The reason we replaced it is due to a turbo/power steering fire at the last rally, the next rally is next weekend up at Mundaring. We took it for a drive on Saturday, and all seems well, so fingers crossed.
The kit came with a new plug which we crimped onto the loom, as all of the plugs in the area (o2,and gearbox) were burnt/melted in the fire.
Wavey.
