When Should I Replace Spark Plugs?
im at 44k miles and i herd you should replace spark plugs around 30 - 60k miles and i was gonna do it at my next oil change which is at 50k so would it be a good idea to swap my spark plugs? i had to change the battery before the battery was from the factory so i was thinking the plugs are from factory also so i was just wondering if this will help with anything, and what type would you guys recommend? oh and i drive a lot for school 3 days a week 1 hour to and from school so 6 hours in 3 days. just trying to help mpg as much as possible.
