I think my leads are past their best. I have the yellow silicone ones that came with the yellow 'Harley' coil that I've had on there for ages.

I had an odd misfire on start up recently and one wire end seemed a bit loose so I tightened it with pliers and that sorted it. I don't really see what else can be wrong with such leads but the car is still a bit more juddery than usual.

Do we have any preference for new leads that will fit this? Looking online I suspect my choice is pretty limited because of the ends needing to be at right angles where they attach to the coil. £45 at Ecas for some reason.

I believe the recommendation is the standard black coil in pair with Bougicord lead set.
Nevertheless if you keep the Harley coil you better get the silicone leads.

Thanks. I've quite liked the Harley coil, it's been on there quite a few years now. I did have trouble with the original ones overheating. Are they meant to have an advantage though?

Old leads get pourous and sparks can go to the earth. I had a loose connector too that caused the connector slowly being burned up by the sparks.
Bad adjusted contacts can cause overheating of the coil. I had that in my landrover. It worked well in freezing temperatures but as soon as it got warmer the coil got to hot. I had to adjust and maesure the contacts several time to get close to the handbook contact angle. After that no more overheating coil.

I can't help thinking I'd be wasting my time replacing the leads. They should be fine if they're silicone. I did tighten up the connections.

If it works it works. Are they clean inside ?

They look fine to me. I don't think the silicone ones get all leaky over time.

And all the electricity running out....

Haha. That would explain some things! Lol.
