NGK Spark Plug Wire Set (51003) for Select 1998-2007 Chevrolet, GMC, Isuzu, and Oldsmobile

Fits select 1998-2007 Chevrolet, GMC, Isuzu, and Oldsmobile models, including Astro, Blazer, S10, Sierra, Savana, and Safari.

The NGK 51003 spark plug wire set is engineered to provide maximum conductivity and durability for GM-based ignition systems. Utilizing an ultra-low resistance ferrite magnetic core, these wires deliver a more powerful spark for efficient combustion while providing superior EMI/RFI noise suppression for onboard electronics. The construction features a high-temperature silicone outer jacket and EPDM/silicone inner insulation to maintain high dielectric strength and resist chemical degradation in the engine bay.

Designed for a precision fit, the spark plug boots are glued with a silicone sealer to ensure a watertight seal. Stainless steel terminals with up to three serrated crimps bite into the jacket for high retention strength, while the locking C-shaped spring clip ensures a positive connection to the spark plug tip.
