Hey guys, I am making the attempt to build my own cold air intake on my 1998 Grand Prix GTP, but I have some questions in which I am hoping can be answered:
1) I've tried my research, and I may just be missing something, but would I need a 4" air intake pipe? Or a 3"? This decifers the size of filter I need to buy as well.
2) Has anyone else made this attempt, and built a properly function housing for one? If so, could I get the dimensions?
3) Do you have any tips or suggestions on me doing this?
If I could get some answers and help that would be great! Thank you very much!
