$4,000,000 - FOUR MILLION dollars for the auto company to add a $4 widget per car, if they sell a million cars. And since businesses are in the habit of trying to cut cost, while trying to earn a buck, any and all extra 'widgets" that are really not needed are ixnayed.
Or you spend the $4, raise the price of the vehicle $10 and nobody will notice the $10 on a $30-40k vehicle. Few would dismiss a car over $10.
If it did the things claimed (HP gains, MPG gains, etc) then it would be a steal for manufacturers as it would be a cheap boost to CAFE...
You may even reduce warranty costs if it actually did something. The fact that a manufacturer of a can (supposedly the best) who owned a speed shop could not provide pictures of clean valves or before/after dyno #'s was all the data I needed to see. They are useless for stock applications. He also tried to say MPG would go down due to the valve deposits. Unfortunately for him I have records of nearly ever fill up for well over 100k miles in 1 and 30k in the other and MPG is roughly the same over all those miles.
