A while ago, the original HT leads on my car started to give up the ghost, having succumbed to the heat, by the looks of things.
I replaced the lot with a bunch of silicon jobbies from Halfords, which are already on the way out. I knew it would be a temporary measure, but I didn't realise *how* temporary. I've had two go brittle inside the rubber boot that goes on the plug extender, so I'm sure the rest won't be far behind. (Thank god for spares in the boot
)
I haven't read anything totally conclusive about the merits of Magnecor leads, having heard good things, and so-so things about them in terms of their impact on general drivability. I'm more interested, though, to know what are considered to be good leads to get for longevity.

I bought some Magnecors a while back. Can't say I noticed any difference in performance but, for a while before they got filthy, they looked nice and they are still as flexible as they were when I installed them.
Not the cheapest mind, but then they were a Christmas pressie for the Chimaera...

I've used Magnecor for around six years on my SEAC and now run them on my BMW. I don't *necessarily* expect more performance (but it won't hurt) but they will last a lifetime and probably reduce the chance of electrical issues with the ignition system.
Expensive maybe - there are different types and some are cheaper - but I won't have to worry about replacing them ever again.

Except when they break down and need replacing... I am in two minds about them in practice. The 520 has them... the 500 is currently using bog standard Lucas ones which I can afford to replace three more times before getting anywhere near the cost of the magniwhatsits.
Both seem to be standing upto life about the same.

When the leads are new thay will all give the same peformnce. The spark plug makes determins the ark voltege.
The qualty of a lead will just give loger life.
A good set of spark plugs will take lower voltege than an old duff set.
So it is all down to how often you would like to replace you lead.

I have some Halfords leads on at the moment, which I put on about 3 years ago - they seem perfectly adequate up to now. However, they are really a pain to make sure they are all the way on. Some of the ends are starting to look a bit dodgy so ... I just ordered some Mangnecor leads, and a new dizzy cap since I don't think the cap has been replaced since the car was new (45,000 miles now).

Difference between types of leads like Magnecor and Halfords own brand is the construction.
Mags are stainless wire wrapped around a ferrite core to give the suppression qualities necessary.
Halfords are made using that old favourite.."carbon impregnated string".
Dont laff its true!
Intitially both types will perform well.
Carbon string types always change their internal resistance after a while, and its accelerated by heat, so instead of maintaining its correct resistance it increases it, not good.
Frequent replacement is necessary with these types.
Mags? Never had to mess with mine yet and have superior physical strength, most jap cars using Nippon Denso leads as oe.

I've never believed in the hype that's thrown about regarding ignition systems. A spark that jumps the gap at the right time is all that the Gods of Internal Combustion demand. But I did need a new set of wires for my Westfield/Rover V8 and Magnecor was running a special, so I bought some.
They actually did make a difference!!! The car now starts easier and runs smoother. Whodathunkit?

that's cool calseight!,
If the engine runs also better when it reaches the normal temperature,...then propably these spark cables are better.That means that the spark plugs work better and they burn the air/fuel mixture more efficiently, that's why it runs smoother.Do not forget that the huminity here in U.K. is too high at nights
so a more effective spark cable (different wire material) will work better in any circumstances.

philip_cooke said: So how much are a magical set of magnecors then? Are there local (ie UK) dealers or do you have to order then from the States??
Just ordered a set of leads (8mm) and a new set of plug extenders from www.actproducts.co.uk
Plan to fit them this weekend when I can get out in daylight!
