We have paid £90 + uk post if you want to buy some your self or set a group buy who ever wants them let me know and I will give you the contact details
He is a uk supplier
And I have NO financial gain

My original extenders are finally giving up so please let me know the contact details.

Thanks, Stuart

I'd be up for a set too, as not only the extenders are on their last legs, but the leads look a bit manky as well. Plus without the extenders they don't look like they are anywhere near long enough to use with just a set of heat resistant boots.

What's it like haveing a 5L and not 3L

Had her running again today, smooth as silk,rained all day,so taking her out for a blast tomorrow

Am of of for a blast tonight

I thought the same but they are just,boots are fairly cheap,try them

She ran excellant,a few more miles for letting settle down now all cylinders are up and active, and i think she will be buzzing

There a very Good wright up in the TVRCC Mag this Month about all of this...

[hillclimbmanic]

I bought the ceramic ended leads from the States months ago...As I'm doing a full restoration, I haven't run them yet, but it's reassuring to read all the positive comments...Phew.!!

[Ptr400J]

New to TVR and PH so forgive the questions but is there any reason why plug sleeves like sundely or insul boots can't be used along with silicone leads?

Seems to be stack of these sleeves on ebygum around £15 set.

6/7.5 inch long with 1200f (650 C ) continuous rating ,,,

The ceramic plug ends are just the most comprehensive way to resolve heat and connection issues at that end of the system.

I'm just running plug leads with socks no resistors but do use resistive plugs, I also run the Mbe Ecu which also seems to keep the engine at a lower temp generally speaking but I've found normal rubber plug caps and socks very effective as long as the leads are kept away from touching the maniflod.

I've used a few separators to try to keep the leads apart and so far it's been faultless.

The metal plug resistors can be responsible for odd running and misfire issues so it's a good idea to eliminate this problem area, saying that hundreds of these cars must be running ok with the resistors.

I've been using sleeves with not extenders for over a year now and they're working fine for me. The problem with them is that the quality serms to vary widely with no real way to know if you've bought a decent set until you've used them, price and brand doesn't seem to be an indicator. Guess that they're easy to copy so you don't know that you've got a poor quality set until a few months down the line when stuff has melted.

Either go direct to a high quality manufacture and feel like you're being ripped off, or take your chances with an ebay set. Think my set cost less than £20 and I needed new leads so I just trialed my sleeves with the old leads before I changed them to see if stuff melted.

To be honest if I'd known about the ceramic thingys when I was buying new leads and boots I would have probably given them a go, they're not much more expensive than a decent set of leads and cheapy boots and look pretty

^^^^ this

I'm also using just the socks with no sign of deterioration of the leads so far (after 2k miles).

Good value at £12/set delivered, www.banggood.com

Thanks for the replies, think I will get a set of sleeves as I already have Magnecor leads, new dizzy etc.

Can but give it a go :-)

Just need to choose a colour

This ^^^^^ and that ^^^^^

I get the feeling even the expensive ones would melt if they rest on the manifold for any length of time.
My problem with the metal resistors was they tend to spin and then touch the manifold, melted a lead that way a few years ago, so the rubber caps grip the plug better and keep the leads away from the manifolds far more effectively, the socks are then just offering some thermal protection which also appears to be effective. If any of these sleeves (socks) touch the manifold then they'll go brittle and fail pretty quick IMHO

ETA, ill wait until my socks or a lead fails but I'll be going for these ceramic plug caps when the time comes

Just bought a set that the description actually says ok to rest on manifold !, well we will see

On that note back to workshop to finish pulling the rad out

[davetripletvr]

Purchased a set of these boots to be fitted when i had my Turbo install done and they cost £50 so not cheap, and they failed on the rolling road when it was being mapped. They were not touching the manifolds but it was found that where the leads touched inside the boot it was arking and breaking down, so they were ditched.
These were purchased from Thermal Velocity and this is the write up from the website

Spark Plug Insulator
Spark Plugs Boots offer the same high temperature protection in an easy slip on sleeve that will extend the life of expensive spark plug wires by protecting them where they need it most at the boot.
Just slip these 3/4” diameter double thickness (triple thick at the sewn end) sleeves over any spark plug cable and boot (even right angle boots) to protect them from engine temperatures up to 650°C.
Once installed, the sleeves require no clearance from hot surfaces, and can even rest directly on hot exhaust headers without affecting performance.
Spark Plug Boot Sleeves are completely non-conductive, resist all engine chemicals, will not support combustion, and provide an easy, economical solution to the challenge of wire protection in the cramped, high temperature environment of any high performance engine compartment.



I did get a full refund

Very interesting re arking, I'll check mine as I've had one plug fail, which seems odd as I've never had plugs fail, I might take the sleeve off that cap and see if that same plug works again!

Thanks for that info Dave, even without the turbo these socks are so close to the manifolds and the temps intense I'm not sure any of them can take the heat over time so the ceramic ones do look appealing and possibly a saving!
