I dont have them, however im kinda price checking. If you know anything on these, could you let me know? oh by the way I have an extreme flow muffler on my 2001 1.8 and was wondering how easy or difficult the CAI from hotshots is to install. And is there anyway to "beef up" performance throught the ECU for my sentra. All advice helps. Thanks
