Which Air Intake Position is best?....
bacillus:
Not seen anything myself but I'm being more swayed by the ITG offering.
If you're wondering why, it's because of the ITG's cross section area at the maf (almost identical with stock) and apparently better fuel trims or should I say, closer to stock, compared with the twintertake. Mind you, the actual number of users was very small in both cases.

you cant ignore the fact that they have got rid of the integrated engine cover/airbox with the new TSI for an induction pipe running from the ram scoop to the turbo. surely that shows the std airbox was restictive, but the scoop in the grill is ok

You will not find a higher pressure zone of incoming air outside of the engine bay other than the leading edge of the hood right where it meets the grille. This means the OEM scoop location is by far the best spot. If anyone can produce wind tunnel data that relays differently I am all ears but VAG's own wind tunnel testing proves this quite handily.

That isn't 100% correct. On the Golf Mk5, the area of the highest pressure zone is the central grille below the front number plate (license plate :wink:). However, that isn't exactly the best place for the engine air intake, as it would be highly likely to hoover up water in heavy rain, going through a puddle, or crossing a ford. So the best compromise between a high pressure air supply, but minimum risk of water ingestion is where the current OEM inlet is - although to perfect it further, they could feed it through the front VW badge, in a similar vein to the McLaren Mercedes SLR.

....Exactly as Andy at ITG told me.
