hey guys, this might sound stupid but i just dont know it.
These antifoulers used for the test pipe.. where do you get 'm? is is a standard hardware supply item that every store has? or was it hard getting 'm? what about the size? thanks

I got mine from shucks auto supply, just about any auto parts store should have them. As far as size, they are 18mm spark plug anti-foulers. The only pain was drilling the first non-fouler, because it is stainless steel, so have to drill numerous times before getting to the right size (19/32"). Other than that, the install is pretty straight forward. Here is a link for the install, scroll down towards the bottom for the info relating to the non-foulers:

I just posted something a few weeks ago about an alternative to the anti-foulers - using a diode. It should be relatively easy to find if you search for anti-fouler diode CEL etc.

It is an electronic solution to the physical installation of the anti-foulers that has worked for me for several thousand miles with no CEL.

AF's can be gotten at most auto parts stores it seems.

I've also done the diode mod. Took like 15 mins. No CEL for me for over 500 miles now.

I didn't see that you had a 2000 A4, the anti-fouler mod doesn't work all that well on your engines, usually a CEL will appear after some time, I would take the diode route.
