I have a T04 turbo, no intake or MAF, just a filter on the turbo, need a new one, wanted to know what the best one is, and the cheapest.

I'm using a K&N. Phinsup sells them here, here is a link...

K&N FPIK 57-5005

I'm running a NAPA Gold, High performance stock filter element https://www.nopistons.com/forums/pub...DIR#>/wink.png. With N/A though, I noticed no difference between cone and stock air box, so I went with the stock since I had a crappy ebay cone and I was worried about it falling apart.



I hear apexi is very good and about as expensive as K&N.

go with the autozone spectra for $20. they even come in 4 colors: red, yellow, blue, and crome.

Whats that little box behind the cone? is that atatched to it? and is that factory? and just outa curiousity uh... what was i gonna ask.. ooo and does keeping that center air intake thingy help a little bit too?

That middle thing is the MAF sensor. It calculates how much air is coming in, so adapt the fueling. That style is only on the s4 cars. s5 is different.

the center air intake thigny is the radiator shroud.

the center thing i just left over from the stock air box. i figured it might get a little more air in there.
