I recently acquired a 2021 Sequoia TRD Pro and was a bit surprised that it doesn't have the hood insulation under the hood to quiet down on engine noise. Doing some digging around I found that some Tundras do have this (part 53341-0C021). I called the dealer and they don't know if these are interchangeable or at least couldn't confirm it. Has anyone tried to put the Tundra insulation kit for the hood into a Sequoia?
