Just remember this, there are only TWO types of spark plug wires. Suppression and non-suppression. Suppression wires do exactly what they imply. They suppress (restrict or hold back) enough of the spark so as not to have radio interference. Non-suppression wires are normally some sort of metal core and conduct like a **** at the expense of major radio interference.
This in and of itself is why I never buy "performance" suppression wires, because they are a ripoff, IMO. You can probably find just as good a wire for a street car at your local big box store for half the cost. Besides that, if you don't like them, you can take them back because they all have a lifetime warranty.
