It is a very, very (very) old myth that "short ram" intakes suck in lots and lots of hot air and there for make less power than long tubes that draw in cooler air.



I've been around tuning, and tuned in the past a variety of platforms, done real-time data logging with multiple tuning platforms and different types of cars. The ambient intake temperatures when a car is moving with a short vs. long tube is almost always neglible.



The difference between the K&N Typhoon setup and Stillen long tubes will come from intake air velocity, 10x over the difference in the filter placement.
