I bought it off a guy who sells his homemade VS on lowyat.net. Might have given me slightly better fuel consumption, but could be also be attributed to a slight change in route on my daily commute. Then I changed my VANOS seals and my fuel consumption improved further. Mine's a manual so I can't comment on the improvement in automatic gearshifts. Other effects aren't apparent to me.
Good info bro... this what i hope to hear & share from the member... hope more member share the brand and the review after install the VS here...

im my view these after market VS things are like the other things that you put in the petrol tank to 'align molecules' for increased MPG etc, just a gimmick----- if your alternator is in good nick, and your earths are clean and tight you will get all the benefits as described for the after market VS !--------- apart from 'increasing torque' that is !!
Is it near KFC there ? I have changed e36 alternator which very near the KFC Sea Park. After installed the recond alternator around 1 week. I found out that the alternator not enough charge. The boss of the shop refused to change it and keeps on said the alternator is working fine. After 1 month the alternator is dead then i asked him to change but he dosent wants to change it.
