Fits mx5 '99
Works like a charm, easy install. It's authentic NGK and so far works great on my NB miata. Will update if there's anything but I don't have any doubts of the product.

Counterfeit, did not fit my 1993 Miata
NOT AUTHENTIC NGK. DO NOT FIT MY MIATA AS LISTED. MISSED RETURN WINDOW SO NOW IM STUCK WITH EM.

Perfect fit for a ‘92 Mazda Miata
Picked up an NA Miata that needed basic maintenance all around, and couldn’t find new spark wires anywhere local to me, these shipped fast and fit perfect, I suspect they will be fine for any NA6 Miata
