review when last changed(maintenance history). manufacturers usually recommend every 50,000 kil. your vehicle will give you hints performance wise. reduced torque, horse power, and fuel economy. she may get lazy to start also. recommend replacement with premium plugs(e-3 is what i use, but platnum tip or better will do). they last longer with better performance results.
