User Experiences

“These are the Miata wires you are looking for… Standard issue Miata Plug wires, fit and work well. Unless you are running some serious boost or something else crazy, these are the wires you need. Don’t know when your’s were last changed? Just buy a set and replace them. The ones that came on my pre-loved 1990 looked good form the outside, but the #3 plug top/wire was separated from the conductor (Not Good). New set of NGK plugs and wires, she runs much, much better!”
