If you've noticed your mileage has started to decrease, your cars running a little rough or you're feeling some hesitation your worn out spark plugs maybe the culprit. Generally we recommended you inspect your plugs every 10000 miles, if they're a little worse for the wear we recommend you change them in order to get the best possible mileage, idle and efficiency out of your vehicle.

Our Mazda 3 had 55,000 miles at the time of the change. Although our handbook says to change plugs at 100,000 we noticed at 45,000 miles we started to see deposits and fouling so we set our schedule to change the plugs within 10,000 miles.
