nope, as long as you have a small screwdriver and maybe a drill (the tiny screw on mine just wouldnt come out). Also get some JB weld (assuming you dont have a real welder) to close up the holes it'll leave behind. Mazda really was into putting random useless crap in these cars.

Its really best to JB Weld it open.

Mazda designed the intake around that valve for fuel economy. If you remove it it will mess with the velocity of the airflow.

yea this would be nice
