NGK 4043 Spark Plug

NGK V-Power Spark Plug 4043 Overview

NGK V-Power Spark Plug 4043 is a direct-fit ignition component built for stable combustion and consistent secondary ignition performance. This NGK spark plug uses a copper center electrode, nickel tip materials, and a standard ground electrode layout to support reliable firing in everyday driving conditions.

The V-Power Spark Plug line focuses on OE-style fit and dependable service life for a wide range of domestic and import vehicles. Part number 4043, also identified as ZFR4F-11, is a practical choice for drivers servicing a 1992-2000 Honda Civic or a 1997-1998 BMW 750iL with the specified factory gap requirements.

Detailed Description

NGK 4043 is engineered as a V-Power spark plug for OE-style replacement service where correct heat range, electrode design, and gap specification matter. The standard ground electrode tip design and nickel materials support consistent spark delivery, while the copper core helps manage heat transfer through the plug body. This makes the plug a straightforward service part for ignition maintenance on vehicles that call for the ZFR4F-11 specification.

Compatible With 1992-2000 Honda Civic and 1997-1998 BMW 750iL applications listed in the fitment data, this spark plug matches the factory-style requirements noted for those vehicles. For Honda Civic service, the OE-recommended 0.044 inch gap is listed for the 30,000-mile service interval. For BMW 750iL service, the listed application calls for a 0.032 inch gap and OE-equivalent design. This part cross-references Autolite 985 for the same application.

What It Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire conditions tied to incorrect plug gap or electrode wear
• Reduced throttle response from degraded ignition performance
• Service replacement needs on Honda Civic and BMW 750iL ignition systems

Installation Notes and Tips

Verify the specified gap before installation and confirm the vehicle calls for the listed heat range and reach. Use the correct 5/8-inch spark plug socket and tighten to the vehicle manufacturer’s torque specification. Check the ignition system, plug wires, and coil condition during service so the new plug can perform as intended. For fitment, use the exact application notes: Fits 1992-2000 Honda Civic, N/A; Fits 1997-1998 BMW 750iL, N/A.
