The CAI's are identical regardless of the transmission you have, only the engine type makes a difference.
As for suggestions, try
the RPM store, or
Protege Garage. Both sites are well run, have a good selection, and have great customer service. For out and out power I would recommend the CPE w/ Mafci it is proven to add around 20whp. For a cheaper alternative, I would recommend the AEM system, it won't give you near the Hp, but it costs a good bit less.
