First off I don't think this filter is giving more power, maybe 2-5hp nothing that I can feel. BUT you do get more intake growl (if you still have your sound tube). I like intake noises, and I think this will compliment my Tomei 60s I will be getting. Also only intake mod you can run for SCCA solo street class. Throttle response is slightly better but that's about it, along with being baller JDM parts!
