Preferred option HT leads?

[phillpot]

I'd like to get shot of the plug extender thingies, are these... clicky... the way to go and if so is that a competative price?

Thanks

You will need to add these as you need some straight cap connectors


I also bought these to crimp the connectors

The ceramic plug caps are certainly a solution to the heat issue. If you're going to do this you should be aware that those ceramic caps are brittle and have a tendency to lock tightly onto the spark plugs making life very difficult when you need to pull them to swap the plugs. Someone here found a tool that can locate under the cap to help ease them off.

There was a mention here of applying contact lubricant but I doubt that would help as it's very hot there so lubricant could turn into cement over time

Probably the same as these.

They are about £80 in the states so make your own mind up on the value of them!
Id hate to crack one and have to buy another set.
Most people opt for some reasonable quality leads and heat protective socks.

These have been on mine since the turbo was fitted. No problems so far - 2.5 years.

The price of those!!! BUT I have them on mine and two years in, spot on.

I do like to check plug colour every now and then. Once these are on they ain't coming off easily and keep the socks off the manifolds and they do a fine job. I'm expecting the leads to last 10 years
I like the ceramic ones but the risk of breaking them seems daunting and in fact the ones above are so good I don't think they would be any better over time.
They do look very nice mind

Hi Al, they look ike leads and heat socks so assuming both are good quality, that seems like a reasonable price? I can't remember what I paid for the heat sock but I am thinking they were £8 or £9 each plus the dreaded.

Got my heat socks off of eBay £13 a set of 8 and perfect

Look at this on eBay:

Nice find, a lot cheaper than the ones I got from the USA. From the picture though mine are a bigger diameter tube though.

I like my set up of iridium plugs, socks, no extenders and ceramic coated manifolds. Can't rmember the brand of HT lead but Chimpongas has been using an 8mm set on his LPG Chimp for years without degridation.

If I stick to my January plans I'll be getting a set of 'his' leads.

Fitted these exact ceramic leads myself a month or two ago. Ordered mine from America, this price you have looks good value to me, once delivery and tax is taken into account from the US.

I must say they were a pain to make up the ends, but very long thin pliers pushed through the distributors cap boots and then pulling the wire through helped a lot, as did a little spray of pledge on the boots to help things slide. The boots take some punishment and you can easily open the pliers to get over the lead without damaging anything. I didn't need anything other than what cam in the pack, the right angled rubber boots were fine and matched what came off.

The same goes for putting them on the plug ends, they are tight, but once they click into place, give a nice bit of security.

Went back and forth to Le Mans in the hot weather we had without missing a beat. Before, I had the classic miss fire and whilst I changed other bits, I did it in stages and the leads worked best.

Just my two pence, but I would highly recommend and shall be buying more of them.

I ended up fitting these, didnt work out much cheaper than some of the ones shown by the time they were at my door, but very high quality leads and socks that should last a lifetime!

Thanks for all the replies and suggestions, given me a few to think about

[Harveybw1984]

I must admit, I haven't used any socks on mine, just the leads as is.....not sure if I'll come to regret it but they stand up to the heat fine so far, I believed the bumpf on the box!!

I've been running my LPG Chimaera on a set of MSD Super Conductors for over two years now, LPG is brutal on ignition components so it really sorts the men from the boys. Unlike the expensive KV85 Magnecor set I ran before, the MSD leads have so far proved themselves to be totally bombproof.

They've also been the go-to HT leads in the USA for years for good reason, in the States its well accepted MSD Super Conductors are quite simply the best performing leads you can get

Buy better buy once, it always works out cheaper in the end

Use Magnecor - well proven and work well

This forum reported some Magnecor heat failures inside socks. Have they improved in the last few months

I tried some cheap ebay blue leads but they failed after a few hundred miles, probably heat. I've been perfectly happy with genuine Lucas leads for the past couple of years

Even if they did, they offer a 10 year guarantee?!

The unfortunate truth is Magnecor KV85 leads can fail even when used with socks as my photographic evidence clearly shows...



Even more disappointing is Magnecor do not honor their 10 year guarantee, quite frankly it's not worth the paper it's written on.

In their defense I have used Magnecors running petrol only on the standard and rather weak single canister coil and distributor ignition system and they survived, but I know of many people who've had issues with these leads including one well respected TVR specialist that point blank refuses to use them having had a catalogue of micro misfire issues, a number of failures, and finally an identical guarantee refusal experience to me.

Knowing how punishing gas is on HT leads Magnecor actively market their product to LPG users, unfortunately it's been my experience and the experience of many others that they quite simply are not up to the job, and when they fail you are very unlikely to get any recompense because the Ozzy guy who holds the UK Magnecor franchise will simply tell you the leads where burnt on your manifolds.

Magnecor leads exist in the USA, indeed I believe they are an American company with their Head Office being in Mitchigan, Magnecor leads aren't popular over the pond however because there are far superior products on offer from the likes of the mighty MSD who are by far the longest established, most respected and the largest producers of performance ignition components in the world.

MSD Super Conductors are the go-to leads in the US, which is a market that absolutely dwarfs what happens on this little island of ours. The Yanks don't mess about, you see Super Conductors on everything from street rods to huge horsepower dragsters and everything in between, MSD Super Conductors have been around for years with privateers and professions alike choosing to use & return to them time and time again... year after year.

Compare this with a guy who won't honor his own guarantee and will try any excuse to renege on it, MSD Super Conductors are the better lead by far, hundreds of thousands of power hungry V8 driving Americans cant be wrong. My LPG TVR is just further evidence that proves a point that is clearly already common knowledge across the pond.

Just to add years ago had a Griff 5.0 in with jumping tacho owner fitted these Red magnacors fitted my spare set of Lucas leads from when I was still using the dizzy and problem solved turns out 2 of his leads showed signs of the boots splitting and one had very high resistance compared to the others, told him to back them when they see the boots on the returned leads they refused to even rectify the failed high resistance one, outcome was customer was hacked off and out of pocket those Lucas leads di the job for years after using the cars old/used extenders with that attitude I could never recommend them seen a 4.0 Chimaera since with the lower spec blue ones with jumpy tacho rectified by changing the king lead only in all fairness they were not new the product looks of a good quality but contradicts what I have seen but know others are happy.... but with after sales like that why bother and over priced IMO my choice are these not the best but I got them cheap and they have the bendy ends so you can dial in the angle of choice still as new and 5 years old now https://www.summitracing.com/int/search/product-li...
