Well that'll learn ya! You should have bought an M3.

Stealth 993

Had a M3 for 11 years, it took me about 5min to change the plug wires in that car. The valve cover gasket was about 15min.

I love a good DIY, but for me, after buying all of the tools and parts, and spending the hours putting it all together, the Beru wire sets would seem like a bargain!

I'm a big time do it yourselfer and a cheapskate to boot! But, the $400 and change I spend on the Beru set was worth every penny in my mind. When you see the set with all of the grommets, boots, and clamps already in place and each wire marked with the correct cylinder/rotor location, it really makes the price seem more reasonable.

I did it with the engine sitting on my garage floor and the job still took about an hour! The wire placement and orientation to ensure everything fits the cap properly and making sure you don't misroute the upper vs. lower wires takes a lot of time. Can't imagine the PITA it would be to switch out all of the clamps and grommets from the old set to the new, then mark them to ensure proper location when done.

But, if you've got the time and are detail oriented, there is no doubt you can save some $$$ by making them yourself.

Well $200 vs $500 (give or take) is a big difference.

I'm going to put out feelers locally for splitting the price of the tool. Cripes, whats $325 if you've put a grand into torque wrenches. As I've always said, tools don't cost you money, they make/save you money.

And I can always put some cables together and sell them. I'm retiring soon.

I'll think about it.

More power to ya, brother. Let us know how they come out.

I bought the individual wires, and assembled the loom myself. Took less than an hour, so no big deal. Trick is to not disassemble the old loom until you have the new leads ready to pop in. Compare length of old/new lead, mark spot of where it goes through a clamp, place new lead in proper spot, move on.

Also helps if you have a dirty engine, so the clamp points on the old leads are well marked!

I think I pd. $130 for the wires with crimped ends installed from Porschesolutions. About 3 hrs and some skinned knuckles, but well worth the savings for me.

Alex,

I like the way you think! I too need a new set of wires (coming up on my 60k service)... I'd be very interested in splitting the tool with you. And, a spool of wire. PM me with you ideas... Maybe we could pass the tool around the Rennlist.

I'm kind of a collector of tools... No substitute for the right tool for the job, I always say! I often find that tools purchased do come in handy for future repairs... Besides, I don't plan of selling my 993, so this won't be the only set of wires I have to put on her.

Where are the tool and wires available from?

There must be some Scottish in me somewhere.

Having just changed my spark plugs recently, I took the time to jot down the Porsche and Beru part numbers molded into the spark plug caps.

Sure enough, the Porsche part numbers match those in the parts catalog.

Spark Plug Caps: Porsche PN, Beru PN

Upper 1-2-3: 911 602 314 00, Beru 0 300 322 109, 3KΩ.
Upper 4-5-6: 911 602 313 00, Beru 0 300 322 108, 3KΩ.
Lower 1-2-3: 993 602 313 00, Beru 0 300 322 116, 3KΩ.
Lower 4-5-6: 993 602 313 00, Beru 0 300 322 116, 3KΩ.

Good info!

I hate to keep nagging, but how about the resistors?
They are a wear item... when the wires are toast, there is likely more than one resistor failing.
They are not cheap and should not be neglected when taking on this little project.

Can anybody show a pic of what you call resistor, please???
I am making my own set too...

IXLR8

The resistor is part of the spark plug cap; it is built-in.

I haven't actually measured mine, but you should see a 3000 ohm reading between one side and the other of the spark plug cap.

Here is a NGK Resistor Covers page for information purposes.

Mark raises an excellent point.

Resistor failure of these Beru plug connectors has been an issue for 30+ years and these should be checked at LEAST annually for continuity and value. Its been one of the major causes for misfires and uneven running and these should be replaced at the same time the wires are done otherwise its a 50% job.

At $49/each for upper side connectors and $23/each for lower ones, to me its less expensive to buy a complete set of wires and connectors thats all ready for installation.

JMHO, of course,......
