Sierra 18-8815-1 Wiring Plug Set - Ignition Wires for Evinrude Outboard Engines

The Sierra 18-8815-1 Wiring Plug Set is an ignition wire set built for Evinrude outboard engines. Each wire uses a stainless steel wound conductor for consistent conductivity and reliable engine performance, paired with a Kevlar core that adds durability and long service life under the vibration and heat typical of marine ignition systems. The spark plug and distributor terminals are made of corrosion resistant stainless steel, which helps maintain a solid electrical connection in the marine environment where moisture and salt exposure are constant concerns. Premium silicone jacketing and boots wrap each wire and terminal connection, providing high-temperature protection close to the engine block and exhaust components. The set also delivers superior RFI suppression, reducing electrical interference so onboard electronics and sensitive instrumentation run without disruption. Each wire measures 4 inches (101.6 mm) in length. This wiring plug set is a direct fit for Evinrude outboard engines, making it a straightforward replacement when ignition wires have degraded from heat, vibration, or corrosion.
