sharing some info..... :D ..........

For everyone that swears that a CAI is not worth while on our cars and that the stock airbox can supply enough air needed, I did a test. I have the EVO CAI and I wanted to try out my modfied airbox. I shaved the top of the box, cleared the bottom of it, added a 3.5" expensive hose to the box from the front of the car, and added an ITG. Well guess what, it pounded the EVO into the ground like a fence stake. No more EVO for me. I am only going to show the airmass but the hp is higher as well, by 3 - 5 hp over the EVO from a block 120.

Stock Box w/ stock filter, smoothed inners = 172 g/s
Stock Box w/ stock filter, smoothed inners, ram hose = 177 g/s
EVO CAI = 178 g/s
Stock Box w/ ITG, smoothed inners, ram hose = 184 g/s

Stock Box Top

Smoothed Stock Box, used dremel, sand paper, and love

Hose with to much space

Hose with filled in edges using insulation tape, the wire was removed so entrance was smoother later.
