Spark Plug Leads Too Long?!!

[MBleM]

The spark plug leads on my mkIV fiesta are leaking. All the spares parts stores in my country do not stock parts for my car but one supplier have a set of leads that are quite identical except they are twice the length of the original. i was told that leads that are too long can cause hesitation because the current flow has to take a longer distance to travel. it was then suggested that cutting the leads to the correct length will solve the problem. my question is can the leads work just as is and if have to cut them will they be jus as effective without any downsides.

modern plug leads are virtually impossible to cut and repair.
If you can find a roll of old fashioned copper core high tension cable you may just get away with it, but finding this stuff now is difficult, and it is nowhere near as efficient as modern leads,

Lol No Way!!!! The problem is finding a site that will ship to the caribbean. and i have no known relative in the u.k. can the leads be use even though they're twice the length. thanks for ur response!

LOL! don't worry about the length of these leads,if you can route them around the engine bay to make them fit they will do fine. within reason,it does not matter what length your ht leads are just try to route them so they dont lie on anything hot or sharp. you can make your own leads up by using old style copper cored high tension lead (still used in many types of industrial lighting systems) pushed into your old fittings and plug caps! ps. it takes about a billionth of a second for the current to travel down a lead of about a metre long so don't worry about hesitation!

If you get really stuck, let me know, and I will set some up on e/bay for you.
you will find me on Chatterbank mostly.
