I tried using the search tool but couldn't really find anything too helpful. I am looking for a replacement filter for my TDI that will give an ok power increase. Do K&N etc make a TDI-specific one? Looking to spend around $100, not $900 on some carbon ram-air intake system....just the filter.

You're wasting your money, VW would fit a better one if would make a noticeable difference, all you may do it get a little more noise at the risk of letting more rubbish through the filter.Originally posted by nick_sixx View Post

To answer your question, yes K&N and most of the aftermarket filters make a MKV Golf/ Jetta one, and if you do want one, they show up on e-bay for about $70, don't go paying the standard $120 or so!
I noticed no difference though, and even my full Modshack Pod difference was minimal, but yeah, I'd still get one.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

The standard filter breathes very well on the TDI.
Avoid oiled filters, consensus (and indepth analysis) from tdiclub.com indicates that they are MAF-killers.
Other lessons from the fanatics on tdiclub:
- avoid changing the air filter more than required (e.g. more than specified unless extreme conditions) as this can allow dirt into the engine.
- same goes for checking the filter condition. every time you open the air box you let crap in.Comment

If you do go for a pod, buy a CALIBRE brand pod from Supercheap auto. It is a urethane filter (no oil) that outflowed everything else and added 2.5kw on a test car in Zoom where nobody else got above a 2kw gain. This was tested by putting all the various pods on the end of the same tube placed outside the engine bay in cool air. Same car, same day, same dyno. In that test the brand was called DRIFT. But now they are Calibre.
It is also important to note that the 2.5KW gain was ABOVE having no air filter at all and just letting the 3 inch pipe breathe unfiltered.
Great result and they only cost about $35
Has a bellmouth internal inlet and the vanes are spun to create more of a vortex.Last edited by POLARBEAR666; 11-03-2009, 04:46 PM.*Disclaimer - Don't rely on me, seek your own professional advice. Audi R8 E-tron. 230kw 4500nm! (not a typo).

I do it just so that over the next couple of services I don't pay $15-$30 for some crap paper filter which they probably don't even install and just charge me for.Originally posted by Logzy View Post*Disclaimer - Don't rely on me, seek your own professional advice.

The purpose of the air filter is to filtrate air.
If you replacing the OEM air filter than you have to make sure that it filtrate air as well as OEM one. I found out that some aftermarket filters offer less filtration and in the case of panel filters they don't seal well against the air filter box and sometimes even impossible to be fitted correctly.
As the engine wears out very quickly if it sucks in unfiltered air with dust and sand you will actually end up with less power that you would keep proven and tested OEM filters.Performance Tunes from $850Wrecking RS OCTAVIA 2 LinkComment

Let me guess, you'd vote for keeping it standard?

I have nothing against not OEM filters as long as the filtration is not affected.Originally posted by cogdoc View PostLet me guess, you'd vote for keeping it standard?
Our Forester has Unifilter it the place of OEM air filter from 12,000km (it filtrates better than OEM one and the fuel economy had improved). VW cars get OEM filters - no reason to muck around - good fuel economy and good power.
Yes, keep the TDI standard.
P.S. I don't mean you. How is your 12V fan instalation in the engine bay going? I hope you will post the pictures with other details (what fan etc.)
