How long do spark plugs last?

Most newer cars recommend replacing spark plugs every 100,000 miles. However older cars will vary widely in terms of recommended replacement, which is related to the type of spark plugs installed. Standard plugs may only get 15,000 miles, while platinum tipped plugs can easily reach 30,000. Beginning in the 2010’s we have seen the wide adoption of iridium plugs that work great right up to 100,000 miles.
