should i change spark plugs?
I have a base 986 which i hardly ever use. Im not sure i cover 1000 miles a year in it. Regarding servicing i make it a point to still change the oil and filter every year. This morning i realised that its been close to 4 years since i last changed the spark plugs. That means that maybe theyve got just over 3000 miles on them. Should i still change them? I use denso iridium.
Thanks in advance
