Spark Plug Wire Set

Having a high powered ignition control is only half the equation when it comes to your engine's performance, you also need to ensure that the voltage makes it to the spark plug. The FAST FireWire Spark Plug Wire was designed for performance and racing from the inside-out! For FAST, one of the most important aspects of engineering the low resistance FireWire was to ensure it could effectively filter the electro-magnetic interference and "noise" that occurs within spark plug wires. The answer lies within a unique reactive core design that effectively suppresses EMI ensuring trouble-free operation of the ignition control, EFI system and other on-board electronics. From a performance standpoint, the conductor of the FireWire features the lowest resistance, less than 25 ohms per foot, of resistance. Less resistance means the most spark energy reaches the plug gap for every firing. To combat the extreme conditions that wires face under the hood, the core and conductor are protected with a sleeve of double-layered, pure silicone. This design is effective against header heat, oils and abrasion, and to complete the package, our silicone boots can withstand 550 degrees fahrenheit!

Spark Plug Wires, FireWire, Reactive Core, 8.5mm., Black, 135 Degree Boots, Ford/Mercury, Ford, Small Block, Set

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!
