How frequently should spark plugs be changed?
In general, you should replace your spark plugs at the intervals recommended by your car’s owner’s handbook, which is normally around 30,000 miles. It’s time to change your spark plugs if your owner’s handbook doesn’t tell you when to replace your old ones with new ones, if you don’t know when someone last installed spark plugs in your new car, or if you’ve seen any symptoms of a malfunctioning spark plug.
The spark plugs are the first item you should check if anything about your engine feels off. Check the location of the spark plugs in your automobile using the owner’s manual or a car finder, then look under the hood to see what’s going on for yourself. If your spark plugs appear to be dusty, you may have carbon buildup or an oil leak. If your spark plugs are worn or broken, your engine may be misfiring or operating at an excessively high temperature.

A Prius hybrid has spark plugs, right?
Yes, the Toyota Prius has spark plugs, and they must be replaced. The issue is when. In this piece, I’ll respond to that and explain how to tell.
Spark plugs are frequently mentioned but not extensively. We may all agree that they need to be changed, but the questions of when and how frequently confuse many Toyota Prius owners.
Spark plugs made of iridium are included with the Toyota Prius. A high melting point leads into higher performance and perfect combustion, among other advantages. These are all valid reasons why Iridium spark plugs are used in Prius (and many other vehicles), but there is one more compelling one: lifespan.
An iridium spark plug has a 100,000 mile lifespan on average. According to NGK, the lifespan of their Laser Iridium plugs is between 80 and 100k miles. In any event, Toyota recommends changing your plugs every 90k miles, or around the “major service interval.”
I frequently receive this query from Prius owners. Here is a handy tip if you are unsure if your spark plugs are original or not.
The very tip of original equipment, or OE, plugs is marked with a small white dot. There is a chance that those plugs are original if this dot is present. They may need to be changed based on the car’s mileage.
Unlike engine oil, spark plugs may sit for a lot longer while still functioning. It’s best to inspect inside the spark plug tubes to see if there has been any rust buildup if you reside in a region with high humidity and the car has been sitting for a while.
The terms “leaking spark plugs” and “soot-coated spark plugs” should also be mentioned. A spark plug needs to be replaced if it is leaking. The ceramic component of a leaking spark plug will appear like it has rust on it in the image below. These plugs need to be changed because of blow-by.
