NGK RC-VWC039 Spark Plug Wire Set - 7mm High Temp Silicone Wires With EMI/RFI Suppression

About This Product

When it's time to replace your spark plug wires, going with NGK is always a smart move - these RC-VWC039 wire sets are built to OEM specifications with all the quality and performance you'd expect from the ignition specialists. The 7mm diameter with 29-gauge galvanized copper core provides excellent conductivity, while that high-temp silicone jacket can handle underhood temperatures up to 482°F without cracking or deteriorating. The variable pitch winding technology is what really makes these stand out - it scrambles and breaks up electrical waves to provide superior EMI/RFI noise suppression throughout a wide frequency range, which means no interference with your radio, electronics, or engine management systems. Each wire is clearly numbered for easy cylinder identification, and the coil wires are color-coded so installation is straightforward without guessing which wire goes where. The terminal ends are corrosion-resistant stainless steel with positive-locking design that ensures a tight fit and maximum resistance to vibration - no more mystery misfires from loose connections. The construction includes high-density fiberglass braiding over EPDM/silicone inner insulation for superior dielectric strength and excellent cable tensile strength. This set includes 4 wires (coil lead not included) and they're designed to provide superior firing for better fuel efficiency and outstanding durability. Whether you're doing routine maintenance or troubleshooting ignition issues, upgrading to NGK wires gives you that peace of mind knowing you're installing quality components that will perform reliably mile after mile.
