Would there be much of a difference between getting the airbox with that additional hose vs. just getting the k&n filter? The air is already sucked in from the front grill which I would think gives a lot of cool air.
I am not an engineer so I don't think I can answer that question completely.
The Mountune air box does not delete the intake from in front of the grill.
It just adds the intake from below.
If you are correct and the K&N filter is all you need, then why have ALL other CAIs added more holes?
Maybe you are correct and all the extra holes are just for the noise.
Maybe we have just been lied to all these years and these intakes don't really do anything except for the noise.
I do know that colder air is a good thing and more of it is better.
I chose the Mountune because it does draw more air from a cooler source.
You will have to make your own choice.
