"butterfly" in the intake mani?
 

In my intake manifold there is a butterfly (like the think in the carb that open with the gas peddal) Is this normal?

uhh?

what model/engine/etc?

sounds entirely normal to me.

Yeah it is, I was searching with another browser open and shearching paid off for the first time.

u need to be more specific

Shutter valve.

mine was stuck shut, i dont know about yours tho, anyway i just removed it and after i did i could swear i felt a hella difference in the way my car drove.

yeah i think mine is stuck, ill be removing it today. are they hard to remove?

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.

anyone have a picture of a before and after?

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
