any recommendations for leads? Mallory? MSD?? not had a very good experience with magnecor but open to sugestions,
A company called formula power use to sponsor the forum, did anyone try their plug leads?

Hi, I do not know if this helps but when I needed new leads for my v8 spitfire I ended up making my own using the performance HT leads from this company https://www.autoelectricsupplies.co.uk/ . I have had them on the car for about 3 years and have had no problems so far, the only real cost is having to buy the proper terminal crimping tool.

I'm using cheap ass leads I bought off ebay that had the spark plug ends I wanted. Then just cut the coil end and crimped a new bit on.

People can get over worked up about leads....as long as they dont leak and the ignition system is good...really nothing fancy is needed.

Think they were intended for a Ford Explorer or something

Actually bought a couple of sets ( as they were intended for a 6cyl, and I needed 8 lol )

Not sure how they'd suit a Rover, but probably wouldnt be too bad

Since I have EDIS on an RV8, I made my own to get the correct lengths. Being a cheapskate, bought used EDIS leads for the connectors and new cable. I have quite a selection of crimp tools and looked to see if I had one which would do, and ended up using a BNC (video/data coax) one, which produces a hexagonal crimp. These are a common tool, so cheaper than custom made ones. leads have been fine for several years.

Exactly what I did (apart from buying new EDIS connectors)

I've had all mine custom made up by Fastlane Automotive, who are now know as FLA manufacturing.

http://www.fla-manufacturing.com/products/index

They still make leads for individuals, just tell them what lengths you want, the edis cap type, what plug end you want and any special things like heat sleeving or numbering.

They use decent spiral cored cable without paying the stupid magnecor / mallory tax. You have to remember that EDIS packs deliver a decent fat spark and dont really need high end leads.

Be interested to know the benefits of spiral core - did any car maker ever use it? Conductive plastic is what I used - a far better resistive material than carbon impregnated cord. And most ignition system are designed to use with resistive leads.

And absolutely no mention of conductive plastic leads - which Bosch have made for many a year. Bit like the Duracell ads where they compare to carbon batteries. :D

Some of the claims relate to interference and helping on cars with multiple spar ignition setups.

Really..with todays even half modern coils, almost any half decent lead will do. Most important thing is they dont leak. There are other places to spend money than buying really expensive leads. Although there can certainly be no harm from buying them if that's what you want, but dont expect them to suddenly release loads of power or anything
