Hi how often do you need to change spark plugs? i las had them done at 135,000km at a dealership, the cars now due for it 150,000km service and im going to do the service myself and wondered should i change the spark plugs??
thnaks for your time
In an Ecotec, about every 30,000km should be plenty (if you have platinum plugs its more like 100,000kms+). If they were done that recently, don't worry about it unless they are causing you problems.
