Well guys after ly last thread of Mazda making a mistake. I picked up my new CAI from mazda and returned the other one. I took it to my friends house because he had most of the tools for the install.. First of all the resenator was a real :swearin: PITA!! Had to remove the tire, and remove most of the fender lining just to remove the 3 bolts of the resenator. Other then that the install was pretty straight forward. Then I reset the ECU, and took it for a test run. Since the ECU self tunes it self I drove it like i stole it. First impression was 1st gear went by really fast. The pick up was a lot faster compaired to stock. Then the whole sucking noise was really loud also. I thought it was way too loud. After driveing it for a while the sound was getting softer and I was use too it. Other than that there is a fluttering noise from the intake when i slow down. Do any of you guys get that also?
