Audi B6 S4 Replacement Air Filters

[Pault5678]

Hi,

I have a B6 S4 and am debating weather to buy a replacement air filter panel for it. I have read a couple of stories on the net which suggest that straying from OEM might be a bad idea.

Does anyone have advice?

Cheers.

I am new to these cars (had my B7 S4 for 6 weeks or so) and have been considering getting an aftermarket panel filter (ITG perhaps) as I have read on forums here in the states that it can make a bit of difference (but as usual, mostly with chip and full aftermarket exhaust, still the gains are very small). I haven't delved into the engine bay that much but I also read that there is a pre-filter in the air intake and removing this frees up some flow and does no harm - but then also that the airbox has a tendency to collect masses of debris. If the pre-filter is the limiting factor on intake, then changing the panel will surely do nothing? Removing the pre-filter and changing the panel is the only way - and I can't see that a decent aftermarket filter will be a bad thing and will stop just as much crud as the OEM one... hmm...the jury is still out for me.
