Right my s3 is coming up to 80k so time for a service.my last service was at 71k. i changed spark plugs,engine oil,engine oil filter,fuel filter and cleaned my air filter.

Im planning to change the following:
Engine oil im currently using mobil 1 0w40
Oil filter
Air filter i have a pipercross panel filter,poss due a new one
Fuel filter
Haldex oil and filter
Brake fluid.

So basically what oil do people recommend as i said im using mobil1 0w40.
What air filter im thinking maybe a green cotton or k&n panel filter.
should i change my sparks again and if so what do people recommend.

Im also running standard brake setup which is pretty poor dont wanna spend a bomb but maybe mintex or green stuff pads.

all ideas welcome cheers dan
