Default 00+ gutted airbox

I wanted to do some chopping on my stock airbox after seeing it in another thread. Here'* what I did. Tools needed- dremel with cut-off disks and a thin hand saw (jigsaw blade in a vise grip worked great for the plastic ribs that the dremel can't reach).


Here are some before pics of one half



The other half


After of the first half



Second half


She sounds a bit better, with more of a 'woosh' when gunning it. However, this sound isn't quite as pronounced as those I've heard with cold air intakes and probably FWI (as I've never heard one). Not bad for a half hour and $0.

The surgery looks successful.

The SC engines will produce a much sweeter sound amplifying the whine.

In a NA engine it will produce a lower tone and sound of air rushing in. You might even see 1 or 2 mpg better on the highway.

You will notice a better power gain from a cone filter, as long as it is isolated from the 130 F engine bay heat.

Nice, I did not go as far as you did when I did mine, just around the rectangle and I left the ridge that goes over the PCM. Although looking at that gave me and idea, maybe cut back the tube that goes to the rest of the intake a bit short and maybe put a cone filter on there? Wonder if it is a possibility?
