At least on cars where the MAF sensor is located close to the TB the ECU got the info of temperature resp. air dense as is. Regardless if warmer or colder air should not make so much of a difference in general, it cannot be good if the air becomes much hotter on the travel way after the measurement when the MAF sensor is located far away of the TB at the airbox. In this case the engine operates with wrong information about air temp/density.
The other relevant point is the optimal calculated length of the air intake hose to achieve the best resonance in terms of a wanted/calculated power output for a given revband.
Talking turbulences, how is the definition. Does it also mean areas of low air pressure? In 2007 I rented a Caterham for a weekend, when driving faster than 140 km I nearly couldn't breath so much underpressure at my drivers position.
