It does not suck in a lot of hot air. Unless you're stopped for an extended period of time or using a dyno with a closed hood. Neither of which constitute real world driving.

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 negligible.

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.

What kind of IATs are you seeing with these?

Good info, thanks. That makes me wonder if I should get a different brand of filter though, because these K&N filters are closed on the end facing the ducts, only allowing air to enter along the sides of the filter. This already seems counterintuitive to me, but if intake velocity is that important then this has to be limiting my gains.
