Id just like to say that IMHO the Ecotek Valve really works - BUT it is flawed. Ive had one on my car for 4 months and found that my car runs much more smoothly at low revs - no more "just passed test" jerkiness, and running costs are down too - instead of visiting the petrol station every week i now only have to go about every 10 days or so. But there is a bad side, the ecoteks induction noise on rundown can set can alarms off and every time you slow down at traffic lights everyone turns round to see where this awful noise is coming from - well at least your car turns heads i suppose!
Moo ha ha...moo ha ha...moo ha ha...
