Default Useful info on plugs...

Hi All,

Our Fiesta too has had rusted plugs, they all do it, without fail, just search the net. I mentioned to Ford service on very rare visit ( we had an EAC fault which had to go to the dealer), "really?, the first i have heard of it" he says in a I dont believe you kinda tone.

The other thing that happens when they are worn is some tracking of the spark. I had read a post from a person who had watched it happen while his engine had a slight misfire (with rusted plugs). Our engine too had the same thing on inspection.

Anyway, no point spending big $ on Denso etc, as they will rust too long before they reach their lifespan.

You can purchase Bosch Platinum Plus for the Fiesta, at around $23 a set. They have a 50k lifespan, but with any plug you put in, will need to be changed at about 25k tops due to rust.
