mechanic

A dealer would usually be atleast a $100 pricey in compare to a mechanic. Its worth it to research and find a good mechanic as it can save you some cost. If no well recommended mechanics are available or you want to keep your warranty intact, its recommended to stick with a dealer, even if they charge sligthly higher.

Type of Spark Plug

Go for the manual recommended spark plug for your vehicle. Your mechanic or dealer would be able to specify what type of spark plug would suit you best. There are three main types of spark plug

  • Copper – They are used in the older cars, and are cheaper than the other spark plugs. Please note new cars do not use these types of spark plugs any more and are usually going to use a superior technology. Reason being these copper, or nickel based spark plugs will get you under 25,000 miles and afterward will require a replacement.
  • Platinum – A more durable version of a spark plug and is charged almost thrice the price of a copper spark plugs, and data shows that it is more than likely to last for around 75,000 miles or more. These are now the commonly used spark plugs in modern vehcles.
  • Iridium – The are long lasting, and require less current to start the car. They have a longer life, and will last you for around 90,000 miles or more.

In terms of costing, you might be hearing that iridium costs more than copper spark plugs, in my expereince thats wrong, if you know the right places you will be able to source any type of these spark plugs at around $7 to $10, buying in packs of 4 would get you a better deal in most cases as well. I would also suggest don’t go for unknown manufacturers for saving a few bucks, go for reputable brands only.
