Standard Wires 55112 Spark Plug Wire Set

Ignition Wire Set for OE-Style Performance

Standard Wires 55112 is a spark plug wire set built for direct ignition service on select Ford and Mazda applications. It uses a hi-gloss clear coat over a high-temperature silicone jacket to improve abrasion resistance and heat protection while helping deliver voltage efficiently to the spark plug.

Fits 2003-2004 Mazda 6, N/A; Fits 2005 Mazda 6, N/A, w/ Canada or Federal Emissions; Fits 2008 Ford Fiesta, N/A; Fits 2004-2012 Ford EcoSport, N/A. Standard Wires 55112 is a direct-fit ignition wire replacement for these vehicles.

Key Features

• Patented clear-coat finish with a high-temperature silicone outer jacket
• Core design matched to OE-style wire construction
• Low-ohm, ferrite mag, wire-wound, silicone, or metallic core architecture depending on application
• Improved abrasion resistance for demanding engine bay conditions
• Enhanced voltage transfer to the spark plug
• Improved RFI suppression for cleaner ignition performance

Detailed Description

Part number 55112 is engineered as an ignition wire set for Ford EcoSport, Ford Fiesta, and Mazda 6 applications listed above. The wire construction is focused on maintaining stable spark delivery while resisting heat and wear, making it a practical replacement when original wires show age-related deterioration. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak spark transfer
• Rough idle from deteriorated ignition wire insulation
• Radio-frequency interference from aging ignition components
• Cracking, abrasion, or heat damage on existing wires

Installation Notes and Tips

Match each wire to the correct cylinder routing before removal, and transfer one lead at a time to preserve firing order. Inspect boots, coil connections, and spark plugs during service, since worn ignition components can affect wire performance. Verify vehicle emissions configuration on 2005 Mazda 6 applications before ordering.

Quality Assurance

Standard Wires 55112 is built with materials and core construction intended to meet OE-style ignition service requirements, including heat resistance, abrasion protection, and RFI control.
