Just installed air intake on 1.5L!

Just installing a free flowing filter like a K&N in the stock air box often gives better all around performace than a CIA

So free-flowing + colder air is worse? Makes no sense. Remember, the AFE is NOT a CAI (it's not CIA by the way). It's a short ram with an airbox. Let's make sure we are talking about the same thing so it's clear for everyone.

Sorry guys, I will fight misinformation every time I see it.

My position is that once a car is moving, any intake ,stock or otherwise, will be sucking in cooler air.
Does anyone seriously think that a simple plastic shield will prevent the transfer of hot engine air when the car is standing still?

As I previously said, do a dyno test with the stock paper air filter installed, then with the filter removed, then with a CAI/SRI installed and compare the three results. It's interesting that very few do
If some suspect a dyno test that shows that a CIA does not give any benefits due to a faulty test, do we not have to use the same scrutiny (and have the same doubt) for those test that show a slight increase with a CIA, etc?

I'm shure you will agree that anything that helps an engine breath better can help top end performance no mater what kind of intake it is.
Yes, the Yaris it tuned for milage. Howver, do you really believe that that one way they tuned it is to restrict intake air flow?
