Our High-Performance BLUE 8.0MM Spark Wire Cables specifically for Mercury 2-stroke outboards are well-suited for engines with CDI ignition systems, manufactured between 1976 and 2005 and found on the 2.0 Liter, 2.4 Liter, 2.5 Liter, 150 Black Max, XR2, XR4, XR6, XRI, 175, 200 HP, 225 Pro Max, 260 ROS, 300 Drag, S3000, F1 both Carb and EFI models.

Our WSM spiral wound 8mm pro wires aim to reduce electromagnetic interference (EMI), which is crucial for optimizing the performance of the electronic fuel injection (EFI) system while ensuring maximum voltage to the coil. They include a high-heat 550-degree silicon jacket, high-density Durameter insulation, graphite coating, copper-nickel alloy conductor, ferrite suppression element, and all Kevlar strained inner core.

The wires also come with tight-fitting plug clips and a custom coil boot assembly, providing a secure fit and easy installation, just like Mercury Racing OEM or Quicksilver NGK spark plug wires, without needing coil modifications.

These wires could offer a performance boost in durability and consistent ignition performance for river, racing, and other high-performance applications.

The advantage of using spiral wound 8mm pro wire spark plug wires for a Mercury Racing 2-stroke outboard with a CDI (Capacitor Discharge Ignition) system lies in several key areas:

1. Reduction of Electromagnetic Interference (EMI):

Spiral wound cores consist of tightly wrapped wire around a core material, which helps in reducing electromagnetic interference. CDI systems, along with other electronic components like EFI systems, are sensitive to EMI. By reducing this interference, the spiral wound wires prevent signal disruption, which is critical for accurate fuel injection timing and spark delivery.

2. Improved Ignition Performance:

The spiral wound design allows for high-voltage transfer with minimal resistance, ensuring more efficient spark delivery. This results in a stronger and more consistent spark, which enhances engine combustion. A more reliable ignition can lead to better throttle response, smoother acceleration, and improved engine performance, especially at high RPMs, which is important for high-performance and racing engines.

3. Durability and Heat Resistance:

The 8mm thick insulation of these wires provides greater protection from heat, abrasion, and environmental factors. This is especially beneficial in racing or high-performance applications where engine temperatures are higher, and durability is essential. The thicker insulation also helps to shield against electrical leakage, improving the long-term reliability of the ignition system.

4. Fit and Ease of Installation:

These wires are typically OEM fit, meaning they are installed just like the original equipment wires, making them a plug-and-play solution. The custom coil boot assembly and tight-fitting plug clips ensure a secure connection, which reduces the chance of misfires or loss of spark due to poor connections.

5. Maximizing Voltage to the Coil:

The reduced resistance of the spiral wound wires ensures that the CDI system can transfer maximum voltage to the spark plugs, leading to better combustion efficiency. This is critical for performance-focused engines like the Mercury Racing 2.0, 2.4, 2.5, Pro Max, 260, Drag, and F1 models, where every bit of spark energy counts.

In summary, these wires offer better EMI suppression, enhanced spark energy, greater durability, and easy installation, all of which are important for maximizing the performance and reliability of a high-performance Mercury Racing 2-stroke outboard with CDI ignition.
