Warm up

[nydartsrt]

I let mine run for a bit before taking off, especially if its really cold outside such as this morning.

Hmm, so why do you need a cold air intake for again? Because of the sound only?

Cold air is good for a warm engine because denser air equals greater combustion....a cold engine is not good under any circumstance

[mikew36]

And yes the sound also kicks tail :P

That is why there is and inter-cooler. The turbo heats up the air it receives when it accelerates and compresses it. An efficient inter cooler and charge pipes are the answer to cold dense O2 rich air entering for combustion.
Besides that more O2 for burning means more fuel required, so less mpg.

I don't disagree with the intercooler and charge pipe comment but the intake also helps a fair amount. But more air does not necessarily mean more fuel. People are experiencing better fuel mileage not less mpg with more air. More air creates a leaner condition (more air then fuel entering the engine)

Always let my 1.4 warm up it was -40*C with windchill. Last weekend here like any engine warming up a bit will always make engine last a lot longer. (Take area of where u live in account also). Just start and hammer throttle makes me cringe. Seen a few friends mangle engines in past. Being winter time. Todd

I said O2 rich air. At altitude the O2 content of the air is less than at sea level. So, the people at higher altitudes would probably see a benefit, those closer to sea level will see, more than likely, a decrease in mpg. That is why there is an O2 sensor involved as an input for performance and efficiency.

Always, even if outside 100F, I owned 3 different cars and I always did it and still doing it.

Most engines warm up best by being driven lightly. However, it's never a good idea to drive your car right away upon cold start in any weather but especially when it's cold outside. Machined tolerances within today's engine blocks/pistons/valves, etc are very tight and are designed to operate best at an optimum engine temperature. As such, there are sometimes slight material interferences that go away as the block warms. These "interferences" aren't "mission disabling" in any sense to use automotive design jargon.

You would be shocked at what happens inside your engine when it is started during cold weather and the thermodynamics associated with a cold start.

I warm my Dart up every morning for 10-15 mins before I leave for work. Depending on how cold it is....
