Never seen this before: Berk Z-Tube?

Isn't aluminum a great conductor of heat? Hmmm, and if we use it for an intake tube, would it not transmit the engine bay heat to the intake air-flow? And isn't that (in part) what we call heat soak? And isn't heat soak bad for performance? Just wondering...
Looks pretty though if you don't care that it's sapping as much performance as a short-ram. A heat shielded stock z-tube would be best performance-wise.

uhhh, no. It removes the resonator and makes the intake a little louder. Other than that, it looks better. That's about all it does. No HP increase....or marginal/unrepeatable at best.

On a 350Z it's just a dress up mod. On G35's they have a tiny OEM intake tube. The Z-tubes have been dyno'ed by a handful of people on the G35 forum. They all had a modest 4-5hp bump.

No, because the air travels through the intake tube so fast that the intake pipe being hot would have practically no effect.
Heat soak is commonly discussed in terms of having an open ended filter without heat shields and etc around the filter. The reason why some people are anti heat soak, is the theory is that because the engine bay is so hot, with an intake filter thats not shielding out any of that heat(hense heat shields) under acceleration the car is only sucking in hot air through the filter. However, there have been tests documented with heat sensors and computers in an engine bay to test the true effect of heat soak. The conclusion was that because there is so much air flow in an engine bay(just from your car moving) that heat soak really doesn't have an effect regardless of open filter, or filter with heat shields.
hope this made sense.
