Ceramic cap HT leads, plug fitting

[bobfather]

If I have understood this correctly the current supply of ceramic cap leads are for spark plugs with smaller terminal pips. Assuming that this is correct, would smaller pips fit our standard plug post thread. I've always liked the idea of ceramic caps but I don't want the hassle of having them break while removing the caps

Genuine Lucas leads with double socks. My number 8 sock is looking bleached. I still have the coolant pipes so space is limited there. They are all pulled up tight and the number 8 lead looks perfect, no sign of heat stress but I can't help feeling that this could be my occasional missfire

My two penneth, I've never lubricated a plug thread in 42 years of servicing cars for myself and my extended family. That said I did have a problem with the lower three plugs in my Smart Roadster. Two plugs per cylinder. Top plugs are easily accessible, bottom plugs require removal of rear windows, rear wings and rear panel so people (even garages) claim to have changed them but I suspect they often don't. I had a hell of a job encouraging those to come out.

I think time may be the issue, as long as you're removing the plugs regularly then they won't be difficult. Perhaps iridium plugs left in for many years could be an issue

Wow, how long, how many miles was that in there!

The longest I leave a plug in place is 2yrs, less if the milage hits 24k. Plugs always look brand new and shiny when I pull them.

Just need to claim OP status please

My original question was about ceramic caps but in reality I would be interested in any reasonably heat resistant angled cap leads. I did think about buying angled caps and fitting them to a standard set of Lucas leads but having investigated this they are mostly 'screw-on' type caps and I'm uncomfortable with that method of termination. Also these NGK and similar replacement caps appear to have springs, etc. inside leading to multiple opportunities for continuity failure.

Are there any angle cap lead sets of reasonable quality out there?
