Yes it is an AGG
The main thing i noticed from the airbox & airflow meter woz the noise obviously
seems a bit more willing at top end now altho i have been raggin it about a bit more since i did those cos its more fun now its noisey! Definately noticed a difference with cat pipe & doin the airbox.
i did the cat pipe the day b4 the airbox so its difficult to tell how much difference the airbox made not being used 2 it with no cat yet.
Other engine mods im thinking of are exhaust system (dont want anything loud tho so i dont know wot 2 go for), cam, chip, manifold work and if i can manage to save a bit of money up then may eventually get onto some head work.
Do most the work maself cos i work at listers vw so that helps the cost a bit heh.
Feel free to give me any suggestions u may have as to mods i can do cos im short of ideas. Not sure wot i can do without messing up emissions to get it through an MOT.
