Deliver coil voltage to every spark plug with a Miata spark plug wire set built to factory form: the DENSO Auto Parts Spark Plug Wire Set 671-4269. It is a direct-fit replacement for the 2001-2005 Mazda Miata with the L4-1.8L engine. DENSO describes its First Time Fit ignition wire sets as identical in form, fit, color and performance to the wire sets installed at the factory.

  • Reinforced construction: A Kevlar®-reinforced core, EMI/RFI suppression layers and a Class E silicone jacket are designed to provide strength, conductivity and heat resistance.
  • OE/OES standards: DENSO states that every part of each set's construction meets or exceeds OE/OES standards.
  • 5 mm wire: The insulation outside diameter is 5.00 mm.
  • Terminals and boots: Male terminal at the coil end, and a female terminal with a 180-degree boot at the spark plug end.

Spark plug wires carry high-voltage current from the ignition coil to each plug. Heat and age can crack or harden the insulation and loosen the boots. Signs your Miata plug wires may need replacing include misfires, a rough idle, hesitation on acceleration, and visible cracks or burn marks on the wires or boots. If worn wires are the cause, this set replaces them.

The listed application uses one set. Country of origin: United States.
