The IK looks a little funy, since it is a very flat cone.
When it is on the engine, it looks like a man with a very small hat on.
It is also at the top of the bonnet, where all the hot air is, so it doesn't make it that efficient. Doesn't make much of a difference in noise either.
If you are looking for more power, then redirect the hose that is connected to the manifold (designed to heat up the engine quicker), to a cold air feed somewhere.
If both air intakes are bringing on cold air, then you will get a little more power.
