WTF are you guy's talking about?
Can't find any reference to them!
What are they, why change, you can't see plug wires anyway?
It's because of the EMI suppression. These wires are supposed to have it, but it's in a form (twisted carbon weave) that can wear out over time. Also, they can come not suppressed right out of the box. Another set could possibly fix it for you as they're hit/miss. They ALL will cause issues over time as the suppression wears out. Basically if the carbon weave doesn't make a full connection from cap/cap in the wire it's worthless. Over time, the carbon deteriorates or comes loose from the caps. The spark travels along actual metal core, the carbon is just for EMI suppression.
There is some speculation that incorrect wires will actually fry sensitive electrical components (think EHC!). There are a few jap cars that guys have run non-suppressed wires on and have been killing their throttle position sensors...the EHC is too far away, but the electrical interference could run back to the EHC through any wire if things aren't grounded properly.
Search Magnecor, I think Don is doing a group buy as well. I did tons of research on the issue and figured out what the problem is. Our electrical systems are just so sensitive and if the wires emit any interference it'll pick up in the tach first as it's run off the coil which is obviously closest to the wires.
You will see NO performance increase with different wires unless your old ones were bad.
for everyone here is their info:I e-mailed these guys last night and looked up their ebay add found their phone number on the ebay store site and will call them this morning, these critters look pretty awsom fat and bright blue, my problem with them is the coil plugin on my S&S is a very small steel peg and the one one the wires are the size that fits cars. at $60 bucks, when they do fit i think the looks will be worth it .....
I believe the tach redline at idle is a low voltage issue.Got them also. Looks great but at idle the Tach red lines as when does at low idle with the other wires. No performance loss so I'm keeping them on. Anyone know why that happens?
