So the stock intake has an intake air tube drawing air from the front grill, whereas the cone style is drawing air from the engine bay. Given that it's straight from the engine bay the intake air temperatures will be higher because of the heat from the engine warming up the air surrounding the intake and etc.

^^ thanks! Saved me some typing...
What we know about these engines is they dump timing (i.e. pull back ignition advance) pretty quickly as the ambient air temp and or heat soak increases which directly relates to reduced power output as the ECU is all about protecting the engine from spark knock.
