Hey all!

I just installed my K&N CAI this afternoon. Everything went pretty smoothly during the install (I actually found that the blow off valve was harder to install due to the infamous 3rd bolt). I just went out driving to test it out, and found that whenever I let off the gas, I heard a noise similar to a "horse laugh" come from the filter...is that normal???

I checked everything under the hood before and after the drive, and all the clamps are down tight...doesn't seem to be any leaks anywhere...

 

Yep normal
