its back from the dealer, we determined that its just engine heat escaping through the seat belt area, as PaPaCraig said, the valve cover is very close to the plastic, so its a design thing, Im either going make a heat shield for the area, Or go with another suggestion my buddy came up with, which is, make a dummy snorkel with a blower motor to blow the hot air downward, and away from the area, I think it will be the easier way to combat the problem. Not to mention look cooler with dual snorkels rather than a single. Service guy said they would forward the problem to Honda, I wouldnt be shocked to see a heat sheild added on the 2016 models.
