Spark Plug Extenders

[locodude]

Can anyone tell me if the spark plug extenders fitted to thr Chim/Griff are supposed to spin round on the plug. Mine all do and sometimes the leads short out causing a misfire, especially on the driver's side on the coolant pipes. I would have thought they were meant to be tight? Can the clamp be 'nipped up'inside the extender or is it made of 'monkey metal'. Thanks in advance.

My old ones turned and the new ones too, never had a misfire either. I would think that as long as it takes a little bit of force to pull them off then they should be OK.

They'll move around if pushed, but they shouldn't be 'floppy'. Sounds like the rubber grommet inside the extenders may be perished?
One of my pre-drive under bonnet checks is to push all the extenders on tight and make sure they're seperated from each other.

Also if they spin they arc between the manifolds causing a misfire and breakdown of the leads.

A full set is quite cheap from

Cheers guys, it looks like the rubber inside has perished or seen better days. I'll order some tomorrow, may even treat her to some new leads. Any recommendations (Magnecors seem a bit dear!).

no they should not come off easily, when fitted right you can feel them clip on, mine were getting old, and I thought could effect emmisions,so replaced with new ones, bought them off chap on ebay, came next day, nice shiny and new (RPi TVR Rover V8 Ignition lead Morgan MG Plug Extenders) hope that helps,Cheers C/P

Magnecors are expensive and there was a problem with a batch a while ago. However I had persistent problems with my leads but since switching to magnecors it has been fine. My experience is that they are worth the investment
