Someone help
 

cut pipe down, ran a vaccum hose off that with a rubber boot down towards a velocity tunnel then installed intake to vaccum setup is dialed noticable difference in the cars acceleration and speed overall more effecient.

pix please, what intake, what year, make, model civic

+1 on all of that

The air sensor is really important. There should be a bung with a rubber grommet on the intake pipe for the sensor to go in.
