NGK Chevrolet Astro 1991-1986 Spark Plug Wire Set

The stainless steel winding over a premium ferrite magnetic core in these NGK wire sets is key to their ultra-low resistance. This design helps deliver a more powerful spark to your engine, which can make a noticeable difference in how smoothly it runs. These wires are built to handle the high voltage needed for ignition, ensuring a consistent and strong spark every time.

NGK uses a high-temperature silicone outer jacket and EPDM/silicone inner insulation to contain that high voltage, giving you excellent dielectric strength. The spark plug and distributor boots are designed to fit just like the original equipment, ensuring a secure connection and long-lasting performance. They're even glued to the cable with silicone sealer for a watertight seal, and the stainless steel terminals use multiple serrated crimps to bite into the cable for strong retention. This set fits a range of vehicles, including Chevrolet Astro, GMC Safari, and Chevrolet C1500 models from the late 80s and early 90s.
