recently when checking plugs. I broke my #3 plug wire clean in half. Not having the money to purchase the OEM style wires, I bought a $25 set of Accel wires that were cut for a small block chevy. I was worried the way different impedance would hurt something, but they are working very nice. And I have another set for next time since its a V8 kit. Woohoo!

The accel wires are not solid core, right? Did you cut off the Beru ends and use them on the accel wires?

I did not use the Beru connectors, as that is the part that snapped. The only modification I did was I tightened the crimp a little bit for the rotor side of the wires. Engine is running fine, a spark is a spark.

"a spark is a spark"

Very not true.

Won't say how your setup is working on your car, not enough information, but a spark is not a spark. Energy of the spark makes a big difference.

Ask Chris after he sat on the side of the road getting a spark, but car no running.

well, shouldnt it be a more energetic spark now? I have gone from +/- 3000 ohm resistance to spark to something sub 500ohm. (150ohm/ft)

I understand the reasoning for the 3kohm resistor is to make the resistance of the wire negligible, and therefore get more or less the same spark energy in each cylinder. In reality though, what will that help? If a more powerful spark does anything, it would increase the combustion rate.

So what your saying is a spark is a spark, but a more energetic spark is better.

True that a more energetic spark is better, my point was that a spark is not a spark.

And again, not sure what your getting so I'm not commenting on what you have. Could be better, but my gut reaction is not. Porsche didn't use the Beru connectors to screw us out of money.

I made plug wires from an Acell kit for my old 924, no problem at all.

i have accel 8mm on my car, no problems, and they're bigger wires too, the connections worked pefectly, i think we did modify them though. i think we put the ends from the original connectors into the new ones. i dont remember for sure, but no problems..and cheap..and two sets...does anybody know if there could be a problem? does anyone know the info to tell if there could be a problem...i havent had any problem in a year or so with them, but curious

You guys will likely need new coils sooner than if you used the correct resistance wires. You are running more current through the entire ignition system and I think the coil would take the worst of it.

I remember an auto parts guy who "did me a favor". He knew bosch equipment well and he sold me the "same rotor" for my Audi 5000 because he was out of the correct part. six months later I replaced the $280 transistor for the ignition system. The part he gave me had 500ohms resistance, the correct part was 3000ohms.

Ignition engineers do their work well and all of their reasons aren't apparent. Since 944 coils don't cost as much I don't suppose it is a big deal as long as you don't mind waiting by the side of the road with your hands in your pockets!

My only question is how long do those Chevy wires last? I replaced my original set in the 83 with Beru wires and sockets 10 years ago and they still have no cracks anywhere.

The 7 mm wires have the same 16 gauge stranded copper as the 8 mm and the 9 mm and even the 10 mm.

So the actual current carrying element is not "bigger". It's just the insulation. Still you can get some interesting colors. See www.kingsborne.com.

The BERU wire set used on the 944's puts it's carbon resistance in the spark plug connectors. Others put it in the wires. Mainly to stop the noise going to the radio AM dial. All wires will eventually crack and arc to the engine.

I've had BERU 944 plug ends break but never had the resistor fail. I prefer their fit at both ends over that of after market or other OEM wires.

I also replace just the wires and not the ends.

If you continue to use those be very careful when you change your plugs that any debris that has fallen into the plug holes does not fall into your cylinders. Clean them very well before removing the plugs.

Chris_924s

indeed true. Very frustrating to diagnose as well. (BTW Sid- it's hard to believe that was almost a year ago!) We are all looking for ways to save a little cash on parts- if it works for you power to you. FWIW- I prefer my replacements equivalent to OEM stuff or better.

the lack of the ring around the plug is of some concern, but I will just have to remember to blow out the hole with the air gun before I pull plugs. I supposed that if I were ever rolling in money, I would put OEM style back on, but $25 to get the car running again was just too good to pass up.
