Product Details

NGK part number 2869, also identified as UR4GP, is part of the G-Power Spark Plug line. NGK is a long-established OE supplier with broad coverage across domestic and import vehicles, and this spark plug reflects that background with original-equipment-focused construction and durable materials. The platinum tip helps maintain consistent ignition performance, while the copper core supports efficient heat transfer. This makes it a practical choice for older engines that call for a tapered-seat 14mm spark plug with a .046-inch reach.

Compatible With long-tail applications such as Fits 1975-1996 Ford E-350 Econoline, Fits 1973-1996 Ford F-250, and Fits 1976-1986 Chevrolet Caprice. It also appears in fitment for many Chevrolet Camaro, Pontiac Firebird, GMC Jimmy, and Ford Bronco applications, making NGK 2869 a strong match for owners servicing classic V8 and light-duty truck platforms.

This part cross-references Autolite AP25 and Bosch 6712 for the same application.

Installation Notes and Tips

Verify engine-specific gap requirements before installation. Although the plug is pre-gapped to .040 inches, many listed applications call for different settings such as .035, .044, or .045 inches. Check the vehicle service specification for your exact year, make, and model, then adjust the gap as needed before installation. Confirm tapered-seat compatibility, thread diameter, reach, and hex size before use.
