Well, I wouldn't call the Bosch wires total crap but they are certainly not appropriate for our car. Our car has simple standards--resistor ends, solid wire. Most of these sets have conductive silicone or carbon, and often resistor wire, too.
Beru wire, Beru ends, Bosch ends, Bosch wire--as long as the resistance is correct, and the wire is solid, you are OK.
There are plenty of places that either have them or make the sets. Check with Dan Caron; check with sltech; I had a set made in California with all original Beru parts by some place I'd never heard of and whose name is lost to memory.
What typically happens is people are aghast at the price. The Beru ends at the spark plug typically cost about $20 each. So, you are at $180 just for those ends. Add the wire, and the distributor cap ends and you are well over $200 and it's no wonder why people go to Autozone and buy a "ready made" Bosch set for $45
