I have been using the Splitfire plugs in my Miata for about a year now
(installed them last Spring).

I can't testify as to whether they have really increased my gas mileage or
power, but they certainly haven't caused me any problems either.  They are
a little expensive though...

Let me re-iterate some warnings from an earlier date that Bosch Platinum
plugs may not survive the Miata's funky one-coil-per-two-cylinders
high-voltage wiring scheme since they may not tolerate sustained reversed
polarity.  If the ignition system switches polarity every spark, they
should be OK.  I dunno if it does this though - it is unlikely.
