HOWEVER, the details on the map reiterate like 5 times that you use ONLY THE STOCK AIRBOX. Not saying your motor is going to explode, but your AFRs might be a little screwy and you might throw CELs occasionally. Cobb says that you can use their own SR with the map without issue, though.
Mmm I am just reading about that right now... I'd hate to put it on and have my car run bad......
