NGK Ignition Wire SetNGK Resistor Spark Plug Wire Sets utilize a construction method known as "variable pitch" wire winding to create resistance to radio frequency interference. The variable pitch winding (loose/tight/loose) provides suppression throughout a very wide range by "scrambling" and breaking up the electrical waves radiated by the firing of the spark plugs.NGK Spark Plug Wire Sets are built to meet stringent OEM tolerances for a variety of import vehicles OE-Equivalent. OEM style connectors for easy Installation. Superior Firing and Fuel Savings Outstanding Durability and Performance Excellent Noise Suppression Numbered for easy cylinder identification. High quality EPDM and Silicone coverings.CONSTRUCTIONA ferrite magnetic layer consisting of a mixture of rubber, plastic and powdered ferrite magnetic materials, offers uniform resistance and unsurpassed conductivity. NGK wires have a lower resistance than conventional carbon core wires (8k ohm/meter vs. 16k ohm/meter). This comparison is important to remember when you consider that many manufacturers recommend wires be replaced when the resistance exceeds 20k ohm/meter. This does not leave much margin for wear when the wire may only meet original standards at the very early stages of its life.Warranty Information: 12 Month - 12,000 mile limited warranty against defects in material and workmanship.KRX011 NGK.
