Advantages of Spark Plug

01/

They help provide the necessary ignition to the air and fuel mixture in the cylinders.

02/

They help maintain the correct timing between the opening and closing of the valves.

03/

Spark plugs help reduce fuel consumption by up to 15%.

04/

They also help limit emissions from the engine by up to 30%.

05/

Spark plugs help improve the performance of the engine by providing better combustion.

06/

They also help extend the life of the engine by preventing pre-ignition and knock.

Spark Plug Materials

Copper: These spark plugs feature a center electrode that has a copper core coated with a nickel alloy. These are inexpensive, but not widely used today since they aren’t very durable.

Platinum: These are similar to copper plugs, but the center electrode (and sometimes the ground electrode) use platinum. They are more durable and allow for a longer lifespan.

Iridium: These are the longest-lasting plugs and are more heat-resistant than platinum. These plugs also use a small center electrode, which requires less voltage to generate a consistent spark.

Ruthenium: This is one of the newest precious metals to be used in spark plugs. They claim improved durability over iridium but carry a higher price tag.

Silver: These plugs feature silver-coated electrodes and may be seen in some performance applications. They aren’t very common, since they are costly yet not as durable as platinum or iridium.

Spark Plug Replacement Steps

Gather the Necessary Tools
Changing a spark plug requires at least the following tools:

A special socket that is deep enough to accommodate the plug
An interior rubber gasket that protects the tip of the plug from damage
A spark-plug gapping tool to check the spacing between the electrode and the ground strap against your vehicle’s specifications

Make Sure the Engine Is Cold
A hot engine can burn your skin. On top of that, changing a spark plug with a warm engine head can damage the threads that hold it in place.

Disconnect the Battery
When working on any aspect of an engine’s electrical system, it’s always a good idea to disconnect the battery terminals to prevent accidental short circuits.

Remove Spark-Plug Wires or Coil-On-Plug Connectors
Older vehicles use spark-plug wires that connect them to the ignition system. Many newer models rely on a coil-on-plug design, which gives each individual spark plug its own ignition coil. Regardless of the design on your vehicle, each must be removed prior to replacing your spark plugs.

Remove Spark Plug With Socket
Fit the spark-plug socket over the protruding plug and gently unscrew it from the engine using a counter-clockwise motion. Too much force can crack the plug and cause pieces to fall into the engine. Do your best to ensure no debris enters the spark-plug hole when you lift it out.

Examine the Spark Plug
By determining the condition of the spark plug you’re changing out, you can gain insight into how your engine is performing and help diagnose any potential problems.

Install New Spark Plug
Thread a new spark plug into the cavity where you removed the old one, being careful not to cross-thread or force in the plug. Screw it in until finger tight, then use your socket to give it another half-turn. With most brands of spark plugs, rubbing a little anti-seize lubricant on the threads can help ensure that the spark plugs will be easy to remove the next time.

Reattach Wires / Coil-On-Plug Connectors / Battery
Wrap up your installation by reinstalling the vehicle’s spark-plug wires or coil-on-plug connectors in the correct order, and then reconnect the battery.

FAQ

Q: What to do after installing new spark plugs?

A: After replacing spark plugs, it's important to check for proper installation and address any potential issues. Ensure the spark plugs are tightened to the correct torque, and the wires or coils are securely connected. Start the engine and observe for any misfires or unusual noises. If a misfire occurs, re-check the spark plug installation, including the gap, and inspect the ignition wires or coils.

Q: Do I need a hotter or colder spark plug?

A: There is no real danger with going colder than required. The only downside is that a colder plug is more prone to fouling. This is made worse if you aren't regularly giving the engine a decent amount of load and getting the plugs hot enough to burn off any contaminants.

Q: Is spark plugs an easy job?

A: While changing spark plugs is a relatively straightforward task, success can depend on your vehicle's design and your comfort level with tools. If you follow the instructions carefully, you can likely complete the task without prior experience.

Q: How long do spark plugs last?

A: Spark plug lifespan varies depending on the type and driving conditions, but generally, they should be replaced every 30,000 to 100,000 miles. Conventional copper spark plugs typically last 20,000 to 30,000 miles, while platinum and iridium plugs can last 60,000 to 100,000 miles or more.

Q: Do spark plugs add horsepower?

A: Spark plugs themselves don't directly increase horsepower. Instead, they ensure the engine is operating at its optimal performance level by properly igniting the air/fuel mixture. If your existing spark plugs are worn out, fouled, or not functioning correctly, replacing them with new, properly gapped plugs can restore lost power and improve efficiency.

Q: Is there a break-in period for spark plugs?

A: No, spark plugs do not have a specific break-in period. They are ready to perform optimally as soon as they are installed correctly. However, some initial fouling from lubricants used during installation might occur, but this typically clears up quickly after a short drive.
