I have just changed my plug leads after 38,500 miles and what a difference, smoother, more responsive and feels like more power and torque too. Job was easy to do and cheap, £53. I would say to anyone with a speed six, do not leave it until that mileage before you change your leads, i would say 20 to 25k and no more.
The hardest bit was re-sealing the spark plug cover back neatly.

Why?
As an engineer do you feel the leads are subjected to more load? then usual cars. Cheaper by design?
I would be interested in what other people have to say about this point raised. I just cant see why you have had such a tramatic change over so few miles.
(Ah, Edit how many years has it taken to reach the 38k)

Fernhurst change the leads every service i.e 6k miles, the leads are subject to greater heat than on "normal" cars, the leads break down with the heat very quickly, changing the leads regularly on a Speed 6 is common practice.
Intertesting! Thanks for that, There is a wheel posting with your name on it. Have a look

Yep thanks for that Paul I told Woody 2 weeks ago i had sold my old silver spyders... bless him
First off, it has taken me 5 years 3 months to get to 38,000 mls.
I also argee with the heat issue on the leads, and now having seen the route they take there could be an issue with rubbing, which could cause the insulation properties to brake down too.
I had heard that Speed sixes should have there leads changed at the 18k mark, but as it seemed to run ok so they got left, but as they brake down gradually you will not realise how bad they are untill you change them or go on a rolling road.
For the little cost and ease of changing them it is worth while and they could pay for themselves due to loss of efficiency.

Fair point Kev !
EDIT: I am still learning why these machines do not act like normal cars! most cars run at 92 with no problems of copper breakdown issues. And you would think with it being a SP6 it would not have the usual engine swing/movement issues either!
Must be out puts through the leads are excessive as well as the tight route path as suggested!
Interesting!
