I don't really buy into all this oily filter stuff,alot of oil makes it's way into tip pipe from the breather ,if you take of your dv ,you will see the residue.My main concern is that the filter is open to the air in the engine bay,this is what i believe causes alot of failures.The ttda takes a cold feed from outside the car but i can't see how it would be alot better than a stock airbox with a better feed.

Ryan,
I agree with the oily filter situation... I'm not sure there are many PROVEN issues that oil has caused mass MAF failure. I was just offering it up for discussion since so many people DO seem to have a problem with it.
With regard the oil in the breather though... that's downstream of the MAF. Imagine the mess if it were upstream! It's designed so the oil gets dragged back into the engine and burned off but it doesn't always work like that does it!? /ubbthreads/images/graemlins/wink.gif Hence the oil in the TIP. Catch Can is a better system IMO, keeps things nice and clean.
I also agree about the air in the engine bay situation... it's always been a major problem with aftermarket filtration systems, getting a good COLD air feed to the filter itself and then obviously on to the engine. Heatshields are only a part-solution IMO because the filter intake is usually still in the same vicinity as all that heat. Jabba do a nice little 'box' heatshield IIRC, I wonder how well that works... I also wonder how well the insulation that is offered as an option for these TTDA filters works in comparison to one without, and also to the standard airbox.
Do any of you guys have the optional Koolmat heat-proofing?

the whole K&N thing is bullsh*t to be honest. MAF fail for so many different reasons, and oil from filters is not a big reason. Also people use BMC's which are oiled, Green dynatwist .etc with no issues. Ive been running mine for a few months with no issues, and there anre MANY people using the same thing. Regarding the quality i dont think anyone can really pass judgement without ever seeing one in the flesh. I can safely say its the best designed and built intake system i've seen for the 1.8T. I bought mine on the grounds that it offered better filtration... powerwise i wasnt concerned in the slightest!

The reason I mentioned the K&N issue Rich is because, as above, lots of people have issues with them and I think they are widely recognised as having more oil on them out-of-the-box than the general circulation of oiled filters out there... Obviously, if you're cleaning the filter yourself you have absolute control over how much oil goes back on there.
Quality-wise... they do look nicely made. The 'bean can' reference was just me repeating a comment that was made earlier /ubbthreads/images/graemlins/tongue.gif And ok... it was also me stirring the poo in the pot a little bit to see what you guys who'd bought them would say /ubbthreads/images/graemlins/grin.gif
So... (scouse accent) Calm down, calm down!
All in all they seem like a fairly neat and efficient system from all accounts here and I'd actually like to get one myself if it'll fit in the bay... I know it says they are not available for A4's but mine won't be ANY A4 when it's finished hopefully! We'll see /ubbthreads/images/graemlins/smile.gif
Cheers guys
Tim
