MKIV TDi engine performance upgrades...

[Kyle!]

to be honest i am not entirely sure about cold/warm air, but the pipe has made a difference as it allows the turbo to kick in quiker so feels more responsive plus the induction kit makes the car sound a little less of a diesel canel boat sound  a photo update will be made soon

really you think so??? i took mine off coz it sounded ridiculously loud... a lovely turbo noise tho...

depends on the quality of the induction kit and the steel pipe, mine is custom fitted so sounds lovely
