Sierra 18-28092 V4 Outboard Spark Plug Wire Set for Evinrude Outboards

The Sierra 18-28092 is a V4 Outboard Plug Wire Set built to deliver a clean, reliable spark to each cylinder of a V4 outboard engine, including Evinrude V4 outboard applications. Ignition wires take constant heat, vibration, and moisture under the cowling, and this set is constructed to hold up to that environment while keeping voltage loss and electrical noise to a minimum.

Each wire uses a mag/wire wound core that delivers maximum voltage to the plug while suppressing radio frequency interference (RFI) and electromagnetic interference (EMI), which helps prevent static or interference with onboard electronics. A high-quality conductive center carrier reinforcement maintains conductor integrity over time, while a high tensile strength membrane and an innovative nylon reinforcing tape add durability and resist wire breakage from vibration and flexing. The distributor ends use moisture-proof, molded insulators to keep water and humidity out of the connection points, protecting against misfires and corrosion.

The outer jacket is an 8mm silicone material with high tear strength, rated to protect the conductor at temperatures up to 500 degrees F, making it suitable for the high-heat conditions found around an outboard powerhead. This set is sized and configured specifically for V4 outboard engines; Sierra offers a separate wire set for V6 outboards for engines with a different cylinder configuration.

Frequently Asked Questions

What engines does the Sierra 18-28092 fit? The 18-28092 is a plug wire set built specifically for V4 outboard engines, including Evinrude V4 outboard applications.

Is the 18-28092 the same as the V6 wire set? No. The 18-28092 is configured for V4 outboards; Sierra offers a separate part, 18-28090, for V6 outboards. Order the set that matches your engine's cylinder count.

How many spark plug wires are included in this set? The Sierra 18-28092 is sold as one complete wire set for a V4 outboard engine, with one wire per cylinder.

What material is the wire jacket made from? The 18-28092 uses an 8mm high tear strength silicone jacket that protects the conductor at temperatures up to 500 degrees F.

Will these wires cause radio or electronic interference? No. The mag/wire wound core in the 18-28092 delivers maximum voltage while suppressing radio frequency interference (RFI) and electromagnetic interference (EMI).

How does the 18-28092 resist moisture at the connections? Moisture-proof, molded distributor insulators are used at the connection points to help keep water and humidity out of the ignition circuit.

How durable is this wire set under vibration? The set combines a high tensile strength membrane with nylon reinforcing tape, and a conductive center carrier reinforcement, to resist breakage from engine vibration and repeated flexing.

What connector type do the wires use? The 18-28092 wire set uses male-to-male connectors with a round wire shape.

How much does the Sierra 18-28092 weigh? The 18-28092 spark plug wire set weighs 0.59 pounds.

Are there OEM cross-reference numbers for the 18-28092? No specific OEM cross-reference numbers are published for the Sierra 18-28092; it is identified by its Sierra part number, 18-28092.

Can this wire set be used on engines other than Evinrude? The 18-28092 is built for V4 outboard engines and is associated with Evinrude outboard applications; confirm your engine matches a V4 configuration before ordering.
