NGK 2097 Spark Plug - Exhaust Side

NGK Laser Platinum Spark Plug 2097

NGK 2097 is a Laser Platinum spark plug built for precise ignition performance in a wide range of import and domestic applications. It uses a platinum center electrode, nickel ground electrode, and a 0.044 in pre-gap to support consistent spark delivery in engines that call for OE-style replacement service.

The Laser Platinum line is part of NGK’s OE-focused spark plug family, backed by the company’s long history as a major original equipment supplier in North America. For drivers servicing older Toyota, Honda, Acura, Nissan, and Chevrolet applications, this plug is a direct choice when matching factory-style heat range, reach, and terminal design matters.

Key Features

• Laser Platinum spark plug with platinum center electrode for stable ignition performance
• 0.044 in pre-gap for listed applications
• 5000 ohm resistor design for ignition noise suppression
• Standard ground electrode configuration with nickel tip material
• Copper core center electrode for efficient heat transfer
• 14 mm thread diameter, 0.75 in reach, and flat seat design
• NGK part number 2097 / BCPR5EP-11

Detailed Description

NGK 2097 is engineered for vehicles that specify a 14 mm, flat-seat spark plug with a 0.75 in reach and a 5/8 in hex. The platinum center electrode helps maintain consistent firing characteristics over extended service intervals, while the standard ground electrode layout supports OE-style combustion chamber fitment. This makes it a practical replacement for applications such as 1987-1991 Honda Prelude, 1988-1991 Honda CRX, 1990-1991 Acura Integra, and multiple Toyota and Nissan models.

Compatible With 1985-1989 Toyota Corolla, 1985-1989 Toyota MR2, 1986-1989 Toyota Celica, 1987-1991 Toyota Camry, 1986-1992 Toyota Supra, and 1989-1992 Toyota Cressida. NGK 2097 also serves select Nissan D21, Pathfinder, Sentra, and Pulsar NX applications, plus 1988 Chevrolet Nova and 1984-1988 Nissan 200SX exhaust-side use where specified. This part cross-references DENSO Auto Parts 4706 and AMS Automotive 4507 for the same application.

What It Helps Address

• Misfire caused by worn or eroded spark plug electrodes
• Hard starting from weak or inconsistent spark output
• Rough idle related to aged ignition components
• Reduced fuel economy from inefficient combustion
• Service replacement for OE-style spark plug maintenance intervals

Installation Notes and Tips

Verify the engine calls for a 0.044 in gap before installation and adjust only if required by the application notes. Confirm thread diameter, reach, seat type, and terminal style match the original plug. For 1984-1988 Nissan 200SX exhaust-side applications, follow the listed dual-plug notes and match the specified gap on all plugs.

Quality Assurance

NGK is a long-established OE supplier with manufacturing and distribution operations supporting domestic and import vehicle coverage across North America and global markets. The 2097 spark plug is built to OE-style standards for durability and consistent operation in the listed applications.
