What did you use to cut a hole in the firewall?

3.5 inch hole saw and a careful hand

What kind of differences have you noticed this making with your truck?

A few more mpg's alittle more lowend grunt and a little sound diffrence its all alittle bit of change but ends up being pretty noticable

Does it suck in water when raining??

I've been wanting to do this exact same thing, thanks for the pictures, looks like a clean setup.

Does it suck in water when raining??

To be honest I was very worried about that the hole I cut was about 2 to 2.5 inches from the bottom with the tube slighly angled upwards so most likely the bottom of the tube opening is about 3 to 3.5 inches from bottom.

I've driven in several downpours and let it sit overnight in rain and snow I've never had a hint of water in the air cleaner so id say I'm safe

And if you are worried about water in there, add a slash cut or turn down. I was looking at doing something like this but am going to probably go with a factory 6.0 inlet and add smooth pipe to get rid of the bellows.

On a different note, can you post a pic of your return line routing? It looks like you have it going directly to the cap on the #2 cyl.

How did you attach the tube to the firewall?
