Allways looking for a relatively cost affective way to increase hp. Has any one had any experience with a CAI system for the 07 3.3 Santa Fe? Are there any good aftermarket systems available, or has anyone made their own? Also, I was reading a thread on another forum about someone who plugged the opening for the resonator box with good results. It was an older model, and only had one. I notice that the 3.3 has two. Any thoughts or comments?
