A CAI will not void your warranty if that's what your concerned about.

Thanks BBF for the TSB. That's exactly what I need to show the dealer. My dealership is pretty sneaky when it comes to warranty work.baseballfanz said:The P0455 can be anything from a gas cap not sealing tight to the EVAP canister (stuck switch).
Attached is the full TSB.
