Lets start with the fact that the SAE correction is on the order of ~1% per 10 degrees of intake temp change. Lets say even 1.5hp per 10 degrees on a Focus. Now remember that this is the temperature of the air. However the pipe will not be able to transfer anywhere near enough heat into the air to make the air at the same temperature as the pipe by the time it passes through the throttle body. Off hand, I would guess a 10 degree difference on the pipe might make a 2 degree difference in the air continuously flowing through it. Which would mean a gain on the order of 0.3hp per 10 degrees. Just how many degrees hotter do you believe the intake tube is than the air entering the filter?

How are you defining heat soak, and why do you believe it to be problematic in these cars?

Just like Driven5 said, the heat it absorbs is negligible to performance. And while you're driving the temperature isn't as high due to the airflow over it. You're worrying over nothing
