Installed Airaid kit for 6.2L. For those considering the full kit (202-111), the install is straight forward. I suggest installing the filter to the box coupler prior to installing the coupler to the box - you cannot get the filter installed if you wait until the end.
Noise has a nice throat when the throttle opens. Noise while cruising isn't noticeable. Cannot comment on whether the supposed +/- 10hp exists since the truck is 5 days old (not near break in) and we're dealing with 420hp to start ?
I was reluctant as many are with the open box concept as I like the sealed tops better, however it seals nicely to the hood and the new hoods seal better to boot. Overall, it's a classic, easy and enjoyable mod - happy so far.
