Ceramic plug leads - any long term issues?

I've never understood why anyone uses fancy plug leads - if you have decent coils then they should make zero difference to anything! I just use some boggo old land rover ones and they work fine!

Not so much the lead but the plug end and getting rid of the uter st extenders

Unfortunately Nick, since all your work afew years back and you being a resident of these forums,the quality of replacement items over the years has far deteriorated, to the point you cant rely on what anyone tells you....poor people working their arses off for little pay with crap materials.

Thanks for your very comprehensive and informative answers Tej, I assume because you haven't highlighted any risks associated with using BR6ES or BR6EIX in a Chimaera you consider them perfectly safe in a road going TVRs fitted with the Rover V8?

To summarise we should assume all the there options are safe (B7ECS, BR6ES or BR6EIX) in the Rove V8, so final selection should be dictated by personal driving style, state of engine tune and ultimately what proves to work best in each Chimaera.

Finally its important to stress TVR famously overestimated their power outputs, and even TVR owners themselves who'd love to claim the big power bragging rights accept TVRs claimed power figures were largely a work of fiction to help sales.

Thanks again Tej, your input and expertise in this matter has been very helpful.

I think you have answered your own question in your post

Anyone experimenting with plug heat ranges knows the risks involved and I can see that you understand this (I've read the thread you mentioned previously) subject well enough to know right from wrong. The fact you and others have been running the projected 6 heat range plug with no apparent ill effects would indicate you are satisfied with the plug you have selected. I don't think any input from me is going to sway anyone's opinion on this front

Although TVR overestimated the power outputs of their engines, I would think they are still in a higher state of tune than a 'regular' Rover V8 4.0 which I think produced about 190 bhp?

Anyway apologies for the thread hijack, I think those leads with the ceramic end caps are the bees knees

This choice of rather cold plug by TVR may be a carry over from the fact that back in the early 90's TVR were using this engine in competition in their own race series know as the Tuscan Challenge, these Tuscan race cars used the same Range Rover sourced Rover V8 but in a much higher state of tune than you will find in their road going Chimaeras, fitted to a race car the engine was also subjected to much harder use so I can see why a NGK B7ECS may have been chosen.

I,m just wondering why I have been using BKR5EKU in my race engine for the last how many years. Never had any plug issues in that time excellent plugs in my opinion.

Knowing how superior the heat range is on an NGK plug (instilled from my Honda days) over all the other crap competition (OK I do like Denso however) I am not surprised 77Racing

what I like about NGK is their external appearance also compared to the competition, study the quality of the ground and centre electrode against a Bosch or Champion ... I rest my case

lol

It must be the twin ground electrodes that actually turn the plug into a '7' heat range

They are made to a very high standard, that much is obvious to the onlooker

So well made that any plug will do then
