This fits my CAI valance box with no problems, but my truck needed some trimming on the plastic part in the fender liner that helps support it so everything fits properly. and attach the lower part of the air intake to the towing hook; the fender seat still sits well where it should and has enough support not to bother me. My truck is a 2008 GMC Sierra 2500HD 6.6 Duramax LMM with 6 speed Allison Crew Cab standard bed (6ft) 4x4 Z71
