Here's my experience of the Ecotek valve, for what it's worth. I bought one 2 years ago for my Mk4 Vauxhall astra 1.6 16v. It worked very well on that car, attaining a decent 15% to 20% improvement in mpg (both urban and on a run) and it smoothed out the flat spots on acceleration. But when I bought a Mk3 V6 Mondeo last year and fitted it to that, it made no difference whatsoever to the mpg and the engine ran lumpier. I guess it works on some engines and not on others.

These things cost pence to make so, if they were any good at all, the car makers would be fitting them as original equipment!

I read the adverts. Then I looked on ebay. Lots for sale secondhand. If it's that good why sell it? (most looked as if they had been used for under 6 months)..

(and at the prices they fetch secondhand I would buy new.. some contradiction there?)
