well i have a question, I have the blitz FMIC and have a stock bumper, i did only cutting so where the bumper clears to fit the fmic, but as for the black piece in the middle, i didn't bother to cut it... do you think this is a possible loss of air flow since i have the black piece covering? your thoughts please!

 

yea i think it would cause a loss of airflow . . . you should cut out that piece for maximum air flow

 

im interested in seeing pictures of this because im planning on doing the same thing in a couple of months... do you have any pictures?
