Massive MSX80 Spark Plug Wires Zetec w/ MSD coil side Ignition Wires 00-04 Ford Focus MSX80Install in place of small factory wires. REALLY improves spark characteristics. Expect a smoother idle, MORE horsepower, and even a little better gas mileage! Missive's pure power silicone wires are not only good looking but have far lower resistance than other wires. These wires have an extra thick boots for excellent life and to keep the elements from corroding the contacts. Each wire has its own wire number marker and an included wire loom separator to keep the wires tidy and looking good. Dielectric grease is included to ease both installation and future removal. Quality made in the USA!!! Very straight forward installation. If you need assistance, let us know and we’ll walk you through it! Should take less than 20 minutes for a novice car guy (or girl).
