I've run K&N filters on all my cars without issue. The guys at Tunit in the UK reckon that running a K&N panel filter on their remapped GT TDI has improved airflow by around 30%, and provided an appreciable performance improvement. I think the key to avoiding MAF sensor problems is simply not to over oil the filter.

Welcome to the new look VWWatercooled
After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.
Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

Ahh the old K&N debate....
I have a panel in my TDI, and whilst I ran the stock one on the dyno, when I swap it I don't really notice anything. I just like the fact that you CAN service it, and in that way pretty much keep it at optimum all the time. Again in both Modshacks and my humble opinion, the problem is the lid elbow, not the filter.
I too found a bit of info on the oil killing MAF's, but they were speaking around 50 to 80 thou MILES, and as a new MAF costs a whopping $60 US, it's no big deal really.
All the same it's WHY I have a nice Apexi dry pod on it's way, and it will go into a shielded pod setup like this. Mik's setup is great for heat shielding, certainly NOT an open pod style, and the only possible flaw I can see it that the front of the beautiful Modshack tube would ideally be sealed so that air can ONLY be drawn through the front entrance, and not around the front edges of the tube.
Mik's words sum it up...he FELT a difference. After all, isn't THAT the main goal?2014 Skoda Yeti TDI Outdoor 4x4 | Audi Q3 CFGC repower | Darkside tune and Race Cams | Darkside dump pDPF | Wagner Comp IC | Snow Water Meth | Bilstein B6 H&R springs | Rays Homura 2x7 18 x 8" 255 Potenza Sports | Golf R subframe | Superpro sways and bushings | 034 engine mounts | MK6 GTI brakes |Comment

howdy all. Figured i'd resurrect this thread with a few comments. I've recently taken my Modshack VTDA off my TDI after about 20K kms, and have also done about 2 full tanks of fuel after having it off.
I have clearly noticed a quieter engine (remember we like a little bit of intake nastiness, its why we go pod filters
) but the lag and delay is back. There is also a distinct lack of low and mid pulling power because of the lag.
Lastly, I've noticed i am getting 100kms LESS out of each tank now, with absolutely similar driving to my previous 20K kms (mostly 160Kms per day of highway at least) so the economy has gotten worse. obviously, its still awesome dieselness compared to petrol though, but still.
Conclusion - The VTDA on the TDI was a great mod and helped fill a torque hole and increased fuel econ markedly.MY02 Bora V6 4Mo|Matte Black plastidip|VTDA|R32 Exhaust|R32 dampers and springs|TT pedals|R32 steering wheel|17" 8L S3 rims|R32 sways|Blue Haldex|EBC redsComment

Who sells them? I assume they come with a pod filter in them?Comment

Ian at Rennenhaus - you need the model to suit MKV R32.Comment
