<-----You can see where I installed GenRight vents on my hood. They work well to reduce underhood temps. Driven in all seasons and weather conditions with no negative effects.
As luck would have it, I have a brand-new, never installed GenRight TJ hood vent for sale for $30 AND I live in the area south of O-town, so we should chat. 801-390-9 zero 1 ate.
