Just installed on a 2020 TRDP, no issues with fitment or mounting points. Did notice the whistling immediately anywhere from ~1200-2200 RPM while accelerating lightly at maybe 1/8-1/4 throttle. Sealed all holes and it seemed to whistle a little less, put in the stock paper filter and the whistling is gone!
Figured I might as well have the CAI to go along with the TRD exhaust...
