Spark plug Autolite or OEM Mazda
We both run Autolite Platinum and they fired up no matter how cold it is on the first try.
Pros: fires up easily, good in cold
Vehicle:
Volkswagen Corrado
don't feel like changing them every oil change like I did with the autolites that constantly misfired...
Cons: constantly misfired, frequent changes
i'm running autolites right now and i'm not too impressed with them
Cons: not too impressed
I tried the 3923's and my car ran like arse - rough idle etc.
Cons: rough idle
