If you are using more gas than usual, losing power or have a rough running engine, worn or dirty spark plugs could be the problem.
Spark plugs create a high voltage spark that ignites the air and fuel mixture in the cylinders. They are part of the ignition system which has many components including the generator, coils, wires and the engine computer. All these components need to be working in harmony to achieve maximum power and fuel efficiency.
If your engine is running rough or is hard to start you should have your vehicle checked as soon as possible. A flashing Check Engine light is another sign that you may have a bad plug. This light will flash if there is an excess amount of unburned fuel in the exhaust.
Driving a poorly running vehicle can also lead to overheating and major engine damage.
How Often Should Spark Plugs be Replaced?
Years ago, spark plug maintenance was a yearly ritual. Because of improved spark plug design, the use of unleaded gas and modern engine technology, spark plugs can last up to 100,000 miles.
For most cars, the average life expectancy of spark a set of spark plugs is 30,000 až 60,000 XNUMX mil. Many factors can cause premature spark plug failure. Hard driving, towing, stop and go driving or poor gasoline quality can all cause spark plugs to fail prematurely.
Follow your owner’s manual for the recommended service interval for your specific vehicle, or ask your dealer Service Department Manager.
What is the Cost To Replace Spark Plugs?
The average cost to replace all the plugs in an average four-cylinder vehicle is between $200 to $300 dollars. The cost can increase significantly if your vehicle has a six, or eight-cylinder engine.
Some vehicles have hard to reach spark plugs, and it may be necessary to remove manifolds and other components to reach the plugs which adds to the labor cost.
If a vehicle has more than 50,000 miles other components may need replacement which can add to the overall cost. These can include spark plug wires, coils, or even engine repairs.

Pokyny krok za krokem
Start with the engine cold.
The first step is to pop the hood and prop it up. I’ll often spread a rag over part of the engine bay to set tools and parts. Use your preferred method.
Use a 10 mm socket wrench to remove the 4 nuts holding down the spark plug cover.
Then remove the plastic cover.
This will expose the spark plug boots. Remove the 10mm bolts holding those down.
Press the tabs on the sides of the plastic connectors, to remove the wires from each ignition coil boot.
Then, carefully grasp the boot and pull it upward, unseating it from the spark plug. You will likely hear a suction sounds as the connectors comes loose from the top of the spark plug, this is normal.
If the ignition coil boot is damaged, or replacing the spark plugs doesn’t fix your rough idle or misfiring, consider replacing these ignition coils. Here is the link for the correct parts (set of 4).
Now you will be able to see down into the bore, where the top of the old spark plug is. Use a 5/8″ spark plug socket and an extension on your socket wrench.
Update: This tool will make it a lot easier. Instead of duct tape and the old rubber boot (that never seems to work) this one uses a magnet – a no-brainer – to hold the spark plug in place!
Slide this down into the bore and get it seated onto the old spark plug. Turn counter clockwise to loosen and remove the old plug. Be very careful not to drop anything down into the hole. Sand blowing around, for example, would be very bad for your engine, so take care and cover the holes with a rag, if necessary.
Once the old plugs are removed, inspect them. Things that indicate the plugs should be replaced include, carbon buildup, too large gap, corrosion, damage of some sort, etc…
Spark plugs, even good ones, are so cheap that even if you don’t notice anything obviously wrong with them, you may as well change them if you have gotten to this point. But if you’re short on money at the moment, just make sure there are no obvious problems.
Here is a picture of the old and new spark plug side by side, for reference.
You are now ready to put in the new plugs. I’ve always gone with the Denso plugs and they’ve worked great for me. The gap is already set, so you don’t have to adjust it.
If you really want to do this right, put some dielectric grease on the ceramic parts of the new plugs to reduce the chance of moisture interfering with the connection. Don’t get it anywhere near the gap.
Also, put some anti-seize in the threads as well. This will make your life easier the next time you do this, and it will make it less likely that you strip the threads in the bore. You DO NOT want to strip or cross thread the threads in the bore!
Also, the spark plugs come with a crush gasket. This is intentional, leave these on. They set the correct distance into the cylinder and assure a proper fit.
Now, use a torque wrench (this is the torque wrench I use), extension, and 5/8” spark plug socket to put in the new plugs.
Torque the plugs to 13 ft-lbs. (If you don’t have a torque wrench, follow the instructions on the box, it will usually tell you to tighten by hand, then another 1/2 turn it so.)
Put the boots back on each plug and press down on them firmly so that they seat nicely in the top of the plug.
Put the 10 mm bolts back in to hold the boots in place, then re-attach the plastic wire connectors. Just press those in, and they will click into place.
Now put the plastic cover back on and tighten up the 4 10 mm nuts that hold the cover down.
That about wraps it up. Thanks for visiting, and I hope you found this helpful!
