As mentioned in my last post, CARB and the EPA "do not endorse" "nor make claim for" any product or service under the guise of additional fuel economy, Period. They simply test a given product (in this case) at the manufacturers expense to confirm the "device/product" does not have detrimental effects upon the factory installed emissions control system.

There are a myriad of products on the market that claim to increase fuel economy, but usually at the expense of tailpipe emissions. (blah-blah-blah)

Answer. The. Question.
