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
