Plug Wires for DUI

For my '91 BFN's 454, I used the same stock wires the Pro Tec used and have not yet upgraded the spark plug wires. It runs noticeably better than the Pro Tec.
I think new wires are very pretty...................Necessary? I'm not so sure.

Pick up a Taylor kit from summit or Jegs. Spiral 8mm wires. The DUI wires are very nice but you need to give them custom measurements because their stock kits don’t work.

In the 50's and 60's wires were commonly changed at tuneup time. Early wires were cloth, later were a synthetic called Hypalon. High energy systems starting in the 70's needed better insulation that's when silicone started being used in the wires and boots themselves. I remember Accel wires being the big thing in the mid 70's. It was when these new wires came out that they were not changed automatically during a tune up. Matter of fact the tune up that was done religiously every fall was a thing of the past too. A reputable shop would only change a wire if it were bad or damaged when removed. I'll bet Pete has some really old wires on something........

Napa stocks and sells a brand named Belden/Powerpath.   It is very good wire and not expensive. You may need to search or get them to dig through the catalog to see what lengths are needed and with what ends attached. The catalog shows all this information.
Go into the store with details.   Know how long each of your 8 need to be and if you want 90 degree or straight plug ends, with a little digging you will find a set.
I did it on my GM 350 in a Malibu and on my brothers Supra with a PCM 351W we found nice wire sets for each when converting to High energy distributors.
These sets are not flashy but are made from high quality wire that works.
If I remember correctly Standard Ignition bought Belden from Federal-Mogul about 15 years back but Napa still distributes this product last I knew.

Here's a chart for Taylor universal Spiro Pro wires complete with part numbers for about every color you might want plus some you shouldn't ever want   

With 90 degree boots you can't go wrong

And then you'll need a crimping tool to go with the universal wires

There are plenty of other companies with spiral core wires out there too

I used purple wires.

I love colored wires. We've got yellow on one boat, red on another and some brand new oranges ones for the next boat.

Taylor Pro gets the nod-color still up in the air-thanks for the suggestions
