With a rating of 25 ohms per foot, FAST FireWire spark plug wires are a whopping 37 percent more efficient than the nearest competitor. These premium-grade, double-layer, silicone-insulated wires offer unsurpassed resistance to heat and damaging fluids and enhanced protection against high-voltage breakdown. They are also ideal for street use, as their KEVLAR®-reinforced "reactive core" design filters out RFI and EMI noise that affects sound systems.

Additional features include:

* Unique reactive-core engineered to deliver maximum spark-gap energy to your spark plugs with today's high-output competition ignitions
* Filter out RFI and EMI (RFI/EMI pulsings confuse onboard engine control computers, audio systems, and other electronic devices)
* Very low 25 ohm resistance ensures maximum spark-gap energy is delivered to the spark plugs
* Complete, assembled, and ready to install!
