Ceramic plug caps fit like a glove.
Discussion
Hi all, if you are needing new extenders I can recommend these as an alternative. I fitted them along with a set of bpr6es plugs around 2000 km,s ago and they have been faultless. I also fitted a set of heat proof socks as well but I now feel they were unnecessary as the ceramic part comes up past the header anyway. They do come un finished so you need to cut to length and crimp on the dist. Contacts. The angle on them is perfect to fit through the available gap which was a releif as I ordered them without this knowledge. So far showing no sign of problems will see how they are after a 1000 km trip planned this weekend. 
Nice 
I have well documented my deletion of the dreadful extenders using the excellent MSD Super Conductor leads combined with MSD Pro-Boot Guard over the plug ends followed by DEI Titanium Protect-A-Boot socks over the lot.
You can read about my six step process here:
http://www.pistonheads.com/gassing/topic.asp?t=143...
This system has now seen literally thousands of miles of testing and is totally proven to be 100% reliable with absolutely zero issues. And remember these are thousands of miles on LPG which is notoriously hard on ignition leads, so if my system is working flawlessly on gas you can be sure it's total overkill on your petrol powered TVR.
The truth is what you actually want for a perfect solution on our cars is a mix of straight and angled plug ends, knowing this I looked for a mixed end universal kit but couldn't find one I was 100% happy with at the time.
So I looked closely at both angled and straight end universal kits, as you can see from my post over a year ago I finally decided to choose straight ends. My solution for the leads that would benefit from being slightly angled was to gently cable tie them holding them at the correct angle safely away from the hot TVR manifolds, the other leads are definitely better off being straight by the way.
At the end of the day it's clear you can easily get away with either a straight or angled plug end kit, but a mixed kit would definitely be the perfect solution. As I like to carry a spare set of leads on my long continental trips I'll be making up a second angled end set to give me two perfect mixed end MSD Super Conductor sets.
To be frank I think the most important thing here is not if the ends are straight or angled, but that we are now proving without any doubt that it's perfectly possible to build a set a HT that allow you to completely delete the dreadful failure prone spark plug heat extenders TVR were forced to use to protect the standard Range Rover leads.
However you choose to do it deleting these nasty extenders is hugely desirable in my opinion, add a set of more suitable spark plugs and you'll definitely make two massive improvements to the rather marginal ignition side of these cars.
For a long time now I've been saying the NGK B7ECS plugs chosen by TVR are far from ideal on these cars, the B7ECS may well be be a good choice for a highly tuned Rove V8 Tuscan challenge race car...
But for a road going Chimaera... NO WAY
Fit a set of BPR6ES with their extended electrode and far more suitable No 6 heat range and you'll suffer a lot less plug fouling and will feel the difference, better still upgrade to a set NGK BPR6EIX iridium plugs and you'll enjoy additional benefits too (mostly longevity).
Here's my post way back in 2012 where I suggested people should start to consider ditching their original B7ECS plugs for the far more suitable BPR6ES or BPR6EIX alternatives...
http://www.pistonheads.com/gassing/topic.asp?h=1&a...
Of course at the time in typical PH fashion I took a lot of criticism for even suggesting the idea that TVR had got it wrong
, but I ignored the doubters because I'd already extensively tested the plugs I was suggesting and proved conclusively to myself they were an excellent upgrade.
So it's good to see three years on people are now finally starting to listen and are moving away in good numbers from B7ECS plugs and they are all finding the same benefits as I did all those years ago
The truth is I now actually run NGK LPG Laser Line plugs (No 2), which take the BPR6EIX iridium plugs to the next level by combining the the iridium tip with a chip of pure platinum set in the tip of the ground electrode.
These expensive NGK LPG Laser Lines will be overkill on your petrol TVR but on my gas powered Chimaera they literally double the spark plug service life so are well worth the money.
NGK make the very best spark plugs in the world bar none, FACT!
That's how NGK single handily killed almost all their competitors within a ten year period after entering the market, you have to respect the Japanese, the quality and reliability of their products are second to none!
NGK dominate because they are the best, they absolutely do not make false claims or sell snake oil products, so you can be 100% sure if NGK are telling you about the benefits of one of their new technology plugs it will do exactly what they say it will and in many cases will even exceed their claims.
http://ngkntk.co.uk/wp-content/uploads/2011/04/LPG...
But fit the wrong NGK plug in your Chimaera like TVR did and you are really asking a lot of even the very high quality NGK product.
However simply by selecting the right NGK plug as suggested above I promise you... "You will notice a big improvement"
Try it for yourself, then tell me I'm wrong
PS: If you find an online seller peddling NGK at a price that seems too good to be true, that's because it is!
Be very careful indeed because the market is absolutely flooded with NGK fakes, and a fake plug can do terrible damage to your engine.
Only buy your NGK plugs from a reputable NGK supplier that is known to sell genuine NGK products, or you may live to regret it
YOU HAVE BEEN WARNED!

Another thumbs up For these leads, ditched the DEI boot socks as not needed with these leadsHas anyone found a UK based supplier for "Accel 9002C Universal Extreme 9000 Ceramic Spark Plug Wire Set" ?
I've Googled but not found anything. I would rather not pay 50% again for carriage.
It seems from reading the various threads that the solution to the "extenders" is either these ceramic ended leads or the heat resistant "Design Engineering Protect A Boot" which I have found cheapest at Demon Tweeks, with the titanium set of 8 being £86.36 plus VAT.
The leads and extenders on my Chim are at least 9 years old and I want to replace as part of trying to stop shunting.
Cheers

I bought these instead as they have a higher heat rating:

Maybe overkill but have worked great in the 1000-1500 miles they have been on.

I burned through a set of the "normal" Protect-A-Boot sleeves in about a month on mine ... there are higher temperature ones available and you'll definitely need those (or better).I've Googled but not found anything. I would rather not pay 50% again for carriage.

Im guessing the 135 degree ones would suit the car as that is roughly the angle of the extenders?
Id be interested in getting a set of these too, they also sell the iridium plugs.
Be nice to get enough names to do a group buy, I don't mind receiving the items and posting them all out to everyone.
