i have a 93l 5spd efi. i want to put a small hood scoop or vent on the side of my hood over the intake filter. i am in utah, and have heard that if the air entering the engine is too cold, it has some kind of negative effect or something like that. is that true? any help is appreciated.

None that I know of. Colder air is denser air, which allows you to add more fuel to make more power.
It's a good thing you don't read the stickies, you might of learned something.

In the winter my car never warms up fully.
It's even worse when I have my ghetto cold air intake piping on there.
Something tells me that neg 40F air hitting the tops of my pistons isn't all that great.www.dantheoilman.com

too much cold air blowing over the engine can make it harder on gas, but intake air, the colder the better 8)Comment

a scoop can cause alot of turbulance which can negatively affect airflow into your intake. a scoop generally only works well if you make an intake box that isolates the air inlet from the rest of the engine bayComment

Many hood scoops are more for looks, than actually picking up moreOriginally posted by InjunDon
air. Almost need a windtunnel to make sure that the scoop isn't under the boundary layer. Best thing is using a cowl pickup close to the windshield.
But read here when even a good scoop starts to add an effect
Now a 1.8L BP spinning at 7k only needs around 200 CFM,
and a stock 1.3 about 100CFM at 5k
There just isn't that much demand for more air, but more Cold Air,
makes sense, as EFI deals with it very well vs a Carb. I just
wouldn't chop the hood for it.Comment

Restricting airflow into the engine bay would be a good idea, especially in winter. Maybe not in summer.
Cooler air to the intake in the warmer months makes a lot of sense, but it's probably not necessary in the winter.
