NGK part number 51033 is an ultra-low resistance spark plug wire set designed to provide reliable ignition performance and long-lasting durability. This set includes eight wires and is intended to fit select 2006 GMC Yukon XL 1500, Chevrolet Suburban 1500, and Chevrolet Avalanche 1500 applications. The coil lead is not included. Verify vehicle details and connector configuration before ordering.

Each wire uses a high-temperature premium silicone outer jacket with EPDM and silicone insulation to contain high-voltage current and provide excellent dielectric strength. Stainless steel winding over a premium ferrite magnetic core helps deliver ultra-low resistance for a stronger spark while also suppressing electromagnetic and radio-frequency interference. This construction supports consistent ignition performance in demanding under-hood environments.

NGK spark plug and distributor boots are designed for a secure fit and dependable service. The spark plug boots are bonded to the cable with silicone sealer to help create a watertight connection. Stainless steel terminals use up to three serrated crimps, where possible, to grip the cable jacket and inner insulation for strong terminal retention. A corrosion-resistant locking C-shaped spring clip helps maintain a secure connection at the spark plug terminal.
