i took off the throttle boby spacer and don't see a difference but the sound. oh well, no money out of my pockets.

 

Ya, same thing here. The only thing that I have noticed that the tb spacer does is whistle all the time when i'm driving an **** off my dog. I sure wouldn't pay any money for this thing! Luckly, I got if free when I bought my AirAid CAI. I'm thinking this is about to become a great little profit maker on eBay

 

same here. if i want to here whistle, i can do that myshelf. my companey i work for bought me mine. glad to have it off.
