im getting ready to put on a ralco undrive pullys,a helix throttle body spacer,new plugs coils and wires,and a programmer. is this a good idea or bad idea? thanks for the help

 

Just go with new plugs, coils, wires, and a Cobb AccessPort. Pulleys and throttle body spacer are a waste of money.

 

Make sure the starter has been updated, as well as the motor mounts.

'04s had weak designs from the factory on both of these fronts and the newer versions are stouter.

The original passenger motor mount on my '04 was completely sheared into two pieces, which led to a rough idle.

 

do they make the cobb for auto

 

Yes, if you can find one. I thought they stopped production?

 

The Cobb AccessPort is still around. Thanks to MazdaManiac!
