steering

hey wussup again guys sorry for all these questions ive been asking , but now i got a new question lol, my steering is kinda loose now like turnin wise its not as stiff as it used to be, any ideas??? and also im buying this Cold air box from doctorspeed any1 have any details on it like if it really works???

It could be the rack i had the same kind of problem my steering wheel was turned to the left while dirving straight and it felt like my wheels were going to fall off, took it to GM they said 2000$ to fix the rack and the rack was the most expensive part 1350$ went to Crappy tire they ordered the same rack from NAPA 228$ for it, but get someone to check the steering, first before doing an alignment.
