ACDelco Spark Plug Wire Set Gold 9718Q (88862381) — 28.2-inch, High-Temp Silicone & Fiberglass

ACDelco Gold 9718Q (88862381) is a premium spark plug wire set built with fiberglass strength and high-temperature silicone insulation for reliable spark delivery and a factory-fit replacement.

This ACDelco Professional spark plug wire set is an aftermarket part engineered to match the fit, form, and function of new-vehicle wiring. Designed to serve a wide range of domestic vehicles, the 9718Q combines a heat-resistant silicone outer insulator with reinforced fiberglass conductors and corrosion-resistant terminals to help maintain consistent ignition performance and long-term durability.

How does this wire set improve ignition reliability?

The Gold 9718Q minimizes signal loss and resists heat-related degradation thanks to its high dielectric materials and robust conductor design. That means more consistent spark transfer under heavy loads and elevated engine temperatures.

• High-dielectric insulator reduces electrical leakage and interference
• Fiberglass-reinforced conductor maintains strength and flex over time
• Corrosion-resistant terminals preserve contact integrity
• Coil retainer prevents fretting and micro-arcing

Will it fit my vehicle and install like OEM wiring?

ACDelco designs its Professional wire sets to match OEM fitment for straightforward replacement. The distributor boot shape and materials are tuned for correct seating and a water-tight seal, helping ensure an OEM-style installation experience.

• Manufactured to match factory wire length and terminal geometry
• Distributor and spark plug boots shaped for secure fit and seal
• 28.2-inch wire length for the specified application
• Compatible with many domestic GM, Chrysler, Ford applications

What materials and design features extend service life?

The combination of silicone insulation and fiberglass reinforcement helps the wires resist cracking, heat aging, and environmental exposure. Durable terminal design and high-quality insulators reduce the risk of arcing, corrosion, and premature failure.

• High-temperature silicone resists oil, heat, and ozone damage
• Fiberglass core adds tensile strength and dimensional stability
• Robust terminals minimize corrosion and ease installation
• Coil retainer secures connection to prevent micro-arcing

How do I know when to replace spark plug wires?

Replace wires when you notice ignition misfires, rough idle, or visible wear like cracked insulation or corroded terminals. Regular inspection during tune-ups helps catch deterioration before it affects engine performance.

• Signs: misfires, poor fuel economy, or unstable idle
• Inspect for cracked silicone, exposed conductor, or terminal corrosion
• Replace as part of routine ignition system maintenance
