Detailed Description

NGK 9175 is part of the NGK Spark Plug Wire Set line, a product family backed by the brand’s long OE-focused ignition experience. The wire set is engineered for select Chevrolet Sprint, Geo Metro, and Pontiac Firefly applications from 1989 through 1991, with 1991 coverage limited to vehicles built to 5/1991. The silicone outer jacket and noise-suppression construction make it a practical replacement for ignition service where stable spark transfer and reduced interference matter. The NGK 9175 part number is also referenced as RC-SE80.

What It Helps Address

• Misfires caused by worn or damaged ignition wires.
• Electrical noise that can interfere with ignition system operation.
• Cracked or heat-aged wire insulation.
• Weak spark transfer from deteriorated wire cores.
• Service replacement needs for aging ignition components.

Installation Notes and Tips

Verify engine application and production cutoff before ordering, especially for 1991 models marked to 5/1991. Match each wire to the correct cylinder routing and inspect related ignition components during installation. Confirm the NGK 9175 / RC-SE80 reference against the vehicle’s original wire set before service.
