So I started to take out my air filter box today and in the process I discovered the small pre filter (looks like a lint screen for a dryer)in the intake tube. It was a mess with all sorts of dust and leaves. After a through clean the car ran much faster. I could not believe it!

Has anyone else found this to help with performance.

It also seemed to run cooler.

old news for S4 B6 guys. It gets full of twigs and leaves.

some people remove it, and Audi recommends cleaning every 10k, IIRC.

when i removed mine to clean, it dumped some debris into the main airbox. had to clean that out of there. this was w/o filter change, but just cleaning the snow screen.

Accessed by dismantling the intake manifold.

Definitely worth cleaning out every now &amp; then (every oil change, for example).
