No clue on the Niehoffs, probably just OEM replacement stuff I'm guessing. You have to go to a speed/hot rod shop for the better ones usually.
I'm just not a fan of resistor wires anyway, they all wear out over time. It's just a cheap and dirty way to suppress EMI/RFI. Something like Magnecors or MSD Superconductors that's a helical wound conductor instead of a carbon impregnated "conductor" just makes more sense to me. The Accel 8.8 wires are also the carbon variety unless they've changed em recently, in which case I stand corrected.
The downside is that good wires aren't as inexpensive as the parts counter sets are.
Probably gonna be shelling out some money this week for a new set myself but I think I'll just order another 6 feet of bulk MSD super conductor and some new boots and terminals since I have the MSD crimper already anyway and some wire leftover from the last set I did.
They're a little more time consuming since you have to assemble them yourself and you can get universal import kits for around 60 bucks or so, but here's a secret. Just buy one of the 8 cylinder MSD wire kits. Make sure you get the straight/multi-angle type plug terminals and either straight or 90 degree socket style distributor terminals. They have some that are the GM HEI distributor type terminals which won't work on our vehicles. Anyway, the dirty little secret is that for about the same price as the generic 4 cylinder import set that MSD sells, you get enough wires to make 2 sets so you either have spares or if you have another car that doesn't need the funky type terminals like some DOHC cars can you now have a set for that as well.
Magnecors are about the same price as the MSD's or a little bit more, but they only sell custom tailored sets as far as I know.
Either of those are pretty good wires, just stay away from stuff like Nology or any other of the "capacative" type wires, that's purely marketeering and doesn't do anything except lighten your wallet. I'm not sure about the quality of the Jacobs stuff either, opinions on the Jacobs products in general are either really good or really bad. Given the pricetag though I think I'll just stick with the MSD's or Magnecors.
