Thanks guys.. really I wanted to get a better sound to the car more than anything else I am going to get a milltek exhaust aswell but heard that there are a few issues with some of the Inductions so your input would be extremly valuable.. thanks again...
You really don't need a £1k+ exhaust system on this engine....you won't get much in the way of bhp gains,as NHn has already explained on your other thread,and it WILL cost an arm and a leg,assuming either Milltek or Blueflame will build/sell you one for a non-turbo A3...which they do not currently list.
Oiled induction filters are generally accepted to be a bad idea as some of that can coat your MAF sensor and lead to errors,and others based on new piping and cone filters will both cost a lot,and offer you little in return.
Simple panel filters such as the Pipercross will do the job,and may give you a few extra horses,but all of those gains,including the 10-12bhp from a remap will only come at the top of the rev range,and you'll have to work it pretty hard to notice anything much.
You may be better advised to spend a bit on aftermarket springs and roll bars if you really want to spend,as this may enable you to use the current power more effectively......even that isn't cheap.
Just step back a bit and think carefully about the costs and gains.
