NGK 7086 Spark Plug - Exhaust Side

NGK G-Power Spark Plug 7086 Overview

NGK G-Power Spark Plug 7086 is a direct-fit ignition component built around a platinum center electrode, nickel ground electrode, and a 5,000 ohm resistor for stable secondary ignition performance. It is a practical OE-style replacement for a wide range of import and domestic applications, including Toyota Corolla, Honda CRX, and Nissan Sentra service needs.

The NGK G-Power line focuses on dependable ignition performance with durable electrode materials and OE-level manufacturing standards. Part number 7086, also identified as BCPR5EGP, uses a flat seat, 14 mm thread diameter, 5/8 hex, .750 reach, and a .040 pre-gap specification.

Key Features

• Platinum center electrode tip for consistent spark delivery
• Nickel ground electrode with trapezoid tip design
• 5,000 ohm resistor for ignition noise suppression
• Copper core center electrode for heat transfer
• Flat seat design with 14 mm thread diameter and .750 reach
• Pre-gapped to .040 inches
• NGK part number 7086 / BCPR5EGP

Detailed Product Description

NGK 7086 is engineered for drivers and technicians who need a reliable spark plug for older Toyota, Honda, Nissan, Acura, Geo, Saab, and Chevrolet applications. The platinum-tipped center electrode supports steady ignition performance, while the copper core helps manage heat under normal operating conditions. The 5,000 ohm resistor helps reduce electrical interference in the ignition system.

This part cross-references DENSO Auto Parts 4706 for the same application. For fitment-based searches, this spark plug is commonly selected for 1988-1992 Toyota Corolla, 1988-1991 Honda CRX, and 1989-1990 Nissan Sentra service work. Part number 7086 is also a useful reference when sourcing NGK BCPR5EGP replacements.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark output
• Misfire conditions related to aged ignition components
• Reduced throttle response from weak combustion events
• Ignition noise concerns in resistor-equipped systems

Installation Notes and Fitment Tips

Compatible With 1992-1994 Saab 900, N/A; 1988-1993 Toyota Celica, N/A; 1990-1992 Geo Prizm, N/A; 1988-1992 Toyota Corolla, N/A; 1989-1992 Toyota Cressida, N/A; 1986-1992 Toyota Supra, N/A; 1990-1991 Acura Integra, N/A; 1988-1991 Honda CRX, N/A; 1987-1991 Toyota Camry, N/A; 1988-1990 Honda Prelude, N/A; 1989-1990 Nissan Pulsar NX, N/A; 1989-1990 Nissan Sentra, N/A; 1986-1989 Nissan D21, N/A; 1987-1989 Nissan Pathfinder, N/A; 1985-1989 Toyota MR2, N/A; 1988 Chevrolet Nova, N/A; 1984-1988 Nissan 200SX, Exhaust Side; and 1988 Toyota 4Runner, N/A.

Verify the specified gap for the vehicle before installation, since several listed applications call for a gap different from the .040-inch pre-gap. The 1984-1988 Nissan 200SX exhaust-side application requires attention to the OE dual-plug arrangement and the notes provided for that engine configuration. Use the correct torque procedure and confirm thread reach, seat type, and terminal style before final installation.
