What is so special about Magnacore leads, and why do i want to pay the extra.... which by the way i do not want to pay...UNLESS these is a good reason. I have no problem paying for quality, if it is worth it!
I fitted Magnecor to all the S2 6cyl, Real S Type, MK10, cars waaaaaay back, 25+ years at least.
Still there and fine, as I still maintain 3 of those cars.
The V12's ALL got Magnecor, $55 a set back then, AND, the ONLY supplier that supplied the 90deg for 1A & B, and 6B, and 5A, AT the plug end. Straights at those #s for plug end are doable, but 90deg, sooooo simple. Some of them are 20+ years old, and done mega kms, and lots of plug changes.
Th last set, Bosch, were 90deg at the cap, standard, and straights only at the plugs, but that car has a compact Sanden A/C compressor, so easy as. The othrs we made them fit.
The Magnecor supplier in those days was in the next suburb to me, and he actually knew what the HE needed, and number tagged each lead. Sadly, they be gone now. What they supply now, I dont know.
HAHAHAHA, welcome to the AFTERMARKET world that I have worked in for 55 years.
Their listings are worse than a politicians promise list, and I gave up years ago trying to get them to sort anything.
PreHE V12 are different, coz the plugs are at different angles,AND, Straight at the plug ends IS needed, no exceptions. Also the lengths are "slightly" different on some due to those plug angles.
NGK, AC Delco etc, as Doug has mentioned, are all excellent leads.
Plug leads have come a looong way in the last 8 or so years.
It will get messier in a few years as the COP market takes over, and plug leads become a supply and demand item, and then stocks and prices will get scary. Some markets more so than others.
Has anyone looked at colored ignition leads? I was thinking of getting some red ones to add a splash of color to the engine bay. I don't know, maybe I've been watching too many episodes of "Pimp My Ride..."
There is a vendor on eBay called "Mr Retro Leads" who claims to make the leads at a workshop in the UK. He claims they are wound wire leads with Kevlar core with a nominal resistance of 5.6kOhm.
At a price of 55 GBP, it won't kill me if I end up having to throw them away, but thought I would ask this group for any comments on functionality and aesthetics.
Finally got around to installing new HT leads. I chose red to add a dash of color to the engine bay.
I ended up getting 8.5 mm leads as I was concerned that the 10 mm version would be harder to fit.
Saw an an immediate improvement in engine performance over the old leads — due to the fact that I had inadvertently pulled one of the old leads loose when reinstalling the injectors and fuel rail!
Could have done a tidier job routing the leads if I had done this when the fuel rail was out the first time.
The red looks pretty good. I was not too sure when you first mentioned it. On the general subject of ignition leads, yes, pre HE and HE take different leads, so get what is correct for your engine. Beyond that, almost any leads work the first time around. The real difference comes in later. Cheap wires tend to pull apart easily when you try to disconnect them many miles later. You have to disconnect them very carefully. They are also less resistant to chafe, and will wear and short out easier than more expensive leads. That said, I have had very good luck with cheap leads.
I have some Denso 8mm that I haven't put on yet, sitting next to the dozen NGK spark plugs I bought. I put in my year, make, and model, and these are what Summit Racing's search engine spit out. I have to get the Benz back together before I put the Jag back in the garage, so we might find out how they do next weekend. Or the weekend after that...
