air mods???
 

On my 01 cummins 24 valve, I have just the stock air box and filter. Is there any way to mod this besides buying a whole new air intake? thanks:rocking:

use a piece of 4 inch exhuast pipe and a cone filter or the aka bhaf and make a homemade heat shield

get a stock size k&n filter, i got one it seems to make a diff.:tu:

take the box out and put a performance filter in its place..

X2 i did that it helps alot and turbo wistle is awsome :tu:

I did mine for only about $45 too
