Standard Wires 55908 Spark Plug Wire Set

Ignition Wire Set for Toyota 4Runner and Pickup

Standard Wires 55908 is a spark plug wire set for select Toyota 4Runner and Toyota Pickup applications from 1988 through 1991. It is built with a hi-gloss clear coat and high-temperature silicone jacket to help protect the wires in demanding engine bay conditions.

Key Features

• Patented clear-coat outer finish for added abrasion resistance
• High-temperature silicone jacket for heat protection
• Enhanced wire core design matched to OE-style requirements
• Low-ohm, ferrite magnetic, wire-wound, silicone, or metallic core construction depending on application
• Improved voltage transfer to the spark plug
• Enhanced RFI suppression for cleaner ignition performance

Detailed Description

Standard Wires part number 55908 is engineered for ignition systems that need reliable spark delivery and durable insulation. The wire set channels maximum voltage to the spark plug while helping reduce radio-frequency interference, which supports stable engine operation in compatible Toyota 4Runner and Toyota Pickup models. The protective outer coating and silicone jacket add resistance to abrasion and severe temperatures, making this a practical replacement for aging ignition leads.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition leads
• Interference issues linked to poor RFI control
• Cracking, abrasion, or insulation breakdown on older wires

Installation Notes and Tips

Verify routing against the original wire layout before installation to maintain proper firing order and clearance from hot or moving components. For best results, inspect distributor cap, rotor, and spark plugs at the same time, since worn ignition components can affect wire performance. Fits 1988-1990 Toyota Pickup, N/A; Fits 1990-1991 Toyota 4Runner, N/A; Fits 1989 Toyota 4Runner, N/A; Fits 1991 Toyota Pickup, N/A, to 8/91.

Quality Assurance

Standard Wires 55908 is built to OE-type core specifications and uses heat-resistant materials for consistent ignition performance in Toyota 4Runner and Pickup applications.
