Have you ever watched your Mustang's ignition system in the dark with the engine running? Because ignition systems produce 20,000 to 50,000 volts of high-energy electricity, a certain amount escapes all the time, resulting in a light show under the hood at night. When spark plug wires get close to each other and close to ground, there's arcing you cannot see in daylight. The stray voltage isn't enough to cause misfires, but sacrifices are made in terms of spark intensity. When you lose current to ground or to another spark plug wire, you're not getting a potent spark at the cylinder on compression/ignition stroke.
Made 4 You Products understands the temperamental nature of ignition systems and high-voltage electricity. It also understands what looks good. That's why Made 4 You conceived Smoothie spark plug wire separator kits for 7-8mm ignition wire sets. These kits keep spark plug wires separated and uniformly rooted while maintaining a neat, clean appearance. They're priced right at $52.95 for a basic V-8 set.

Made 4 You Smoothie wire separators...

Made 4 You Smoothie wire separators look terrific on any engine application because of their outstanding quality, heat resistance, and ease of installation. We decided to go with black (PN 50-35611) and blue (PN 50-35612) on two small-block Ford applications. These are Smoothie Top Mounts. They're also available as a Vertical Wire Loom Kit (PN 50-71011 through 50-71019 series) that offers tighter wire flow in tight spaces.

Installation begins with pedestals...

Installation begins with pedestals in place of valve cover bolts. Remove the affected valve cover bolts and install these pedestals using a 3/16-inch Allen wrench.
