- NGK spark plug wires are the perfect compromise between stock replacement reliability and performance wires! NGK wires use the same spiral wrap design of many high performance wires are made from, giving you unsurpassed conductivity for a hotter spark. What sets NGK apart is that they wrap the core in a "Variable Pitch" winding. Using a loose to tight to loose method breaks up radio frequency interference and electromagnetic interference. This design not only reduces radio static, it also reduces interference your vehicles computer, ignition system and electronically controlled equipment may experience with other wires.
