Have you pulled your dash apart yet? Might want to make sure you don't have anything "stashed" there that's blocking your air flow.



I wish I had something immediately useful to offer, but unfortunately I'm not super mechanically inclined. I do wonder though, maybe one of the many people promising hood / insert mods would consider doing a fully vented hood? A guy did this to his G35 a few years ago and claimed it lowered the engine bay temp by 100+ degrees!
