MSD 8.5mm Super Conductor spark plug wire sets feature a special helically wound core that has just 40-50 ohms of resistance per foot—but with an RFI suppression equal to a 1,500 ohm wire. In fact, each foot of finished wire includes 40 ft. of tightly wound copper for superior conductivity. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective Electro Magnetic Interference "choke." This choke, or suppression capability, keeps the EMI inside the wire where it cannot interfere with other electronics on your vehicle. A tough, 8.5mm synthetic/silicone jacket over an extra-heavy glass braid and dielectric insulator keeps the current guided to the plugs. Underneath the high-temperature boots, dual crimp stainless steel terminals feature snap-locks to ensure a secure fit. Each set comes with clip-on cylinder markers for easy identification. MSD's 8.5mm Super Conductor wire sets are available in custom or universal-fit applications.

Q:

The question concerns the length of wire supplied in the set.
I would like to run the wires from distributer under the exhaust manifold to the plugs. I purchased a standard set that does not allow length to run under the manifold for all plugs. All plug wires will be different of course but should be long enough to fab 8 custom lengths. What is the length of the wire supplied.
and is it one length?

Asked by GLEN on April 14, 2017

A:

They are different lengths but you will have plenty of wire to run under as that is what I have done, under my headers. These are great spark plug wires, you will be glad you got them.

Q:

Will these work with a pro
Billet distributor cap

Asked by EDWARD on June 10, 2019

A:

Edward, as long as your distributor cap has metal terminals coming out of the top that look like a spark plug end, these wires will work.

Answer This Question

Q:

Will these wire work with a MSD Pro-Billet Ready-To-Run Distributors 8360 on my 327 SBC? And are they long enough to run over the valve covers?

Asked by RON on December 26, 2018

A:

I just put a set of these on a 57 Chevy with a 350 sb. I actually ran them under the headers and back behind the cylinder heads and up to the distributor. I had wire left over! There could be an application where they are too short but I find that hard to imagine.

Perfect for running wires where you need

I have an old 79 blazer that these wires went on. The fact that you get to cut and build these wires the length you need says it all. Any route you need to take with your wires can now be done and they even come with a tool to build them properly. For just a few dollars more these wires were exactly what I needed and they are superb quality. I could instantly feel more power with these. I would recommend this item to anyone who puts quality in their ride. ...read more

Excellent Spiral Core Wire

Summit RacingSummit Racing Verified Purchase

MSD-31229
I've used these wires for over twenty years on one vehicle and they have never needed replacement. The boots are great and the wire insulation is also. They won't leak using aftermarket high voltage ignitions as long as they have been assembled properly using the included tool. They also effectively suppress EMF and cross induction. The boot design on this model is also good for small block Chevy angle port heads and most headers. The wire lengths are long enough for a number of wiring arrangements for good wire placement. Both HEI and conventional style distributor boots are supplied in the package with the correct metal terminals. ...read more
