Spark Plug replacement in Minneapolis
How often do I need to change my spark plugs?
In the past, experts recommended changing spark plugs every 30,000 miles or so. With today’s extended-life spark plugs, the life expectancy can go as high as 100,000 miles. Checking and replacing the spark plugs is usually part of your vehicle’s routine service interval. Rarely do you need to make an appointment just for the spark plugs. Consult your Owner’s Manual for more details.
Do I need to replace my spark plug wires?
Usually, yes. You should replace the spark plug wires when you get new spark plugs. With standard spark plugs, that might be every 30,000-40,000 miles or so. If your vehicle uses extended-life spark plugs, you could go as long as 100,000 miles before changing the spark plug wires. It’s still a good idea to regularly inspect the wires for any frays, cracks, and even bites (yes, bites!), since some wires are made from a soy-based material that’s a favorite snack for rodents.
