NGK Lifetime Warranty Ignition Wire Set, ZE02 NGK Fits select: 1986-1991 MAZDA RX7

NGK Ignition Wire Set NGK 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. A 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 versus 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. Features and Benefits: 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.
