if you want more power for free from your civic just take out the lid for the black box that the intake goes to and remove the mesh, the l-bracet, and the 1" disc thats before the throttle body it gives alotta power and deeper tone if used with and intake. PM for pix(too lazy now)

 

This is in the wrong area dude.

 

moved......

 

i dont know about a lot of power but it deffinatly makes a notable change in the intake sound. if you think that mod makes lots of power you should try a mpfi conversion.........its like a 55 shot of nitrous compared to removing the plate and l braket
