yep, they do. p/n 928 602 557 00 (or beru 0 300 513 124 / 1 kOhm). Same twist-on connection as the other leads.

The leads & connectors are available individually from Porsche, find the right length & good to go. If an odd length is required, find someone w/ a pair of Beru wire crimpers make a wire for you - Alex, i.e. IXLR8 offers to make wire looms on the side & might be able to help - see -> https://rennlist.com/forums/diy-subm...ion-leads.html. wire lengths are listed in this link as well.

See leads 13 & 14, or connectors # 16 for coils. 993 coil leads will be too short.


A couple of the shorter wires from my car are in usable shape if someone wants them to experiment, the lowers are cooked though.

Bumping an old thread.

I was looking for a writeup on two things.

First does anyone know where a good 964 ignition wire DIY is? I know I have seen one here somewhere.

Second...for anyone that has made the change to 993 coils...any benefit? I have only gone through three sets of coils in four years, but still that seems unacceptable for 30k miles. So if 993 coils are more reliable, maybe I'll make the change.

It's not tricky, just gotta get your hands dirty and expect the beatdown that is replacing 14 wires snaking throughout the top and bottom of the motor.

I've replace two sets, one on each of my motors. If you have the space/time/tools, dropping the engine to make the change, makes it a lot easier to do. It can be done in the car but snaking the wires over the fan shroud is not fun.

Rock on vandit, that's exactly what i was looking for. Any thoughts on running the cables behind the fan housing? Does the intake manifold need to come out?

Also, I am using a set of wires that require I reuse my clips, grommets and plug ends...so adding to the time, but saving money.

I did the job a few months ago as part of a larger project, and yea, having the whole intake off the car made it a cake walk. I don't know if I'd want to tear it all up just for wires tho.

And careful w/ reusing ends. I used the NGK set, so I had to undo wires to slip over grommets and what not, and I'd say about 50% of my old wires didn't unscrew when they came apart, instead the crimp on the end of the ignition wire gave and the threaded end of the ignition wire stayed in the end.

i had the magnecor wires and they did not last. fell apart from heat from the cat conv on the left side and some would fall out of the spark plug holes - i purchased the 6 pc rsr clips to hold the wires in on the spark plug side but did not use em because i replaced with the beru wires which are quite amazing looking. they plug up all the lower spark plug holes with lots of extra rubber and have little or no chance of slipping out.

so i'd recommend them over the wires with the cheap rubber covers that really don't keep all the water out esp when driving in the rain... that was also a hassle for me before. the car would stumble, stutter and stall when driving through puddles...

Got mine at rock auto for about $125 shipped

here is a 5% discount code for them good to Mid Jan 2016

Pics of install, I used 6mm threaded stock with spacer and nut to hold the ignitor pack in original vertical position, no modification to car required. A hole drilled in 993 coil bracket is all it needed (for threaded stock to go through) \

If (when?) my silver brazillians go south (again ) this is definitely the route I'll go; IMO it makes no sense to do it otherwise given the issues people have had with the silvers.

A bump for this thread.
I finished installing the 993 coils in my 170K mile C4. This was the last step after an recent (5K Kms) engine rebuild and a new fuel pump.
Difference is night and day compared to my unknown vintage coils.
Stabler idle, even before the (KTS 300) adaptation, and *much* crisper, stronger response to throttle inputs.
I don't think the car has ever pulled so hard since I have it.
