Ceramic plug caps fit like a glove.

Very interesting re arking, I'll check mine as I've had one plug fail, which seems odd as I've never had plugs fail, I might take the sleeve off that cap and see if that same plug works again!
Thanks for that info Dave, even without the turbo these socks are so close to the manifolds and the temps intense I'm not sure any of them can take the heat over time so the ceramic ones do look appealing and possibly a saving!
Agree, will go ceramic when time comes as all new leads and plugs at presentThanks for that info Dave, even without the turbo these socks are so close to the manifolds and the temps intense I'm not sure any of them can take the heat over time so the ceramic ones do look appealing and possibly a saving!

Is there a UK supplier of these leads?

...just dont hit 'buy' til you see the postage.

Ceramic being a brittle material I'm concerned about the amount of force some people require to apply to disconnect from the plugs. I have seen earlier comments on connector lubrication here but in a hot environment lubrication will volatilise and therefore have a limited life. The lubrication could eventually become a cement which could exacerbate the stiction issue. Is there any follow-up on the long term effectiveness of the lubrication? Perhaps annual clean and reapply would help.
I was thinking about making a tool that could slip under the ceramic cap so that the removal force would be compressive to avoid any tensile and possible bending forces for which ceramics are weak

well said Bob, after using these for a year or so and around 12000km,s i have indeed had trouble removing them and i originally thought it was the rubber sleeve sticking to the plug even though i used dielectric grease on them? until recently when i had trouble removing one of them even with a hook tool under the ceramic so as not to break it {as you so clearly pointed out} i got it off but the metal end piece remained attached to the plug. so it appears that the problem is the metal clip on the end which is far too tight on the plug. this i remedied by using a dremel tool to grind down the little "pips" inside the metal piece until it was a nice click on fit on the plug so i would recommend doing this to the leads before fitting as they are a ridiculously tight tight fit out of the box.I was thinking about making a tool that could slip under the ceramic cap so that the removal force would be compressive to avoid any tensile and possible bending forces for which ceramics are weak
other wise they are fairing well and it was easy enough to slide the ceramic piece up the lead to re-trim and re-attach the end.

My initial thoughts were that the leads could be disconnected from the distributor and then unscrewed off the plugs leaving the sparkplug pip inside the ceramic cap for removal off the job but I doubt the angled caps could complete a revolution without hitting the exhaust headers other wise they are fairing well and it was easy enough to slide the ceramic piece up the lead to re-trim and re-attach the end.
