Cdi Electronics Spark Plug Wire Set for MerCruiser I/O Engines

CDI Electronics marine spark plug wire sets are replacement ignition wires for MerCruiser sterndrive (I/O) engines. They are also called plug wires, ignition wires or spark plug cables. They carry high-voltage current from the distributor or ignition system to each spark plug. This helps the engine start reliably, run smoothly and use fuel efficiently.

Key Features:

• Premium silicone jacket over dense EPDM insulation for strong dielectric performance and heat resistance
• Capacitance, inductance and resistance are tuned for efficient spark energy transfer
• Electrical properties that suppress EMI, which helps protect radio and electronic ignition performance
• Corrosion-resistant terminals suited to the marine environment
• Silicone boots that resist heat, abrasion and chemicals
• Wire sets are made for specific engine and ignition configurations, with matched wire lengths and boot styles

CDI Electronics has long supplied ignition components to the marine and motorsport industries. Each set is a direct-fit replacement that restores ignition performance during a tune-up or when worn, cracked or corroded wires need replacing. Choose the specific part number that matches your engine and ignition system.
