NGK 55008 Spark Plug Wire Set

Ignition Wire Set Overview

NGK Spark Plug Wire Set 55008 is a specific-fit ignition wire set built for classic Mazda rotary applications and Fiat small-displacement models. It uses silicone insulation, a blue outer jacket, and noise suppression construction to support stable ignition performance and reduced electrical interference.

Key Features

• Specific-fit spark plug wire set for direct application matching.
• Silicone insulation for heat resistance and flexible routing.
• Noise suppression design helps reduce radio-frequency interference.
• SMag core material supports consistent spark delivery.
• Blue insulation for easy visual identification during service.

Detailed Description

NGK 55008 is part of the NGK Spark Plug Wire Set line, a product family backed by the brand’s long OE-focused ignition experience. This set is engineered for vehicles that need a precise replacement ignition lead solution, including Mazda Cosmo, RX-3, RX-4, Rotary Pickup, and RX-2 applications, as well as Fiat 850 and Fiat 600D fitments. The combination of silicone insulation and noise suppression construction makes it a practical choice for maintaining ignition integrity in older vehicles where wire condition directly affects drivability. This part cross-references DENSO Auto Parts 671-4013 for the same application.

What It Is Used For

• Restoring weak or inconsistent spark transfer.
• Addressing ignition misfire caused by aged wire insulation.
• Reducing electrical noise that can affect engine operation.
• Replacing cracked, brittle, or heat-damaged ignition wires.
• Servicing classic Mazda rotary and Fiat ignition systems.

Installation Notes and Tips

Verify the wire routing and terminal layout against the original setup before installation. Confirm the application by vehicle year, make, and model, since this is a specific-fit part number 55008 and not a universal set. Inspect related ignition components such as plugs, cap, and rotor during service to avoid repeat ignition issues.
