Sierra 18-8816-1 Spark Plug Wire, Replaces OMC 582365, Johnson/Evinrude, 6 Inch, White

The Sierra 18-8816-1 is a premium replacement spark plug wire lead engineered for Johnson/Evinrude outboard applications. This 6 inch wire uses a Kevlar-reinforced core paired with a durable stainless steel wound conductor, giving the lead the strength to handle continuous engine vibration and heat without breaking down. A premium silicone jacket and matching silicone boots seal out moisture and protect against high engine bay temperatures, while the construction provides superior RFI suppression to keep sensitive onboard electronics running cleanly. Both ends terminate in corrosion resistant stainless steel spark plug and distributor terminals, which maintain solid electrical conductivity even in the humid, salt-exposed marine environment where these outboards operate.

This wire is built as a direct functional replacement for OMC 582365, so it installs using the same connection points as the original equipment wire it replaces. It is supplied as a single wire lead, finished in white, and is part of Sierra's outboard ignition wire program for Johnson/Evinrude engines.
