I am also in the market for new leads, the only thing wrong with thses from what i can see is the lack of a dog leg bend at the spark plug end? P.S what about These? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&am...Edited by bhpjon on Monday 8th October 10:01
The leads from "Castle Race Engines" come highly recommended on here, I have purchased a set with the extenders which are a fraction of the cost of the premium brands and of just as good if not better. I think in this case most expensive may not always be the best quality.
If you do a search on here you will find the contact details for Jamie at Castle Race Engines. "CRE".

Which always hacks me off. As a (non-trade) member of the public there is no way to avoid VAT so I want to see the price I pay on the screen, not have to do calculations in my head.

Your computer is a very advanced calculator Which always hacks me off. As a (non-trade) member of the public there is no way to avoid VAT so I want to see the price I pay on the screen, not have to do calculations in my head.
or does Mr Gates charge extra for a calculator app these days? Constructive comments on web-sites are welcomed, but bashing these guys who are good at enhancing the TVR community rather than spending fortunes on glossy marketing blurb and web sites is out of order IMHO.Personally I prefer sites that load fast and give me just the info I want

I spent most of this afternoon with a firm which actually makes HT wire for some of the motor industry worldwide for OE fitment and aftermarket. Some of the comments were enlightening. It was great to find out about the three ways to make leads that are commonplace and how each meets the worldwide standards ref suppression/resistance and how even the best leads on the market have a finite life in a motoring application (heat, vibration, abuse by mechanics etc etc lol).
Also silicone isn't the best material to make HT leads from (in fact there's typically a max of 22% silicone in most HT leads advertised as being silicone leads, as you would expect the raw fluid silicone is mixed with other stuff to make it useful for HT lead applications) .. but silicone is very good at withstanding high engine bay temps so it's use is widespread, but there are better alternatives if heat isn't a major issue. one of the main problems with silicone mix leads is that they're very elastic which can break the internal conductor through vibration and mishandling.
The most astonishing thing was that the machines in their works can make something like 6 kilometers of wire .. an hour!
The bottom line appears to be : not all leads are the same, there's a lot of marketting hype in advertising HT leads and price definately doesn't dictate quality, although there are some good high quality leads out there

Anyway, i can recommend Castle racing engines own brand,look nice too(blue)and stuff paying Magnecor prices for HT leadsAlso silicone isn't the best material to make HT leads from (in fact there's typically a max of 22% silicone in most HT leads advertised as being silicone leads, as you would expect the raw fluid silicone is mixed with other stuff to make it useful for HT lead applications) .. but silicone is very good at withstanding high engine bay temps so it's use is widespread, but there are better alternatives if heat isn't a major issue. one of the main problems with silicone mix leads is that they're very elastic which can break the internal conductor through vibration and mishandling.

I got a set of Bosch leads for my V8S and the difference is unbelievable - smoother, much better pickup at low revs, just way way better all round. They do feel very nice quality too. Got them as NOS on ebay for £15 (listed for a V8 Land Rover) so I'm assumimg they are still available new.

Can't find these squire, any chance of a link please?Chris.
I bought some cheap leads off eBay similar to these in the early part of summer. Two trips later the damn things started to breakdown causing an exciting time returning through show traffic. Bought a set of Magnacor's and for the last few months perfect running. I also strongly recommend only fitting Lucas ignition cap and rotor. All these parts do cost more than cheap alternatives but the others break down with the extreme heat under the bonnet. (I know from experience)
If it’s any help, I get my consumables off eBay through 'PartsRange'. The guys there are very helpful.

hi ,i wnt for magicor cost a fortune and there rubish , think your better off with standard bosche
Mine were rubbish to i've also gone back to standard leads. They started to crack where they connect to the spark pulg and at night you could see them arcing across to the manifolds they were also only on the car for a year.
Total waste of money IMO

I should have sent them back but they went in the bin.

I know I have dug up an old thread but I need some new leads. TVR parts have quoted £29.95 for a set of standard lucas set or £72 for Magnecore. my question is; has anyone used lucas leads. and is it worth paying the extra for magnecore.
I hate to advertise for them but at Halfrauds you can get Bosch or Halfords own (Lucas?) for around £25 or so.I'd recommend the Bosch ones anythime. I replace every other year and at that price its affordable.
Trev
I have seen two Chims on Magnecores,and no would not recommend them(arc city,with jumping tacho)i used the CRE leads with their own extenders,two years later no problems my brother as them also,in saying this Bosch or Lucas leads will work just fine
i must confess the CRE ones are blue the same colour as my hoses(that helped sway it)
