      NGK Wire Sets are built to meet stringent OEM tolerances for a variety of vehicles. They 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.


      • Superior firing and fuel savings
      • Outstanding durability
      • Consistent performance
      • Excellent noise suppression
      • Perfect fit for your car

      CONSTRUCTION

      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 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.


      At the center of NGK Resistor Spark Plug Wire Sets is a fiberglass stranded core, made from the same family of materials used in bulletproof vests. This core greatly enhances the overall strength of the wire, providing a superstrength backbone on which the various layers of the wire assembly are formed. The core gives protection from damage caused by the pulling strains that wires are often subjected to and that can destroy their performance.


      High-quality EPDM and silicone coverings are used to resist high heat, oil and chemical damage for increased durability.


      Custom-designed terminal boots are always used to provide exact fit (not universal fit like other major wire manufacturers). Each NGK ignition wire is fitted with a positive-locking, corrosion-resistant stainless steel terminal end for tight fit and maximum resistance to vibration and separation.


      NGK Wire Sets are numbered for easy cylinder identification and coil wires are color coded for correct and easy installation.

    • Wire Sets Installation

      STEP 1

      Remove the old spark plug wires, one at a time, replacing them with the new NGK wires. Follow the numbers clearly shown on each wire.

      STEP 2

      Use the existing clamps and follow the original wire paths.

      STEP 3

      Press the boot end of the wire onto the spark plug until it snaps on securely. Insert the other end firmly into the proper terminal on the distributor cap.

      STEP 4

      Install the coil wire: the blue cap end to the distributor, the black cap end to the coil.

      STEP 5

      When removing the wires, pull only on the boot. Do not pull the wires.

    • Are NGK wires 8mm?

      NGK wires are manufactured to the specific dimensions of OEM wires. Most NGK wires are 7mm, while Toyota applications are 5mm where applicable. Most 8mm wires in the aftermarket are merely providing additional insulation, and do not increase the electrical capabilities of the ignition system.

      What is a variable pitch wire?

      NGK uses a variable pitch wire to create the resistance necessary to filter radio frequency interference (RFI) created by an operating ignition system. The variable pitch system alternates tightly wound and loosely wound copper wire around the center of the plug wire to create a magnetic field, creating the necessary resistance with a fraction of the impedance found in a solid carbon-core-type wire set.
