Nology HotWires are the most technologically advanced ignition wires available. Nology HotWires are spark plug wires that create the most powerful spark possible thanks to a patented capacitor and grounding system that are incorporated into each spark plug wire. These are no ordinary plug wires. You will experience a more complete spark with Nology spark plug wires, resulting in increased horsepower. The increased fuel economy alone, due to the increased combustion, will pay for your new set of Nology wires over time! The patented and revolutionary design Nology Hotwires feature allows energy from the ignition coil to accumulate in the Nology capacitor (inside the Nology Spark Plug Wire) until the voltage at the spark plug electrode reaches the ionization point. At that split second point the entire power of the stored spark is discharged at once, creating a spark 300 times more powerful. The result is faster, more complete combustion, and most importantly, more horsepower. What's in it for you when you put Nology Hotwires Spark Plug Wires on your vehicle? Faster engine starts, smoother idle, increased fuel economy, increased acceleration, 2-5% increased horsepower, increased torque, higher rpm limits, and lower exhaust temperature and emissions! Nology Spark Plug Wires pay for themselves over time! The part number for this Nology Hotwires Spark Plug Wire is 012-001-081 and it is Universal 26" Long 90 Degree Boot (for Motorcycle/ATV).
