This is pretty creative. No one has thought or tried anything like this before. But like you mentioned it might be easier for water to enter the filter. Quick question though. Considering most of us drive at pretty fast speeds won't the force applied to the front of the car mess with your design and kinda flatten the bend of the ramp you did yourself for the air to go to the filter? Idk just a thought. And if it a problem would it be better to weld the desired form? Idk just throwing out ideas. It would be cool to see some numbers if this little mod makes a difference. Either way +1 rep for creativity for you sir!
