NGK 2298 Spark Plug

NGK Racing Spark Plug 2298 Overview

NGK Racing Spark Plug 2298 is a copper-core, nickel-tip spark plug built with a standard ground electrode design, a flat seat, and a 14 mm thread diameter. It uses a 13/16 hex, a .375 reach, and a .032 pre-gap size for straightforward service in applications that call for this specification.

NGK’s racing spark plug line focuses on consistent ignition performance and OE-level manufacturing quality, backed by the company’s long history supplying spark plugs for domestic and import vehicles. Part number 2298 is also identified as R5670-5.

Key Features

• Copper center electrode core with nickel center electrode tip
• Nickel ground electrode core with standard ground configuration
• Resistance: 1
• Manufacturer heat range: 5
• Flat seat design with non-removable nut terminal
• 14 mm thread diameter, .375 reach, 13/16 hex
• Pre-gapped to .032 for applications that specify this setting

Detailed Description

NGK 2298 is a racing spark plug engineered around a conventional electrode layout that supports stable spark delivery in properly matched ignition systems. The copper core helps manage heat transfer, while the nickel electrode materials provide a durable firing surface for service in performance-oriented and OE-style applications. If you are searching for an NGK spark plug 2298 replacement or comparing R5670-5 against other ignition parts, this plug is built around standard dimensions that matter for fit and function.

This part cross-references Champion Spark Plug 10 for the same application. It is a practical choice for drivers and technicians looking for a spark plug for Honda Civic, Toyota Corolla, or similar vehicles where the listed thread, reach, seat, and terminal style match the engine specification.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Misfire conditions from weak or inconsistent ignition output
• Rough idle related to degraded plug electrodes
• Reduced throttle response from incorrect spark plug specification
• Service issues when replacing a plug with the wrong reach, seat, or hex size

Installation Notes and Tips

Verify the engine’s required thread diameter, reach, seat type, and terminal style before installation. Confirm the gap specification against the vehicle service information, even though this plug is pre-gapped to .032. Use proper torque procedures and inspect the ignition system, including wires or coils, if the original plug showed signs of fouling or overheating. For fitment-based searches, this NGK 2298 spark plug should be matched to the exact engine application rather than selected by vehicle name alone.

Quality Assurance

NGK is a long-established OE spark plug manufacturer with broad coverage across domestic and import vehicle applications. Part number 2298 reflects that manufacturing background and is built to the dimensional and material standards listed above.
