My cars recently started missing at high rpm's. Not all the time, and it's only over 5000 rpm.
It has been suggested that a damaged HT lead can cause this scenario.
So today I've been looking at HT leads, I am now confused (I know, that doesn't take much doing).
Is it worth shelling out for Magnecor leads, or are the standard Range Rover ones just as good?

I replaced mine with the Magnecor KV85 Competition 8.5mm silicon leads(i.e.the red ones!)from Tim at ACT.
I can't say that I noticed any performance improvement,but,they are a lot better quality than the standard landrover ones.
Even though they're more expensive,it's cost effective in the long run,as the standard leads soon become brittle and break down and these shouldn't do.

Reviewed the forum on Magnecor leads (£75/95+)and then visited Halfrauds - Rover leads (Halfrauds) at £30, Bosch leads on special at £24. No brainer.
Not sure what the "real" advantages are to a low-ish reving 4-stroke engine. Can't say whether "quality" comes into it - Bosch/Halfrauds are good quality in their own right
Completed 2-track days, never missed a beat, frankly, other than when bonnet is lifted and you "see" Magnecor leads, I don't see the "real" need for the extra cost.

The big issue is heat, TVR engine bay = oven
Although i'm obviously huuuugely biased
i could supply /stock original leads if i wished. Steves comments are spot on, if you're not worried about the condition of the leads in a couple of years time (maybe you are selling the car) fit standard.

Dont dismiss the shrouds either.. .. ..two of mine were shot when i checked, and with a set of magnecors from (I think) ACT, they were only an extra £2.00 each

Sorry, just got home and checked, i got them from Motorsport World in Strathaven, not ACT. My mistake.

I had a terrible crackling misfire above 5000rpm for the first 1½-2 yrs of ownership and everyone said it was just the soft rev-limiter kicking in at ~5k before the proper 'hard' rev-limiter at 6k-odd.
Recently I had the car in for a service and was told that my HT leads were perished and heat-damaged and should be replaced, so I gave the go-ahead.
When I picked the car up, after it was properly warmed up, I gave it some welly and promptly wound the tacho round to over 6k rpm and hit the rev-limiter (ie. the mythical 'soft-limiter' had gone).
Proof positive that HT leads can make a world of difference.
I have to say that the standard leads look really weedy - like bell wire (I'm exaggerating, obviously) so when finances allow I may consider the Magnecor ones.

As Tim said, heat is the enemy.
If you need to change the leads, the plug shrouds or extensions will probably need changing as well.
£7.95 each plus VAT if you stick with crappy Landrover leads or £2 plus VAT each if you fit Magnecors.A saving of £55.93 in my reckoning!
Changed my leads and plug caps at the service on advice from Austec, you could see them breaking down at high RPM when it was on the rolling road. I guess the ones that were on there were the origionals.. Wow what a difference pulls better and stronger up top than ever.. Have just ordered new rotor arm and cap + coil as well just to make sure ignition system is 100%..
