Intake: Polished or Powdercoated?

[Silver Ecstasy]

When referencing to heatsoak, or what's worse at heatsoak, which do you prefer? I hear the Cobb silicone tube heatsoaks, but I honestly can't remember reading which one heatsoaks worse.

I ask because AEM offers an option powdercoated silver or polished aluminum. For performance reasons, I ask.

Bare or polished aluminum passes heat better than just about anything. Getting it powdercoated or ceramic coated would be the best option to keep the heat from transfering to the air inside the tube. If you really want to get anal, you could get the polished one and then have the tubes ceramic coated inside and out, but we're talking $$$$$$$$$.
