Since the audio is in Japanese, can anyone say just what exactly this does and what advantages it offers?

T-REV (Teramoto Racing Eco Valve) is a valve system which optimizes the internal pressure by controlling the blow-by gas.
The system creates negative pressure in the crank case and makes the piston and crank shaft movement super smooth.
The significantly reduced air drag in the engine will lead to...

Superior throttle response
Better acceleration feeling
Reduction of Co2

The principle of the product is extensively adapted to the latest racing machines for the maximum performance.
By making the throttle response super smooth, the harsh elements in the engine operation are eliminated, For all driving stages from the street to the race tracks, this special parts derives the natural potentiality from your engine.

The benefits sound, ideal?

I reckon the oil stays "cleaner" longer.

So okay for "race day", but not the daily commute?

Okay, this is cr@p.
Positive crankcase ventilation has been around a long time, I don't need an aftermarket backup system.
But the most obnoxious part of the pitch is the word "potentiality". Like the ever popular "physicality" which has been beaten to death by NBA announcers, it just ain't right. From Dowwntown!!!

Pfft.

Reminds me of a set of valve caps someone was pitching at SEMA years ago. They were “harmonically tuned” to smooch out air turbulence around your wheels to give you better gas mileage. The dude claimed that UPS had just put them on all of their trucks. I seemed half way interested so he gave me a set. I still use ‘em. Who knows...

Gone , just think of all the money you saved in gas.

I know, right?
