i have the nology wires. they work great. i've had them for about 3 years. however, next time, i'll probably rebuild the original set (which i still have) for $12.

If you have a set of the original wires I would spring for a stock set. This will give you "extras". However you can also order just the weather boots from kingsborne too. Best to call them. They are a smallish operation and will still talk to you. Well maybe not after everyone calls them!

Another problem is the wire ends will come off and stick in the connectors. They usually can be extracted with some needle nose pliers and a bit of work. Sometimes you have to buy the connector.

I have only had the car for a month or so. the spark plugs look pretty new but if I had to guess I would say the plug wires are the originals. the reason I need new wires is that when the car is running I can here a spark jump, sounds like a ticking noise. got to looking and the number 4 plug wire has a crack in it. so if i'm going to change one and since they are probably the originals I just as well change them all.

That is the full set.

You need about 11 feet of wire and 10 ends #0.901.300.003.

You will also need the crimping tool #w/ZAZ5. However there is a way to do this with a home made "tool".

what kind of home made tool?

There is a trick for seeing in what shape the wire insulation is in. Wait until it is dark out, take a spray bottle of water and mist the wires. If you see a light show you know it is time for new plug wires. Or you can ground yourself and run your hand over them.:D

I made a hardwood "tool" for the outter barrel. I was using the $3 crimpers for round TV lead cables to crimp the outsides. I found that the outer barrel would twist on the insulation and not drive the threaded parts. So I drilled a tight diameter hole (for the barrel) in a piece of hardwood (walnut) with a smaller counter hole to it from the side. The counter hole is for a large nail. The tip of the nail is driven through the side of the housing to "spike" the housing into the insulation. I usually do this in three places.

Crimping the end where the wire inserts is a pain as the tip bends with a two point crimp. I just drill a small hole through the end and solder the wire in. It's the barrel and insulation crimp(s) that drives the threads into the connectors.

are we suspect of not already being grounded.............?

Hey forever,
I been this route w/ the beru ends and rebuilding the wire set. It took me a few weeks to realize that maybe the twenty year old boots had had their day in the sun (or under the hood) and it was time to move on (or move closer to the garbage can) I still have the original set hangin on a hook in my garage and maybe some day I'll rebuild em using the 1985 original beru ends, but in the meantime the magnacores are just workin really fine for very little $$$ and effort.

Consider ignition wires kinda like a pacemaker for you heart. I wouldn't reuse a 20 year old connection, and as I said before you can call me a cheap bastard if it makes you feel good.

Don't know why you wouldn't re use the 20 year old BERU ends. The carbon in them is only 4 billion (or more) years old.

If the ends ohm out with in spec they are reuseable. Arcing is found from cracked wires to the engine block or even the injectors (where it travels back into the DME).

Even the owner of KingsBorne does not suggest MagnaCores on the 944.

Hugh - do the 8mm Kingsborne wires fit in the original wire holders/separators?

I really appreciate this thread. I misted my "good" looking OEM wires last night and saw arcing at 3 points around the fuel rail. I wonder if those fuel rail fires don't have something to do with many of us having a pilot light nearby! Will new wires ever arc if they are misted with water - ie, is the mist test accurate??

Great thread... I wish we stickied stuff like this.

I think the fuel rail fires are usually from the fuel dripping on the hot exhaust headers though if you had it vaporized pretty much any ignition source could set it off.

The mist test is accurate. You don't have the dielectric resistance in the insulation jacket. If you have new wires that don't have good insulation properties for the amount of energy running through them, you may arc them with water mist also. That is why Magnacore uses the same wire core in the 8.5mm and 10mm wires and the only difference is insulation jacket thickness. If you are running some crazy high voltage ignition, like in a race car, you may want to go with 10mm to prevent arcing.

Stock size is 8mm OD. Should fit the stock clips. I've seen "sleeves" on some wires. Extra insulation that slips over the wires. I would think that raw gas and arcing from a worn set of sparking bolt wires would cause an engine fire sooner than just a hot engine.

I decided to get a whole new set rather than just replacing the wires. I called Kingsborne and they wanted $170 for the full 8mm set, but I got the names of local dealers. One sold me the set for only $94.90 + tax/shipping and he took paypal as payment! It took less than 24 hours to get the wires and they are just gorgeous in blue. Thanks very much for the tip about Kingsborne. This dealer even included a Porsche-crested keychain made in England that isn't half bad! Howard
