 I would find the best price on new ones as the nozzle wears.

 Doug Fir likes these Seimans.
 They will also fit.

Paul,

I looked on the web site for siemans that fits Mazda RX8 but they do not
seem to manufacture injectors for the Mazda.Beside is there anything
wrong with the Denso injectors.I always thought that the Japanese are
better than the Germans when it comes to automotive stuff.One more thing
the Denso have 2 different injectors one type for automatic transmission
and the other is for manual transmission.If you think that the Denso are
good which type shall I order the manual trans ones or the automatic
trans ones.Thanks.

Michael

Injectors are injectors. They are all pretty much the same if
they physically fit and they flow about the same.
Tracy's system can compensate for different flow rates.
One can also adjust the pressure regulator to adjust
the flow.

Order the manual ones.
