Waste of Money best in my review

These spark plug wires failed to perform as advertised. The connection was poor and the engine misfired. I expected better quality from an automotive product.

Pros
  • None
Cons
  • Poor quality, caused engine misfire.

Fits Mazda Miata '99

Excellent fit for 1999 Mazda Miata! Hermetically sealed and contains dielectric grease. Good alternative to NGK blue wires. Update 16/07/2020 Bought it a second time now for a 1991 Miata and it worked just as well as it did on my last Miata. Good alternative to NGK. Original Denso part.

Pros
  • Ignition Parts
Cons
  • Hardware Sad

Perfect fit - highly recommended!

Used NGK ZE21 wires but decided to go down this route after noticing some comments about dust boot/gasket failure. These Denso cables were perfect, can't say more - I had a bad cable and they were old on a 1999 Miata 10AE and it solved the problem and looks/fits perfect.

Pros
  • Wires
Cons
  • Minor issues
