I think, I'm gonna order a set of Magnecor KV85 wires. Any-one put a set on their car? Would there be any improvements, besides looking cool. Pros & cons.........Thanx.

 

no improvement over new normal plug wires.

 

I'm inclined to agree.

Many have switched to kv85's only to experience bad connections whilst driving.

Be sure to use dielectric grease and some slight extra crimping may be required.

 

We are a distributor for them and have installed them on quite a few cars.

When installing you really have to listen for the click as it is not as audible as the OEM ones. They provide a much thicker wire and are so much easier to get on and off compared to the stock ones. For that reason alone I would get them. Plus we can get them for like 145.00 shipped per set.

If you haven't already changed your plugs do it while you change your wires as it will avoid having to go through the process twice.

Here's a link to the plugs and wires: http://www.tvtdesign.com/inc/sdetail/527

And just wires:

I haven't had any problems with my magnecor wires. I had them professionally installed tho. As far as felling any kind of differense afterwards, I couldn't really tell. Although to be fair I had my plugs, pulley, and tune all done at the same time so...

 

I think the length of the factory wire is too short, for you to see any gains

 

Huh Can you clarify?

 

The distance from the coil pack to plug is a short run so you don't loose spark. A thicker wire offers less resistance so you get a better spark and this was more beneficial in the day when spark plug wires were longer, like in the 1977 Trans Am (yea I owned one). With our cars running individual coil packs per cylinder and short run wires you will not gain a greater spark where you will see any difference in horsepower. Did that help

 

I find it surprising that one would expect to "feel" a difference just by changing plug wires? Get real, horse power doesn't come that easy. I run magnicores on my SRT for simply for the common sence of it all. When your pushing over 400hp out of a six you can't but improve spark/performance with large guage wire. It's why you can't cut corners and obtain h/p. When you have done all the major modifications that cost $$$, then throw in a set of 8.5mm wires but until then save your change.

 

If you are going to be changing the plugs change the wires anyway out of ease of install, they are cheap enough.

 

Do the magnecor wires come with the heat shield like our factory wires?

 

In some cars, you can actually feel the difference but several things combined would aid in the performance gain. Like Bulldoger mentioned, the length does make a difference if you are changing out old, inferior wires made years ago compared to the latest design with near zero resistance. In theory, you would be able to open up the spark plug gap somewhat due to increased spark energy. In our cars, there is not enough spark travel even with average wires to realize a gain.

No but the boot is extremely thick.

 

The electrical engineer inside of me is cringing and dying a little bit each time a new post is made on this subject.

1. Spark plug wires carry high voltage, low current, meaning that the total transmission loss is very low.
2. Some of the physics stated about lower wire resistance is true, but only if you are trying to transport 300KW of electricity from Riviera Beach Florida to Amherst Massachusetts. Between a coil pack and a plug, to fire a spark plug, the total wire loss is probably on the order of nanoamperes.

 

I agree. Where it did make a slight difference for me was in a 1991 GMC truck with a slightly modified 350. I changed out the coil for a Jacobs Electronics Ultra coil along with their zero resistance wires. I gained a whole wopping 3 HP for about $250 so it was not worth the money. The original coil and wires were fine so it was a good comparison.
