[Miata] 2003 Miata Spark Plugs

[mark moore]

With the change in 01 they don't go through wires in the same way. 
That said I seem to be the exception in that I've had a set of RB 
Ultras fail along with the OEM set. I now have NGKs in there along 
with a spare set here for the inevitable day. I'd wait for them to 
fail as most owners appear to get a long life out of the OEM set. I 
also use the everyday NGK plugs with great success, no pricey 
platinums.
