If you're sticking with the paper filter or even switching to a higher performance filter, be sure to replace it or give it a shake out fairly regularly, you'd be amazed at how much crap these things pick up.
I had this myself, didn't. Fit them properly and they shattered when I tried to take out. Spent many hours with the lighting unit out with a hoover and an old coat hanger with some double sided tape trying to get all the remnants out. Take your time and you should be able to get it all out.
Haven't used them before but heard good things about them on other VAG forums. Only problem is that they are based in Croydon......................
There are numerous different mapping companies outhere if you want to consider an alternative to APR.
PS I have Bluefin and am happy with it...
I installed a set of Eibach pro springs to my 2.0T quattro s-line, it actually improved the quality of the ride without a noticeable drop in ride height
It hasn't, however, transfored the car's handling into that of a go-cart but I would say its an improvement!
I put Vredestein Ultrac Sessantas on my 18s when I couldn't find any F1s. A bit cheaper and just as grippy. Will have to see how the wear goes as only done a couplke of 1000 miles on them. Not too noisy either
Pretty sure the standard offset for the A3 is ET 54.
The A4 wheels are 18x8 whereas the A3 wheels are 18x7.5.
There are a couple of A3 sets on ebay at the moment:
