How do you know how this is better than Dinan? Just on the sound alone? From other people installing CAI's on their cars, they have shown to have almost 0 performance gains. The only thing that comes from it is the sound.. I guess if the sound was what you're looking for than more power to you, but i would have fixed that torn up bumper and removed those eyelids before i did any other modifications
EDIT: BMW has done these sort of things for the air getting to the engine for a reason, no matter how long or messed up you find it to be..it still works the way it should. hence why putting a cai on it does almost nothing except make some noise and break your wallet when you could put that towards a new bumper.
