Ok so about a month ago I got a new car, a ST202 3S-GE its brilliant just not thaaat fast so im going to install a cold air filter

All i want to know is how to and how much

Take out all original piping and boxes, replace with cone filter, build a case around the filter to prevent heat from the engine reaching it, make sure you have a good supply of fresh air towards the filter, be happy with the hardly noticeble 2-5 bhp if you're lucky.

Is this thing also considered to be a CAI, or is it perhaps just an enclosed SRI? I always thought that CAI is when you extend the intake piping directly into the fender or bumper. Do you have any cost/performance/sound insight on the two options?

You won't really get 2-5hp, you might get 1hp with a bunch of sound...
I have a "short ram intake" or SRI. It just sits in the engine bay.
Cold air intakes, CAI's, usually get mounted in the bumper or fender in a spot where there is good airflow.
It really doesn't do much on an N/A engine, but with a turbocharged engine it does make a bit of a difference.
