i don't know that i buy that. the air coming through the radiator gets deflected by the engine around the sides and up, which happens to be right where the vents were conveinetly placed the hot air is rising directly at the vents. anything in the way is seriously going to disturb the airflow thus reducing cooling efficency, i suspect.HondaH8er said:I spaced mine. That way, the help keep stuff from getting into the engine bay too easily, but the air can still get out pretty easily.
Lavery said:I have my vent guards off, but not my scoop guard. I read in more than one place that you should make sure and waterproof your plugwires before you do this. I have been to lazy to do this. Chances are it wouldn't hurt even if water got onto them, but you never know.
Boy said:4 yrs vent and scoop-blocker free. I've lived in OH, NY, MISS (gulf coast), TX with no problems. The car has 95000 mi and only one blown MAF (different intake setup). If you have a short ram (cone filter) intake you should be fine in all weather b/c the intake cannot suck enough water to damage your engine (unless you do actually try to scoobadive). With a fender placed CAI (especially cobb or ganzflow, etc) the hood vent wont be your problem, it'll be submerging the end of the filter tube and having no way for the water to escape.
The ONLY side effects to opening the vents/scoop is
1. Dirty Engine bay
2. Negligibly increased drag
