I showed this to a friend who worked at K&N for a long time, and he cringed.
He said he's never seen a flowbench or anything other instrument in testing produce better flow results from corrugation vs. smooth internal piping. Which is probably why almost every single intake kit every produced has smooth piping.
He also said there may actually be a small increase in power due to increased velocity due to the tube length (which is the benefit to longer tubes, not temperature) but an ebay short ram would likely net the same power gains.
