MG Midget and Sprite Technical - Plug leads

Which is best type of plug lead?

I've got copper cored ones and made them up myself. Caused no end of problems as the suppressor cap 'screw' works loose..but what the heck, they are yellow and black and look great so I'll be sticking with them and doing a bit more road side fettling!!!

I've always used silicone coated with graphite cores..
Cheap, and seem to work well..

(less useful answer to the question would be, ones that work)

I tried a set of Magnacors once, only to have one of the plug leads start arcing against a dizzy cap clip. So it was back to the old ones. Arghh...

I found copper core leads made my rev counter flick a lot, so went back to the ones that fail every year.

I use silicon leads of French origin (Bought at Super-U at Le Mans, listed for BMC Mini on the label) in 2005

angled to come out of the Metro dizzy cap but the kit king lead was too thick in he insulator to get it on, so I used the older indeterminate king lead that was on it then.

Still works even without an insulator boot, about 3/8" from the steering column

I don't know why it still works...


note the fourth broken alternator adjustment bracket

:(

been using bumble bee (yellow with black stripe) for years and years, in a screw-tip distributor cap.

Never had a lick of trouble.

I used NGK leads on the racer, but they are NLA, I believe.

Someone was selling some new ones on evilbay recently, but they had no king leads for some reason.

Home made ones on everything. I bought the tools from vehiclewiringprodusts and have made my own for every vehicle including the aeroplane. You can make them up in seconds and reuse all the connectors. I've used carbon leads and non-resistive plugs on the aero and everything else gets copper cores and resistive plugs to ensure the necessary 5000 ohms.

NGK have a very good tech site that tells you about the most common plug/lead faults.

Les. When I restored my car, I used th 40 year old copper leads that came with the car when I bought it in 1967 and I've not had any problems with them so far. I don't have a radio in the car so I also use the old un-suppressed caps. They probably play havoc with my neighbour's tvs when I come down the street.

Agree with Bernie. I've collected quite a few old caps with leads over the years, and I've hardly dipped into the stock at all yet.

I use the original copper core wires, the ones that came with the car. At one point, I tried Lucas silicone insulated wires and had problems with the caps coming loose. Went back to the originals which now have about 250,000 miles on them.
