NGK 8111 Spark Plug Wire Set

NGK Spark Plug Wire Set for OE-Style Ignition Service

The NGK Spark Plug Wire Set 8111 is a specific-fit ignition wire set built for select Nissan and INFINITI applications. It uses blue silicone insulation, a 7.00 mm outside diameter, and a magnetic variable-pitch core with noise suppression to support stable spark delivery and reduced electrical interference.

As part of the NGK Spark Plug Wire Set line, this replacement wire set reflects NGK’s long OE-focused background in ignition components. The RC-NX11 / 8111 application is aimed at drivers servicing ignition systems on vehicles such as the Nissan Sentra, Nissan 200SX, and INFINITI G20.

Key Features

• Specific-fit spark plug wire set for select Nissan and INFINITI models
• Blue silicone insulation for heat and durability resistance
• 7.00 mm insulation outside diameter
• Mag (Var. Pitch) core material for ignition performance
• Noise suppression type: yes
• NGK part number 8111, also referenced as RC-NX11

Detailed Description

NGK 8111 is a replacement spark plug wire set engineered for ignition service on 1994-2002 INFINITI G20, 1995-1998 Nissan 200SX, and 1998-2001 Nissan Sentra applications. It is a specific-fit design, so it matches the listed vehicles rather than serving as a universal wire set. The silicone insulation and noise-suppression construction help maintain consistent ignition signal quality while supporting clean routing in the engine bay.

NGK’s ignition product line is built around OE-level experience and broad vehicle coverage, and this wire set follows that approach with application-specific fitment. If you are replacing worn ignition wires on a Nissan Sentra or INFINITI G20, part number 8111 provides a direct replacement option for the listed model years.

This part cross-references DENSO Auto Parts (e.g., 671-4192, 671-4209) for the same application.

What It Helps Address

• Misfires caused by worn or damaged spark plug wires
• Hard starting related to weak ignition transfer
• Rough idle from inconsistent spark delivery
• Electrical noise in the ignition system
• Loss of performance from deteriorated wire insulation

Installation Notes and Tips

Verify engine application before installation and match the wire routing to the original layout. Inspect spark plugs, distributor components, and coil connections at the same time, since worn ignition parts can affect wire performance. Confirm the NGK 8111 / RC-NX11 part number against the vehicle’s year and model before ordering.

Compatible With 1994 INFINITI G20, 1995-1996 INFINITI G20, 1995-1998 Nissan 200SX, 1998-2001 Nissan Sentra, and 1999-2002 INFINITI G20.
