Do you want to do it? It’s a hard decision. Toyota advises replacing the spark plugs every 90,000 miles. In most cases, that means you only perform it once over the car’s lifespan. However, it’s now far more expensive and less obviously important than it formerly was.
These days, spark plug failure is unusual. Spark plugs used to be changed every 12,000 miles, and they would have the appearance of having come from an arson crime scene.
Nowadays, plugs hardly ever lose their quality. They have an endless shelf life. Many vehicles with more than 100,000 miles on them with their original spark plugs are seen at the shop.
The risk, though, is that if they are never taken out, they can get caught in the engine. In a sense, they can fuse to the cylinder head. If a spark plug does ever fail, you’ll need to have your engine repaired severely and may have to spend hundreds of dollars to replace that particular spark plug.
In order to ensure that you could remove the plugs if necessary, you could simply loosen them and then tighten them again if they were easily accessible. You’d be stupid to put in all that time and not just change those plugs for the additional $81 considering how much effort it takes to reach the rear plugs on the RAV4.
So I have to advise you to change them as I’m a responsible mechanic and have an IRA to fund. In particular, if you intend to maintain this car for a long time. But as a buyer, I can definitely understand your temptation, John, to take a chance.
