Colder air is denser and the ecu will increase fuel to keep a proper ratio.
Carbs can't do that. FI vehicles almost never have heat risers like a carb
does because they arn't as suceptable to icing. That's where having an intake
under the hood in cold weather is better than sucking in outside air. A friend
of mine uses a hot air system from an old pickup and plumbed the existing
air box with it.

Yeah, I've been thinking about something like that. Gives better gas
mileage and makes it more driveable.

Back in the 60's that used to be an every day occurrence with Rayon (I
think) tires. If you let the vehicle sit for a day or two, all 4 tires would
have flat spots that took a few miles to "round out."
