K&N 57i

[buckshot]

Have any of you good people fitted a K&N 57i cold air feed filter to a 2.0 TDI?
Just wondered if there's any performance gain over a K&N drop in replacement unit.
I fitted a 57i to a 3.0 V6 Laguna previously and it upped throttle response quite a bit, to say nothing of the induction roar (nice) when the loud pedal was introduced to the carpet!
ATB.

You won't feel any difference or have any gains using any aftermarket air filters on a diesel I'm affraid just noise benefits

Sorry I beg to differ.i had one on my tdi,and it made 194 bhp and 410 lb ft torque which was 10bhp over what I should have had! You could hear the turbo spooling too which may be a good/bad thing (I liked it!)
Major downside was the car smoked a lot more!

My mate who purchased the car off me didn't like it so took it off and went standard,and he also found a noticeable power loss,but less smoke! So its a trade off!

Sorry I'm sure diesels need more fuel for more performance not air like petrol engines?!
