I think I just made a big mistake. Tell me it ain't so. I went to replace my spark plug wires and ordered a new set of BERU. The vendor shipped wires for a Euro by mistake. When I called he olny had Nology in stock and a replacement set of Beru would take another week so i told him to send the Nology. When I installed them I did not use the spacers from my old Beru set and the Nology spacer set hardly fit. I ran the wires in bundles held together with tie wraps. I was thinking that the new technology wires did not need all that space. The car does not run very well at all and I am thinking the way I ran the wires is the reason.

Do you mean the wire spacers that keep the wires neatly placed? I don't think they'd make a difference. It's more likely that you've got some bad connections or a resistance/capacitance mismatch. Could you have connected the wrong spark plug to the wrong connector on the distributor?

The spacers should not make a difference. New wires should not need any spacing. Try to return them for Beru wires.

Similar Beru wires on a BMW 3.5l six are collected into a 3/4" pipe running along the engine - they couldn't get any closer ....no signs ever of 'cross talk'.

double/triple check that the wires are running to the right plugs.

While the jackets are intact there won't be crosstalk. The purpose of the spaces and such is to hold the wires away from metal parts that will chafe and ground the wire.

I spend extra time working with the spacers so it looks neat and orderly.

check your plug gap. .032 is max for a 928, anything between .028 an .032 should be sufficient.

Thanks, now to look elsewhere.

I'm not sure about Nology, but the Beru style wires I installed were a little stiff going onto the plug. I used a socket and an extension to push down on the top of the plug until it audibly snaps onto the plug. This may be something you want to check. I can see where it would be very easy to leave one loose.

The stock system in my opinion is the superior one, the reason is that the wire is not the resistor, the spark plug end is, this way the same current can be delivered to all plugs, the wire in the lead of the Berus is copper a great conductor, despite all the fancy spec of other aftermarket leads, they don't conduct electricity as well as copper.

Hope this helps.

I posted what I found about the Nology wires in 2003/2004.

Let me say it again: I use a SUN Oscilloscope on my ignition system, and can literally see the spark voltage at each spark plug as we tune the motor. After paying more than $350 for Nology wires, I was surprised to see that there was not more spark at the plug AT ALL. No difference to the Beru wires I removed.

I ran them anyway - until I started having spark trouble mid-season in 2004. Spark plugs were dropping spark.... I replaced the distributor cap and rotor trackside - no help. Found a bad ignition wire and replaced it with a spare from a friends car jury-rigged to get me to the end of the day.

Within a month, a total of 3 Nology wires had failed. I was so pissed, I ripped them off the motor and threw them in the trash. Its hard to throw a $350 set of ignition wires in the trash, but you get that mad.

But - then I wen back and pulled them out of the trashcan to cut them up and see what was in them. Wanted tosee the super-special capacitor thingee that Nology was always talking about.

Nothing. Its an ordinary damn wire with a braided ground strap arounds them and a slick looking cover. No capacitor. I reported my findings to Nology and the shop I bought them from. They said the "capacitor" was between the layers of the the silicone to the ground strap. Bull****. Sorry, I have no other word for it.
As the silicone is a very good insulator (that's why it is used on high voltage wires) you'll not get anything stored across it or returned back over it to aid in the spark. There IS no capacitor.

Save your money. There are a number of nice 8mm Beru wires available from The Big 3 including us, and they all do a nice job at a far more reasonable price. We have them in several different colors too.
