Spark plug general advice
Discussion
Can anyone please tell me the sort of plug gap I should expect to find on my 2001 AJP V8?
Car has just started to run a little less smoothly than normal and upon examination started taking the plugs out to find much larger gaps than thought the norm. I know these coil packs kick out a fair old spark but.......
The plugs fitted were Champions. The ones I have to replace are NGK and I dont think it is normal practice to adjust these days or is it.

The gap on the NGK ones is smaller than the Champions fitted but also the 2 fingers seem lower to the insulation. Have aborted attempt to fit at present as the first couple I managed to fit (leaving the gap as they came) but the ones to the back of the engine where the exhaust manifold is a bit more of an issue were awkward with the socket I have. I need a thinner walled socket as it does pass happily into the plug hole but fouls on the cylinder head bolt.
I found that one of the plug insulations had come loose and had slid down over the electrode. (I've only done 2 out of the 8!) Not good for spark and only the 2 fingers keeping it from going into the combustion chamber. (It has a taper and is thicker further up the electrode)
Can anyone recommend a good thin walled socket for this job and are there any Cerbera specific problems with doing this apparently straight forward looking job?

Changed plugs plenty of times. I use a quality thin walled socket, plus a couple of universal joints and long, thin extension bars.
I always lightly grease the inside of the socket so it slides over the plug (fnar, fnar).
There is no need for anything to jam provided to take a little time and care.
I find a long magnetic extractor is useful because the plugs can fall out of the socket and back into the head.
Takes me about 60-mins to change the full set. Most difficult is driver' side bulkhead.
