Sierra 18-5229-9-1 Spark Plug Wire Set, 22 Inch, 7mm Copper Core, Pack of 5

The Sierra 18-5229-9-1 Spark Plug Wire Set is a package of five 22 inch ignition wire leads built with 7mm copper core wire for marine engines. Each lead uses a Kevlar core for durability and long service life, paired with a stainless steel wound conductor to support consistent voltage delivery and engine performance. The wires are finished with premium silicone jacketing and boots, giving the leads high temperature protection at the plug and coil connections. Corrosion resistant stainless steel spark plug and distributor terminals maintain solid electrical conductivity in the marine environment, while the wire construction is designed to suppress RFI so it does not interfere with sensitive onboard electronics.

This set ships as a pack of 5 wires at 22 inches in length with a 7mm copper core, making it suited to engines that require this wire length and gauge. The male-to-male round connector design allows for straightforward installation in place of worn or cracked ignition leads.
