NGK Chevrolet Caprice 1990-1989 Spark Plug Wire Set

NGK is known for making reliable ignition components, and these spark plug wire sets are no exception. If you're working on your 1989 or 1990 Chevrolet Caprice and need to replace the spark plug wires, this set is built to get the job done right. These wires are designed to handle high voltage currents, ensuring a strong spark reaches your plugs for better engine performance.

What makes these wires stand out is their construction. They feature a stainless steel winding over a premium ferrite magnetic core, which results in ultra-low resistance. This means a more powerful spark and less electrical interference, helping your engine run smoother. The outer jacket is made of high-temperature silicone, and the inner insulation uses EPDM and silicone for excellent dielectric strength, keeping that high voltage contained. The spark plug and distributor boots are made to OE specifications, so they fit securely and provide a durable connection. NGK even glues the spark plug boots to the cable with silicone sealer for a watertight seal, and the stainless steel terminals use multiple crimps for strong retention.

When installing, you'll find the OE-spec boots ensure a good fit, and the locking spring clip on the spark plug terminal makes for a secure connection. This set is a solid option for restoring your Caprice's ignition system to its proper working order.
