Air Foil
 

Those who have installed a throttle body air foil, did your intake get louder? When I installed mine, the intake noise doubled. It sucks super loud now. I thought maybe the K@N filter was cracked, but it's in good shape. I checked the whole intake system for leaks and none were found.
I'm not really complaining it's loud, it just seems weird that a simple air foil will create such an increase in noise. So did this happen to anyone else?

mine did back on my bolt on lt1. i dont know that it doubled per say, but the airflow definately got louder.

Mine did a little.

mine got slightly louder.

Mine didn't get louder.

Couldn't hear mine over the open exhaust.

never noticed a difference

I guess some of you did, and others not. It's really loud outside the car and I can hear it inside if the door is open or window down. It really did double in sound. I'm probably going to take it back off just to see if it goes back. I don't care if it's loud, I'm just making sure it's not a leak somewhere.
