Hi, I've just bought a 1.8T (163) Silver A4 Cab on an 03 plate. I'm currently loving the Audi experience but was after some general advice. 1. Ive looked into obtaining a K&N induction kit, but having probs obtaining the part no, the K&N site says its 57-0593 but looked on others and it says this part only covers upto 2002 plates, also has anyone got one fitted on this engine, if so whats it like. 2. Has anybody done any mods to a cab around the same age, if so could you post some pics, I'm a bit scarred to change the appearance at the minute!!
