Spark Plug Wires

bcfitzsimons · February 17, 2003

Does anyone know of a good brand of spark plug wire for the 8.1L? I called Summit Racing, and all they could suggest was Taylor, who doesn't make them for the 8.1L.

Has anyone changed out the wires in theirs yet? Any suggestions?

Thanks-Fitz. :thumb:

They're all good. Taylor is good, MSD is good (and my preferred choice), Accel, Magnacor....albeit I had problems with teh Magnacor's being too short on my LS1 and popping off the plug and shorting out. At which time I switched back to MSD.

Problem is, no one has anything out for the 8.1. I've been eagerly watching for a set of 8.1 wires from anyone (preferably in blue). You could always buy just the wire itself and make your own connectors and boots. It's not that hard.

ya, msd sells individual super conductor wires for about $14 each, all you need to do is cut to length and crimp on the terminel end.

That's what I figured that I had to do. What's the best choice in terms of wire characteristics? Low resistance, like 150 ohms? Or will that cause too much RF interference and screw with the fuel injection system and engine computer?

Thanks-Fitz

msd's wire are rated at 40ohms of resistance per foot, and the accel spiral core super stock wires i have are about 150 ohms per foot, which yields greater spark energy at the plug and less chance of misfire. most of the good wire brands(msd, accell, taylor) have excellent rfi suppression, & silicone outer jacket that'll last a long time, longer than oe wires.

msd wires claim to have rfi suppression equal to wires of 1500 ohms resistance per foot.
