1. Answers.com is hardly a technical data source, and should not be treated as anything close to such.

2. You still haven't proven that a warmer engine is necessarily going to "live a shorter life" compared to a cooler one. The problem with this statement is that it assumes that everyone already agrees that a warm engine is actually a hot engine, which it is not.

A cold air intake doesn't necessarily increase horsepower. In some cases, the same gains could be made (at WOT, obviously) by simply removing the air filter and air box.

Where exactly does a CAI make gains at less than WOT? Show me that? If colder air is really making more HP in the capacity of the CAI, then even at part throttle, there should be enough excess air density to make more power compared to the same throttle with OEM intake.

Obviously, an engine has a limit to the amount of heat it can stand before it starts to grenade, even over a long period of time. Engines run most efficiently when they're not wasting heat, which tells one that the excess heat created either needs to be utilized, or not created in the first place. Since combustion creates heat, and ICE's aren't truly all that efficient, having a warmer engine means that less energy is sent through the engine as heat, and more as power. There is a reason that cold engines don't run well.

Saying that anything beyond "warmed up" is less then beneficial is just a cop-out statement, which shows that you're probably regurgitating information from someone else's mouth. You can't confirm that "warmed up" is an actual operating temperature, nor can you confirm that if "warmed up" were a concrete state in terms of temperature, that it would be the most efficient state for all applicable scenarios. Without being able to prove any of that, this statement needs no further review, as in the looking glass of scientific scrutiny, it holds no weight whatsoever.

If cooler engine parts mean a longer life - again, a generalized statment - why does the engine need to be warmed up? Now you're contradicting yourself...

I'm not even going to start on the non-scientific (or even considerably credible) nature of the CAI article.

Please, continue this discussion when you can find real evidence and studies to back up what you're saying.
