You should have a manual with your vehicle that gives you suggestive maintenance intervals. You should be able to contact your local dealership as well where they can give you this information from the manufacturer for free.
Refer to your owner's manual or speak to a mechanic you trust

Hi Cris -
Spark plugs are not recommended until 90,000 miles on your vehicle. It doesn't hurt anything to change them sooner than that, however it is likely not necessary unless you are experiencing some rough running or a check engine light that relates to the ignition system.
Hope that helps!

Most vehicles built after 1990 have a spark plug replacement interval of 100,000 miles on average, but the only sure way to know is to check your owners manual for recommended service intervals. Should you not have one'any Chrysler/Dodge/Jeep dealer service department will be able to give you a definite answer. If you are experiencing a rough running engine or obvious misfire, immediate attention to the ignition system is indicated. Hope this helps'Super Girls Auto
