There is a ton of " voodoo", mystery, and over zealous salesmanship in the spark plug wire industry. The Magnecor stuff is great product, with people that tell it like it is. They are a very unique company, that prefers not to be mainstream, but the quality and knowledge is 100% top notch.
There is a lot of bad information out there, almost always 99.5% directed to make you buy ( insert name of wire company here ("their") wires. They bank on people getting all excited about marketing pitches, colors,silicon this and that, trick boots and "XX" mm wire.I used to know a guy on a top fuel team that loved telling the story of how they got a supplier to GIVE them wires for free.( Which is quite common with these teams) Hell, if the wires would/could only lasted one run, why would they care, they got them free anyhow. They would put on whatever you wanted, and then the supplier could advertise accordingly. There goal is almost always to sell a set of wires regardless of the real need. Sell baby sell. We need a smoke and mirrors graemiln now....
