K & N CAI Need help

So i put in a K & N cai over weekend, everything runs good. But when i step on accelerator i hear a whistle sound for like 2 seconds its not terribly loud but its there. Is this normal with cai or did i do something wrong?

Some CAI are known to have a little bit of a whistle. I would double check and make sure all hoses are fully seated and tight and that nothing is loose. Sometimes, more noise is in the nature of modifying cars

The whistle you hear is normal for the CAI. Trust me. It's no problem

If you get a bigger throttle body like I have, there is no whistle. Sound good though eh?

+ 1. A slight whistle is 100% normal. However, a whistle, followed by toe tapping, knee patting, head bobbing, and a good old fashioned square dance would be abnormal.

That's hilarious. Lmfao.
I liked the whistle when I had it, but now no whistle with the 76mm throttle body. Compared to the stock 71mm one.
