Whose kept their oem air intake?
Dan_FR:
Some intakes make that whine on a K03 and some dont. Its a horrid noise. I found the smaller diamater pipework (all one diameter, usually 70mm) to be the worst for it.
It will of course go completely with the standard airbox on as that thing masks all noisesm
r5gtt:
My Neuspeed P-flow doesn't make that noise but screws with my power so off with its head :P and back to good ol old school ugly box :jumping:
Vwgtiking:
I need a little help. I am thinking of putting the std air box back but instead of using the oem air duct from grill to the air box am thinking of using a large piece of silicon pipe from the box to the grill. Just wondering if there is anything out like what the twin take or vwr use that hold the pipes in place in the front grille??
r5gtt:
I really wouldn't other with it mate. too much hassle for nothing imho :smiley:

No

I've already shown you the Forge offering which is the only aftermarket replacement unless you have the means to fabricate your own.

It's all matched together, I am sure the intake length, manifold design, Intake runner etc etc is all optimised for the airbox. I tried a induction kit and it ruined the low down torque and general low speed drive ability.

It's not as simple as that, the standard airbox is designed to be quiet whilst using a cheap to replace paper filter. You can't have a matched airbox with the intake etc. when you have a turbo and several feet of twisting, narrow pipe between them.
The crucial most overlooked part is the MAF sensor reading/scaling. A lot of aftermarket kits, including the RamAir kit, ruin throttle response and low down drivability (and even produce what feels like lag) solely from the MAF reading/scaling. I've learnt this from experience having bought their MAF pipe to try. I took it off within a mile of driving the car and replaced it with another MAF pipe

I'm not convinced it's only the MAF scaling causing drivability issues Seems to be anyone who fits a induction kit reports a loss in low down torque, some just put up with it. Are you saying not a single induction kit has correct MAF scaling ?. I tired a Revo kit back to back with the standard airbox and Revo make a big deal about MAF scaling. That too didn't drive as well as standard airbox.
I agree with you that having the turbo in the way of the inlet flow would mess with things compared to a NA engine. But from reading post after post and my own experience with the Revo kit there seems to be more too it. (Whatever the cause)
