I don't have a TRX, but I do have a Wrangler with the performance hood that has two heat vents to bleed off heat. A little different concept than an intake, but a hole in the hood nonetheless. I live in central Ohio where we regularly get snow in the winter. Not Buffalo, New York snow, or Montana snow, but decent snow in the winter. Never been an issue with clogging the vents; they bleed off heat when the engine is running. I assume an intake would be similar and give off some heat. Shouldn't be an issue while the engine is running. When parked outside in a snow storm, it's never been a problem. If it's a super heavy, wet snow or you've got some ice/sleet, wouldn't hurt to clear it before you start up the engine. But I've had no issues.
