When Should I Replace My Spark Plugs?

Cars have come a long way over the years, but the maintenance component of owning a car is relatively the same. After you have driven your car a certain number of kilometers there are various recommendations that are made by the manufacturer. These may include the brakes, engine, or spark plugs.

Spark Plug Wear

Like other components of your engine, spark plugs wear out over time. The main reason for wear is typical with the electrode. If you look at a spark plug, you can notice one end is narrow and tapered – this is where the wire connects. The other end is bulbous, with a small metal rod coming out of the center, and a metal hook to one side. Normal use will cause the electrode on each spark plug to wear down. This causes the electrode to become worn, not creating any or minimal electric spark, which has a direct effect on the way the engine will operate.

When to Replace Spark Plugs

Many automakers recommend you replace the spark plugs in your vehicle around every 100,000 kilometers. Depending on your the way you drive your vehicle or the spark plugs that are in your Honda, this timeline may vary depending on these factors:
High Performance: if your vehicle contains high-performance spark plugs, it may be possible you will need to replace them more often.
Long Life: Select spark plugs are made to have a longer life. This means that the electrodes are not to wear down as quickly, meaning you should not have to replace them as frequently.
Oil Leaks: when you take your spark plug out, the base should be relatively clean. If there is oil, this means there is a leak. Not only will you need to replace the blown seal to stop the oil leak, but you will need to change your plugs more frequently because of contamination.
High Revs: High revving of your car puts additional wear and tear on your spark plugs, meaning you will need to replace them more frequently.

Additional Pointers

When you take your car for its regular maintenance check, it’s always good to have your spark plugs checked. Having your mechanic check these will save you a headache, especially if you’re not sure what to look for. It’s always a good idea to check a few other things under the hood when it comes time to change your spark plugs:

  • Air filter
  • Cabin air filter
  • Belts and hoses
  • Charging system
  • Starter
  • O2 sensor
  • All vacuum lines and junctions
