Upgrade Air Filter

[gribbo91]

Does anybody know if there is a upgrade air filter already on the market for the new 2.0 TDi 177?

Been searching and no definite answer

If you mean an expensive piece of card covered in "special" oil I wouldn't bother

stick with a standard filter and save all the grief and no extra power that comes with all the others.

This ones for economy, as its for my dads C7. ive got one in my C6 and with the remap it helps my economy

In most cases (from what I've read) a performance air filter will do zilch for a derv and could (in some cases) make things worse.

go on then, what have you done to prove it helps and by how much ?

I found that by just changing my old clogged OEM filter for a new cheaper aftermarket one made a difference (SoTPD of course!) am betting had I had it dyno'd before and after the change would have seen a few BHP.

So bought 4 x filters (£20 in total) and will just change every year....so more air=more power

On a diesel more air without adjusting the engine settings, fueling etc won't make a difference however cheap aftermarket ones will allow more dust etc into the system which is only good if you sell turbos

a high flow filter is useful if you are tuning an engine to the absolute max, but then most cotton gauze filters in tests don't actually flow any more air than a paper filter.

so if you want figures on MPG improvements here goes

March 2013; 35.3 MPG (Stock Map and Stock Filter)
April 2013; 35.3 MPG (Had Remap done halfway through month and new k&n air filter)
May 2013; 40.3 MPG
So far this month 46.3 MPG

Cant argue with that
