Why is Cold Air Intake So Loud on S/V40?

9 posts in this topic

So I put my cold air intake back on a few weeks ago. I have the Eurosport Tuning one. I have helped various friends install CAI's on all types of cars/trucks (turbo, non-turbo) and none of them come close to being as loud as the intake on my 2004 V40. Here is a video for reference https://www.youtube.com/watch?v=7hZ0VGp6uXM

In the video I am barely touching the pedal, all the windows are shut, and I am going around 40-45mph. Everyone who hears my car from the outside or rides in it is blown away by the noise. I had my brother drive by me and it is hysterical. 

Is there any reason it is so loud compared to other vehicles with similar layouts?

They're definitely loud.  I had a guy in the neighborhood that was walking his dog yell "SLOW DOWN"  when i was pulling away from a stop sign,  was maybe going 15mph.

Haha classic! The only downside in my opinion is that I seem to get 5-10% less MPG's with CAI installed. I'm assuming its because the air fuel ratio gets manipulated. Need a tune, if only it was easier/cheaper with these cars!
