Racing plug runs colder, not good for a daily drive. There is no performance difference. Dif is that racing plug may minimize detonation under racing conditions because it's colder and it will most likely foul if used for regular dd.

|
I guess I'd go with the NGK bcause of price.

The Mazda NGK are Iridium. The ones I put in on Saturday had the IR on them.

Yes the OEM-NGK are your best bet. Have the coils and wires been replaced yet? Let us see the plugs when you get them out.
|
nop, the coils and wire are OEM

I have never seen anyone NOT recommend the NGK OEM plugs for a rotary engine.
Stay with the NGK OEM's. |
