one that works! Track dog racing sell's the NGK V-Power™ Spark Plugs which i heard are the best for Miata's.
Whats the best spark plug for a 1990 NA 1.6?

+1 on standard NGK's, but don't forget to get new wires. NGK Blues... make more difference than ANY plug, even if yours look ok.

Sweet or as I just learned today you can get them at O'Reilly's for $2.49 ea. p/n BKR5E-11
Got 8 today for my gaggle of Miatas.![]()
I read on all the forums that any form of the NGK's are great for miatas with their blue wires, I'll be doing a tune up on my Na soon with new NGK's/Wires
The V power NGKs are $2.09 at Pep Boys, $2.29 at Autozone. Just bought the BRK5E-11s and swapped out plugs. I thought the early NAs to the -12s?

Pep Boys sucks no way I'd step foot in a Pep Boys (YMMV).....
I do like the Vato-Zone but the O'Reilly's is just down the street.
I'm pretty sure all NA & NB Miata's use the 11's.
