Sierra 18-28090 V6 Outboard Spark Plug Wire Set for Johnson/Evinrude - 6 Wires

The Sierra 18-28090 is a V6 outboard spark plug wire set built as a complete replacement for Johnson/Evinrude V6 outboard engines. The set includes a total of six wires, each constructed with a Kevlar core for durability and long life and a stainless steel wound conductor to support maximum horsepower and engine performance. Every wire is covered in an 8mm high tear strength silicone jacket, chosen for its resistance to high under-cowl temperatures, and reinforced with an innovative nylon reinforcing tape for added strength and durability. A high tensile strength membrane adds further heat resistance so the wires hold up under continued engine operation.

Each wire terminates in corrosion resistant stainless steel spark plug and distributor terminals, which maintain strong electrical conductivity even in a marine environment. The distributor end uses moisture-proof, molded insulators to keep water and condensation out of the connection, and a high-quality conductive center carrier reinforcement keeps the conductor intact over time. The mag/wire wound core is engineered to deliver maximum voltage to the plugs while suppressing radio frequency interference (R.F.I.) and electromagnetic interference (E.M.I.), which helps prevent disruption to onboard electronics. This set is designed specifically for Johnson/Evinrude V6 outboard engines and is sold as a matched set of six wires with boot-style connectors.

Frequently Asked Questions

What engines does the Sierra 18-28090 spark plug wire set fit? The Sierra 18-28090 is built for Johnson/Evinrude V6 outboard engines and includes a complete set of six wires for that configuration.

How many wires come in the 18-28090 set? This set includes a total of six spark plug wires, matching the cylinder count of a Johnson/Evinrude V6 outboard.

What is the wire jacket made of? Each wire in the 18-28090 set is covered in an 8mm high tear strength silicone jacket for protection against high under-cowl temperatures.

What is inside the wire, and how durable is it? The 18-28090 wire set uses a Kevlar core along with a stainless steel wound conductor, giving it durability and long life while supporting full engine performance.

Do these wires help with radio or electronic interference? Yes, the 18-28090 uses a mag/wire wound core specifically designed to suppress radio frequency interference (R.F.I.) and electromagnetic interference (E.M.I.).

What kind of terminals does the Sierra 18-28090 use? The set terminates in corrosion resistant stainless steel spark plug and distributor terminals, which maintain strong conductivity in a marine environment.

Are the distributor connections protected from moisture? Yes, the 18-28090 features moisture-proof, molded distributor insulators to keep water and condensation out of the connection.

What are the dimensions of the 18-28090 wire set as packaged? The Sierra 18-28090 spark plug wire set measures 10 x 6 x 3 inches and weighs 0.8375 pounds.

Is the 18-28090 the same set as the 18-28092? No, the 18-28090 is the V6 Outboard Plug Wire Set, while the 18-28092 is a separate part number for a V4 Outboard Plug Wire Set.

Why does the 18-28090 use a nylon reinforcing tape? The nylon reinforcing tape adds strength and durability to each wire in the 18-28090 set, working alongside the high tensile strength membrane for added heat resistance.

Will the 18-28090 work on a V4 or inline outboard? No, the 18-28090 is designed specifically for Johnson/Evinrude V6 outboard engines and is not the correct set for a V4 or inline configuration.

What is included when I order the 18-28090? Ordering the Sierra 18-28090 gets you the complete matched set of six spark plug wires with boots and terminals for a Johnson/Evinrude V6 outboard.
