Also know, how much does it cost to change spark plugs on a BMW?
The average cost for a BMW 328i spark plug replacement is between $144 and $300. Labor costs are estimated between $120 and $152 while parts are priced between $24 and $148.
how long should spark plugs last? Most spark plugs have a factory service interval of 100,000 miles, though some may be as much as 120,000 miles. Long-life platinum and iridium spark plugs will typically last up to 100,000 miles or longer provided the engine isn't using oil or doesn't spend a lot of time idling.
In this way, how often should you change spark plugs?
If you check your owner's manual, you'll probably find that your automaker recommends you replace your spark plugs roughly every 30,000 miles. That's fine if you're using stock spark plugs. However, the actual timing of replacement will vary depending on other factors.
